What can we do to catch this Green Bond Issue ?
Now is a good opportunity to invest solar power system in Australia, cost dropped and issue comes . Call us for total solution of On-Grid solar power system / Off-Grid solar power system and door to door services to Australia on our website.Clean Energy Finance Corporation invests $10 million in green bond issue
An Australia-first climate bond is set to boost investment in the nation’s rapidly growing solar energy market.The Clean Energy Finance Corporation (CEFC) has invested $10 million in a $90.9 million green bond issue by FlexiGroup Ltd. Rooftop solar makes up a large proportion of the investment, with a smaller allocation for small-scale energy storage.Green or climate bonds finance a range of renewable energy projects. This is the first time small-scale batteries are included in the Australian green bond market.
Fast-growing solar storage market perfect for green bonds
Australia’s home solar battery market has lagged behind the growth of solar panels. Yet battery prices are rapidly falling.Data from Bloomberg New Energy Finance (BNEF) shows nearly three-quarters of Australia’s rooftop solar capacity will include battery storage by mid-century.By 2050 Australia will have more than 6 million rooftop solar power systems installed. Close to 4.5 million of these will also feature small-scale solar batteries.BNEF says battery prices will also fall by more than 50 per cent through to 2030. Australia’s solar storage market could then become a $1.7 trillion industry.
How green bonds work
According to Gilbert & Tobin, green bonds create a large pool of capital to fund environmentally responsible projects.They operate like traditional bonds, but with a focus on eco-friendly outcomes.The CEFC notes that institutional investors in Australia increasingly want to fund carbon reduction assets like solar farms. The new climate bond will help them develop ‘green’ portfolios to reduce Australia’s carbon footprint.
This is therefore critically important. The Climate Council’s ‘expert statement’ backed by 28 climate and energy experts states Australia’s greenhouse gas emissions are rising.
The emergence of green bonds around the world
Data reported by Gilbert & Tobin shows huge growth in the global green bond market.It has grown from less than $5 billion in 2010 to more than $150 billion in 2017 and 2018. Climate Bonds Initiatives (CBI) data predicts it will reach $351 billion this year.National Australia Bank was the first Australian bank to launch both an offshore green bond in March 2017 and a climate bond in 2014.FlexiGroup Ltd issued Australia’s first asset-backed green bond in 2016.The Australian Government owns the CEFC, which mobilises capital investment in renewable energy. The CEFC has committed $489 million to 11 bond issuances since it began in 2013.From: energymatters.com.au
Bill Gates: Solar is not the energy solution Africa needs -- BUT HOW WE GO ?
Bill Gates once again shunned solar power from his vision for energy access in Africa in his talk at the University of
Pretoria in South Africa on Sunday, where he argued that whilst “cheap, clean
energy” is what Africa needs, solar does not fit the bill.
During the delivery of his Nelson Mandela
Annual Lecture, the Microsoft founder and philanthropist identified that
Africa, like the rest of the world, is in need of a “breakthrough energy
miracle that provides cheap, clean energy for everyone.”
Africa is more dependent on such a
phenomenon than other continents, because seven in ten Africans still lack
power at present, while more than 500 million Africans still will not have
electricity by 2040.
This is not the first time Gates has taken
a less than welcoming stance to solar power. In February, during an interview
with a news outlet, he echoed a similar thought. "When I say 'an energy
miracle'," he said, "I mean that there will be some form of energy
whose 24-hour cost really is competitive with hydrocarbons given, say, 20 years
of learning curve.
"You invent it, then you look at how
much its costs go down over the next 20 years, that it really beats
hydrocarbons.
"You might say, well, aren’t people
saying that about wind and solar today? Not really. Only in the super-narrow
sense that the capital costs per output, when the wind is blowing, is slightly
lower."
In fact, Gates has been advocating
anti-solar sentiment for a while. In 2014, he blogged about energy poverty,
arguing for outdated fossil fuel solutions to tackle the electricity deficit in
underdeveloped economies, characterising energy poverty as a climate issue.
Solar is ‘not enough’
In the speech on Sunday, the software
entrepreneur recommended increased investment in renewables, namely hydropower
and geothermal. He went on to argue that recently launched solar power
initiatives have not been enough:
“There has been a lot of experimentation with small-scale renewable
energy, including micro solar,” he said. “This approach can provide individuals
with some electricity for basic purposes, but it’s not going to be the solution
for the continent as a whole.”
PV Tech contacted the South African
Photovoltaic Industry Association (SAPVIA), who vehemently disagreed with
Gates’ sentiments.
“To downplay the role that solar photovoltaics (PV) can play as part
of a unique African energy mix in the strive to alleviate Africa’s energy
constraints would be irresponsible,” a spokesperson said, whilst citing data
that should deem solar a ‘no brainer’ solution for
Africa: “Africa has 7 of the 10 sunniest countries on earth and, according to
IHS Technology, a US-based economic and energy market research company,
Africa’s total solar power–generating capacity is projected to reach 3,380MW by
2017.”
Solar deployment in Africa
In fact, solar power is undergoing rapid
deployment and implementation as many countries across the continent are
battling energy crises and look to alternatives to expensive fossil fuels such
as diesel and coal. A series of feed-in tariffs and solar tenders have offered
a foray into a solution that not only is clean and inexpensive, but is easily
accessible.
In South Africa in particular, the
Renewable Energy Independent Power Producer Procurement Programme (REIPPPP) has
successfully awarded 965MW of new solar capacity, which SAPVIA points out “is
being delivered on time and on budget”.
“The rapidly escalating uptake of the technology in the rest of
Africa can be clearly seen,” argued SAPVIA. “Expedited solar PV roll-out is
being seen as supportive policies and regulations, such as the Get FIT
Programme are developed and implemented. These policies and programmes,
combined with the drop in the cost of PV technology (currently fully off-grid
solar-PV technologies deployed at site can be deployed for as little as US$
0.15/kWh and they do not require additional expensive transmission networks to
move the electricity around), we see solar PV will make a significant impact
on Africa and its energy challenges.
“One can expect – as has happened in South Africa – as the necessary
supportive policies and regulations are scaled up, the rest of Africa will
experience an increased uptake of solar PV technology. New renewable energy
markets in Africa are already showing greater appeal to international and local
investors – further spurring the uptake of solar PV in African markets.”

With recent reports estimating that six hundred million people are without access to electricity in sub-Saharan Africa, significant and sustained investment is required across Africa’s entire energy generation and supply value chain.The trend is clear.As the size and number of large government-funded and implemented non-renewable power projects in Africa has decreased there has been an uptick in smaller mixed public-private (or entirely private) off-grid power projects with rational, local end-user funding.While large utility-owned non-renewable projects will remain an important part of the energy value chain, off-grid offers a faster way to close Africa’s power gap.Renewables – especially privately or partially privately-funded new off-grid and captive power solutions - are set to sustain and expand investment while increasing affordability and access to electricity in Africa’s rapidly evolving energy landscape.“As such, looking ahead, most of the growth in terms of households covered by off-grid power solutions could come from service-platform developers able to leverage strong distribution platforms,” says van Tonder.Off-grid strategyDeveloping this diverse energy supply and generation mix will require an equally diverse funding mix if it is to be sustainable.The global trend towards public private partnerships (PPPs) is currently playing out across the African continent. While non-cost reflective tariffs in some countries make PPP financing solutions more challenging, recent moves towards cost-reflective tariffs in Mozambique, Ghana and Zambia facilitate the relevance of PPPs as a viable funding model – providing the potential to further improve the electrification rates across Africa.Adding localised privately funded and user-pay solutions to the national grid or allowing entirely independent off-grid solutions to take pressure off the grid, “provides debt-stressed African sovereigns with a way of funding the development of power projects - by moving substantial investment off government balance sheets,” explains van Tonder.Future Green Technology Co., Ltd., whose establisher worked long in Africa, commit to provide basic power supply to where it needed.

Maintenance-free
lead-acid battery
The
correct use and maintenance of the battery mainly have the following 9 points:
1.
Check if the fixing bolt of the battery on the bracket is tight. If the
installation is not secure, the housing will be damaged due to the running
vibration. Also, do not place metal objects on the battery to prevent short
circuits.
2.
Always check if the pole and terminal are connected reliably. To prevent
oxidation of the terminal, a protective agent such as petroleum jelly can be
applied.
3.
It is not possible to check the battery's power by direct ignition
(short-circuit test), which may cause damage to the battery.
4.
Ordinary lead-acid batteries should pay attention to the regular addition of
distilled water. The dry charge battery should be properly charged before use.
As for the maintenance-free battery that can be added with water, it is not
impossible to maintain proper inspection. If necessary, supplement the
distilled water to help extend the service life.
5.
The air holes on the battery cover should be unobstructed. When the battery is
charged, a large amount of air bubbles will be generated. If the vent hole is
blocked, the gas cannot escape. When the pressure is increased to a certain
extent, the battery case will burst.
6.
There is often a yellow-white paste around the battery pole and cover. This is
because sulfuric acid corrodes the root column, line card, fixing frame, etc.
The resistance of these substances is very large and should be removed in time.
7.
When the two or more batteries need to be used in series, the capacity of the
batteries is preferably equal. Otherwise it will affect the battery life.
Generally,
such maintenance-free batteries can be stored for 10 months from the factory to
the use, and the voltage and capacitance remain unchanged. The voltage and
capacitance of the poor quality will decrease after about 3 months from the
factory. If you choose to leave the production date for 3 months at the time of
purchase, you can check whether the voltage and capacitance of the battery meet
the requirements on the manual. If the voltage and capacitance are reduced, the
material inside is not good, then the quality is definitely not good. It may be
that the water battery is disguised after being charged by the dealer.
8.
Maintenance of maintenance-free lead-acid battery electrolyte
Check
the residual acid in the acid pool. If it is less than 1/4 of the acid pool,
the pure water that meets the technical requirements should be injected into
the acid-containing tank to make it reach 2/3 of the liquid level. The amount
of concentrated sulfuric acid in accordance with the technical requirements is
added in a ratio of about 4:1. When adding concentrated sulfuric acid, first
put the plastic stirrer into the acid pool for stirring, then slowly pour the
concentrated sulfuric acid into the acid pool to prevent the sulfuric acid from
splashing; when the acid is mixed, pay attention to the temperature of the acid
pool. When the temperature in the acid pool is greater than 60 °C, immediately
stop adding sulfuric acid, add pure water or stir to cool, when the temperature
of the acid liquid drops below 45 °C, then re-adjust according to the required
acid specific gravity by adding pure water or sulfuric acid; 5.2.3 Preparation
of electrolyte for battery: When the temperature of the electrolyte in the acid
pool is lowered to room temperature, the actual value is measured by a
hydrometer and a thermometer. When the actual temperature and the specific
gravity of the electrolyte meet the requirements, the weight of the dilute
sulfuric acid is taken. .4 If the preparation of the electrolyte is not at room
temperature, it can be corrected according to the following formula: d25 = dt +
0.00075 × (t-25) (g / cm3): where d25 represents the density converted to the
standard temperature (25 ° C); Dt is the measured density; t is the temperature
of the electrolyte when the specific gravity is measured.
9.
The battery should not be placed for a long time, and the battery that has been
deactivated for a long time should be charged and maintained regularly.
There
is an internal self-discharge problem in the battery. The self-discharge amount
is about 2% per day. That is to say, a fully charged battery, even if it is not
used at a time, will be discharged by internal self-discharge after a long
time. In the case of a battery that is depleted, the plates are quickly
sulfated, which greatly impairs the storage capacity. Therefore, the battery
that has been deactivated for a long time should be recharged once a month for
the battery, about 10 hours each time.
If
the battery has been left for a long time, the battery vulcanization phenomenon
occurs. After the battery is fully charged, it can be repaired by using the
battery online maintenance instrument for about 20 days, and the capacity can
be restored.

In
recent years, as the world importance for
the photovoltaic industry, solar power systems have been widely
utilized in the life. But what should happen to such a
high-tech thing? The following Future Green Technology Co., Ltd.
summarized the common faults and solutions for photovoltaic
power generation systems for everyone, and hopes to help everyone.
Frequently asked questions when debugging off-grid
systems:
First, the inverter LCD
is not displayed
Reason analysis:
(1)
The battery voltage is not enough. When the battery is just shipped from
the factory, it is usually fully charged, but if the battery is not used for a
long time, it will be slowly discharged (self-discharge). Off-grid system voltages
are 12V, 24V, 48V, 96V, etc. Some applications require
multiple batteries in series to meet the system voltage. If the connection
cable is not done well, the battery voltage will be insufficient.
(2)
The battery terminals are reversed. The battery terminals have positive
and negative poles, generally red for the positive pole and black for the
negative pole.
(3)
The DC switch is not closed or the switch is faulty.
Solution:
(1)
If the battery voltage is not enough, the system can't work, the solar energy
can't charge the battery, go to another place to charge the battery to more
than 30%.
(2) If
the problem is the line pressure profile measurements of various electrical battery
voltage with a multi-meter. When the voltage is normal, the
total voltage is the sum of the voltages of each battery. If
there is no voltage, check whether the DC switch, terminal block, cable
connector, etc. are normal.
(3)
If the battery voltage is normal, the wiring is normal, the switch is also
turned on, and the inverter is still not displayed, it may be that the inverter
has failed, and the manufacturer should be notified for maintenance.
Second, the battery cannot be charged
Possible reasons:
( 1 )
Component reasons: The component voltage is not enough, the sunlight is low,
and the components and DC cable are not well wired.
( 2 )
The battery circuit wiring is not good.
( 3 )
The battery is fully charged and reaches the highest voltage.
Solution:
( 1 )
Check whether the DC switch, terminal block, cable connector, component,
battery, etc. are normal. If there are multiple components, separate the
tests separately.
( 2 )
When the battery reaches full charge , it can't be recharged, but the
voltage is different when different batteries are fully charged. For example,
the battery with rated voltage is 12V. When the battery is fully charged,
the voltage is between 12.8~13.5V. The specific gravity of the
electrolyte when the battery is fully charged. The maximum pressure
limit should be adjusted according to the model of the battery.
(3) Input
Overcurrent: battery charging current is generally 0.1C-0.2C, the
maximum does not exceed 0.3C, and for example, a lead-acid
battery section 12V200AH, the charging current is
generally between 20A to 40A, the maximum should not
exceed 60A. Assembly to the power controller and the power mate.
( 4 )
Input overvoltage: The input voltage of the component is too high, check the
voltage of the panel. If it is high, the possible reason is that the number of
strings in the panel is too large, and the number of strings in the panel
is reduced.
Third, the inverter shows overload or cannot start
Possible reason:
( 1 )
Inverter overload: The inverter overload exceeds the time range, the load power
exceeds the maximum value, and the load is adjusted.
( 2 )
Battery overload: The discharge current is generally 0.2C-0.3C , the
maximum does not exceed 0.5C , 1 section 12V200AH lead-acid
battery, the maximum output power does not exceed 2400W , different
manufacturers, different models, the specific values are different .
(3) The
load is a load elevator or the like can not be directly connected to the output
of the inverter, because the elevator during lowering, reverse the motor
will produce a counter electromotive force when entering the
inverter, the inverter is damaged. If an off-grid system is necessary,
it is recommended to add a frequency converter between the inverter and the
elevator motor.
( 4 )
Inductive load starting power is too large.
Solution:
The
rated power of the load is lower than the inverter power, and the peak power of
the load cannot be greater than 1.5 times the rated power of the
inverter.
Battery common problems:
Short circuit phenomenon and cause:
The
short circuit of the lead-acid battery refers to the connection of the positive
and negative electrodes inside the lead-acid battery. The short circuit
phenomenon of lead-acid batteries is mainly manifested in the following
aspects:
The
open circuit voltage is low and the closed circuit voltage (discharge) quickly
reaches the termination voltage. When a large current is discharged, the
terminal voltage drops rapidly to zero. When the circuit is open, the
electrolyte density is very low, and the electrolyte may freeze in a low
temperature environment. When charging, the voltage rises very slowly and
remains low (sometimes reduced to zero). When charging, the
temperature of the electrolyte rises very quickly. When charging, the
electrolyte density rises slowly or almost unchanged. Do not take
bubbles or gas when charging.

In recent years, Disney has continued to
expand its renewable energy deployment and is committed to the next
environmental management milestone, hoping to significantly reduce carbon emissions
by 2020, reducing global greenhouse gas emissions by 50% compared to 2012. In
order to achieve the 2020 carbon reduction target, Disneyland in various
countries is also in full swing to build renewable energy facilities.
Hong Kong Disneyland
Hong Kong Disneyland said it has begun to
build the largest photovoltaic power generation system in Hong Kong. The park
will install more than 4,500 solar panels on the roof of 14 buildings in the
resort, while the total area equal to a standard football field. The total
power generation will be expected to be as high as 1.86 million kWh, equivalent
to one year's electricity consumption of 564 three-person households.
The project has two periods and will be
completed by the end of December 2019. Among the eight buildings in the first
phase, the buildings with the largest number of solar panels installed in a
single location are the rooftops of the “small world” of amusement facilities,
with more than 1,190 solar panels. The second phase of the plan (September to
December) will be installed on the roof of six buildings in the resort,
including the construction of amusement facilities, with an additional
installation of more than 1,000 solar panels. It is expected that after the
completion of the project, one third of the electrical energy will be provided.
.
Through this project, the generated
electricity will be directly transferred to the public power grid. It is
expected that Hong Kong Disneyland and solar panel supplier can share an
additional income of approximately HK$5 million per year. Hong Kong Disneyland
will use the funds to pay for project development costs, system maintenance and
other environmental projects.
The head of the Hong Kong Disneyland said
that the project uses a new wireless real-time monitoring system, through the
mobile phone program, each online solar panel can be independently monitored
on-line for maximum performance.
Shanghai Disney: Recycling waste heat for
heating and cooling
Shanghai Disneyland opened in 2015. The
park introduced distributed energy technology, turning waste heat into the
power and providing to fairy tale scenes and rides.
Providing energy for Shanghai Disneyland is
a natural gas “triple supply” energy station that is separated from the park by
a road. This 20,000 square meter building is a “comprehensive processing plant”
that uses pipe network systems and cables to provide electricity, steam and air
conditioning for use in the covered area.
Disney has four pipes of steam, cold air,
hot water and electricity from the energy station across the road. It uses part
of the waste heat from the power station to make steam for use in some electric
games that require compressed air. Another part of waste heat is used to heating
water, transport to the kitchen, hotel; and waste heat was used by the central
air conditioning using bromide technology to chemical reaction for cooling.
It is known that after the introduction of
distributed energy technology in Shanghai Disneyland, the energy utilization
rate will reach 80% or more, which is about 1 times higher than the traditional
model. At the same time, the “triple supply” energy station can save 20,000
tons of standard coal and reduce carbon dioxide emissions by about 75,000 tons
per year.
Disneyland Paris: First wastewater
treatment and recycling system
With the idea of “renovating the water
equipment of the park directly with its smaller rainwater recycling system”,
Disneyland built a wastewater treatment and recycling system in the park in
2013, becoming the first installation park in Europe. The system produces 1,389
tons of reclaimed water per minute. Water will be used to clean streets,
waterways for recreational facilities, roadside plant irrigation and cooling
pools for power plants. The wastewater treatment plant has saved 1.1 million
cubic meters of water, equivalent to the annual water consumption of 7,384
households in France.
In 2017, Disneyland Paris used 2,000 meters
of underground geothermal energy to successfully provide energy for two theme
parks and restaurants, allowing the water temperature of lagoon up to 85 ° C.
It can produce 20GWh of energy per year with zero carbon, reducing the carbon
footprint of Paris Paradise.
In 2019, Disneyland Paris announced a
series of environmental protection initiatives that will replace plastic straws
with fully biodegradable paper straws, which are only available upon request by
customers. The store will stop offering free plastic bags and the main raw
material for sale will be recycled plastics Bags; many hotels in the park stop
providing small bottles of shower gel and shampoo in the bathroom of the room,
and use large bottles that can be filled multiple times.
Disneyland Paris also attaches great
importance to the development of solar projects. At present, it has proposed
plans to install solar panels in a park covering an area of about 22 square
kilometers. If the solar projects are completed on schedule, solar power can
also meet the increasing demand for electricity in Paris. After the expansion
of the park in 2002, the demand for electricity and natural gas increased by
16.7% and 28.1% respectively compared with 2001. With the arrival of the new
park in 2025, more power sources will be needed afterwards. The higher efficiency
of solar photovoltaic, the better the paradise will be.
Orlando Disney: Developing large-scale
solar installations
Opened in Florida in 1971, the Orlando
Disney Resort is the world's largest Disney resort and currently has four theme
parks – the Future World, the Animal Kingdom, the Hollywood Studios, and the
Magic Kingdom. The Walt Disney Company has reached an agreement with solar
energy company, Origis Energy USA, to build 50MW solar equipment at the Orlando
Disney Resort, which is expected to power two theme parks.
The solar facility will be built around the
animal kingdom, covering 270 acres and installing 518,000 pcs of solar panels.
It is expected to reduce emissions of 57,000 tons of greenhouse gases,
equivalent to 9,300 vehicles. The new solar power plant is also in line with
the construction of the Disney Animal Kingdom, the first park to protect
animals and protect the planet.
This equipment is not the first solar
photovoltaic facility in Disneyland, Florida. As early as April 2016, it had
built 5MW and about 48,000 solar panels in the future world theme park, which
is the largest Mickey pattern in earth surface. The development and
construction of this 50MW solar power station will further provide clean energy
for the Orlando Disneyland.
Tokyo Disney: Powered by roof solar panels
in the park
Tokyo Disneyland has seven themed areas
with 35 wonderful performances. The common feature is that “everything is
active and there is a lot of sound”. What makes it possible is the "electronic
sound action device" developed by Japan itself. Driven by such a device,
the total number of 2,000 or more puppets and animals in the park is enough to
achieve a real degree of sham.
The power of these electronic sound action
devices comes from the solar panels on the roof of the park. These devices also
supply power for the night light parade. Tokyo Disneyland has installed a total
of 600KW solar energy on the roof of 8 buildings.
It is worth mentioning that at the
beginning of the construction, Tokyo Disneyland has arranged more than 300,000
trees in the park. 24% (200,000 square meters) of the park is a tree planting
green.
Disneyland, California: laying more than
1,400 solar panels
In 2016, Disneyland, Calif., said it plans
to install solar panels on the roof of the campus buildings. Currently, the
park has used solar energy to supply electricity.
A total of more than 1,400 solar panels
have been installed at the Disneyland Park in California. The solar array
covers a total of 40,000 square feet and generates enough electricity to power
100 homes in the Anaheim area.

Is solar power supply in China's cities cheaper than grid power?
Recent studies have shown that distributed solar energy can provide lower
electricity prices than fossil energy generation in many cities in China.
Although solar energy is more low-carbon, it is often considered more
expensive than fossil energy. However, according to a recently published study,
in many cities in China, solar energy can provide lower electricity prices than
fossil fuels without subsidies. The research team believes that with the rapid
growth of China's electricity demand and the advancement of clean energy
technologies, renewable energy investment will become more attractive. However,
some experts and enterprise power users believe that the practical obstacles
facing solar power still need to be solved.
Cheaper solar energy
Grid parity – the unsubsidized total cost of renewable energy is equal to
the cost of fossil fuels, even lower than the cost of fossil fuels – is
considered a key turning point in renewable energy expansion, marking a
theoretically more investment flow to clean energy and technology.
According to the latest research published in the journal Nature and
Energy, the research team of the Royal Institute of Technology in Sweden calculated
the power generation price of megawatt-scale distributed photovoltaic power
generation projects in 344 cities in China from the user side and the power
generation side, respectively. The electricity price of the urban grid is
compared with the local desulfurized coal price (that is, the electricity price
sold by the coal-fired power company to the grid company). Among them, the
urban grid electricity price is the user side electricity price, including
power generation cost, transmission and distribution cost, enterprise profit,
government funds, and surcharges; the power generation side electricity price
includes power generation cost and power plant profit rate.
The study found that even in the absence of state subsidies (and their
expected distortions), on the user side, the total solar cost of all 344
research cities is lower than the city's electricity price; In 76 cities (22%),
solar power generation prices are flat or lower than coal-fired power plants.
Studies have shown that investments in renewable energy will not only be
“moral choices” for climate and environmental concerns, but also for legitimate
considerations of economic interest.
The study also pointed out that there are differences in price
competitiveness between different cities, mainly due to the solar radiation
level of each city, the on-grid price of desulfurization coal-fired coal, the
price of the electricity market and the investment cost of photovoltaic system.
However, in addition to technical factors, there are still many objective
conditions that restrict the competitiveness of solar power generation in the
electricity market. Tao Ye, deputy director of the Renewable Energy Development
Center of the Energy Research Institute of the National Development and Reform
Commission, believes that some of the conditions in the theoretical economic
measurement are uncertain. Under the current power market environment,
coal-fired power and renewable energy have competition in the acquisition of
market space, and coal-fired power has the ability to further reduce the price
of online. In addition, non-technical costs such as land and roof acquisition
may also increase photovoltaic power generation costs.
Support policies to promote photovoltaic development
The initial goal of China's solar energy industry development is mainly
to face the rural areas and popularize power supply and poverty alleviation in
remote areas. After 30 years of development, today's solar energy industry in
China has grown to more than double the photovoltaic panels of any other
country. The rapid decline in marginal cost is largely due to government
support policies for the photovoltaic industry. According to statistics, since
2000, the Chinese government has introduced more than 100 policies to support
the photovoltaic industry.
For example, in 2013 and 2014, the State Grid and the National Energy
Administration introduced support policies for distributed solar energy, which
cleared some of the institutional barriers for the generation and development
of small-scale solar power generators. At the same time, the subsidy policy for
photovoltaic power generation is also very powerful: for centralized
photovoltaic power plants, the part of the on-grid electricity price higher
than the coal-fired electricity price is subsidized by the national renewable
energy development fund, and the distributed electricity is fully charged.
subsidy. With the support of substantial financial subsidies, photovoltaic
power generation has achieved a surge in installed capacity in a shorter period
of time. In 2011, China's cumulative PV installed capacity was 6.02GW, and the
cumulative installed capacity in 2014 was 26.52GW. By the end of 2018, the
cumulative installed capacity has exceeded 170GW, of which distributed PV
installed accounts for about 29%.
However, continuous government subsidies have also created a market of
“excessive prosperity”, and speculators who have spawned “fraud subsidies” in
the early days have entered the photovoltaic industry.
In 2018, under the background of the central renewable energy power
generation subsidy exceeding 100 billion yuan, the Chinese government has
greatly reduced the subsidies to the solar industry, which has brought a great
shock to the industry, but this shock has also promoted the independence of the
industry. growing up. Tao Ye said, “20% of the new PV projects in 2019 achieved
parity or low prices, and this target is expected to exceed 35% in 2020”. With
the large-scale centralized solar power project in the western region facing a
difficult situation, the construction of distributed photovoltaic projects
closer to the power consumption center in the developed eastern region has
become a new trend. In 2017 alone, China's new distributed PV installations
reached 19.44GW, the sum of the previous three years.
Realistic bottleneck
The volatility and instability of renewable energy generation is
considered to be one of the bottlenecks that have long plagued the industry.
However, Zhang Shuwei, director of the Zall's Environment (Beijing) Research
Center and chief energy economist, believes that this is not the reason why the
grid refuses to consume renewable energy, because the development of renewable
energy has never been for system balance purposes, but to reduce emissions; In
addition, the role of the grid is to deal with various fluctuations and
uncertainties. The key to the problem is whether the solution is more
cost-effective and whether it is the lowest cost option.
Land resources are another bottleneck limiting the expansion of the solar
industry. Therefore, distributed photovoltaic projects using rooftop resources
are considered to have great potential and can save a lot of cost for
enterprises, especially for power-hungry technology parks, industrial
enterprises, and data centers with high power consumption in recent years.
Wait. However, in reality, it is not smooth to promote rooftop photovoltaic
power generation due to policy influence. For example, the property rights of
Chinese urban roofs are often unclear, and enterprises have difficulty in
obtaining roof resources.
Another obstacle to limiting the development of renewable energy
generation is the lack of voice for business users. Traditionally, companies
using electricity that is uniformly delivered by grid companies cannot
determine the source of electricity themselves.
WHAT THE FUTURE
OF GREEN TECHNOLOGY LIKES
In recent years, global investments in green
technology have increased by almost 20% in various sectors such as energy,
innovation, and production. With more pressing environmental problems around
the world such as energy shortages, global warming, pollution, urban population
growth, and others, individuals, small and large companies and countries are
looking to the future to see how adapting to greener technologies can help to
change the world.
Finding a way to curb our huge dependence on
fossil fuels and reduce pollution depends on how we develop new green
technology and greener solutions. We need alternative and more efficient
solutions to shape the future. Below, we look at what the future of green
technology will look like.
THE MAIN FOCUS ON THE FUTURE OF GREEN
TECHNOLOGY
From small businesses, innovators, equipment
manufacturers and service providers to global manufacturing giants, investments
in green technology are considered both small and large scale. To understand
what serves as the basis for this rapid growth, it is necessary to examine the
key areas of interest.
Power
Energy is considered to be the most pressing
green technology issue. There is no doubt that the world today is heading into
the unknown if we continue to rely on fossil fuels. Fortunately, the energy
sector worldwide is focusing more on the development of alternative fuels and
energy sources.
The manufacturing sector will also play a
significant role in the production of more energy-efficient products which
contribute significantly to adopting the green way of life to the future.
Sustainability
Companies and service providers are taking the
necessary measures and are making great efforts to meet social needs with
sustainable solutions that will be used now and in the future without damaging
or depleting natural resources.
For example, car wash companies are opting for
more efficient washing systems that help them recycle the water used to reduce
waste. If you have a transit washing system, you would see how these solutions
can help you save on water bills while offering a sustainable solution to
reduce water waste.
Source reduction
Companies in all manufacturing and industrial
sectors are also creating solutions geared towards reducing waste and pollution
by changing the way products are manufactured and consumed by end-users and
consumers on the market. To this end, various steps have been taken:
- Establish waste-reducing practices.
- Recycling of waste.
- Purchase of remanufactured products such as
equipment and parts.
- Opting for alternatives of ecological
products.
- Adoption of ecological policies in the
sectors of products and services.
Innovation
Innovation is the engine of future ecological
technologies and solutions. More attention is now being paid to developing
better alternatives to the types of technologies that have been shown to pose a
danger to our environment and our health.
Innovation will play a huge role in changing
trends in the use of fossil fuels, creating solutions for urban industrial
pollution and developing alternatives for chemical-intensive agriculture.
Green chemistry and nanotechnology
The future of green technology will largely
depend on how companies and organizations learn to invent, develop, manipulate
and apply different processes to products and materials at different levels.
Whether its chemical processes or
nanotechnologies, this will play a huge role in helping us transform the
production of chemical products and processes to reduce and eliminate the use
and generation of hazardous materials and substances.
Regenerative design
A large percentage of waste in the world is
caused by the use of products such as plastic that are not recyclable or
non-degradable. The end of the cycle of use of products that do not respect the
environment is now at the heart of green technology. Manufacturers are now
creating products that can be completely reused, recycled or regenerated.
Vitality
In a world where the implementation of green
policies is still slow, especially in developing countries, the viability of
green technology in the future is very important. Develop economic activity
centers or ecological centers that focus on creating innovative products and
technologies that truly benefit the environment and ensure that health safety
is fundamental.
Projects, organizations, and centers inspired
by green technology - financed by the government or private - play a huge role
in accelerating the implementation of ecological solutions and in creating
awareness and careers that focus on making the planet a safer and better place.
NEW EXCITING TECHNOLOGIES FOR A GREEN FUTURE
Solar power
The solar energy industry is growing rapidly
and is aiming to achieve sufficient solar capacity in the future. Being one of
the main ecological technologies with implementation all over the world, many
innovations arrive every day.
From shingles and solar walls to large solar
stations in deserts and intelligent solar innovations, car wash owners and
other companies can power their operations and reduce energy costs.
Living buildings
Planting of hanging gardens on open plan
buildings has been ongoing for some time. However, this technology is being
pushed further by architects and designers with more innovative concepts of
making entire buildings and cities green. Urban jungles also help absorb heat,
rainwater and carbon dioxide, as well as provide insulation.
Vertical farms
With the rapid growth of the global
population, providing enough food for all will be a problem soon, especially
when agricultural land is progressively limited by productivity and space. The
solution lies in vertical farms or indoor agriculture in densely populated
cities.
Windmill Farms
The wind is one of the most critical natural
energies available, therefore it represents a key area of attention in green
technology. Innovative wind turbines are now created with more attractive
designs, better durability in adverse weather conditions and better
functionality even in weak wind environments.
Biodegradable products
As the world comes to terms with the level of
damage that non-biodegradable products are causing to the environment,
biodegradable alternatives to plastic are part of future green technology
solutions that are expected to bring about changes. Manufacturers are currently
making efforts to produce safer products using biodegradable materials.
Green Computing
Eco-friendly computing is another example of
future green technology. With over 60% of system components ending up in
landfills, the focus is now shifting to more efficient and effective design,
manufacture, testing, use and disposal of computers and other related equipment
and devices to ensure minimal impact or null on the environment.
The future of green technology is bright, with
innovations that should change the way we do things, use everyday objects and
even interact with the surrounding environment.
LOOKING FORWARD
Companies have a wide range of ideas on how
green technology will transform over the next decade. Most agree that
innovations and implementation will increase. Some of the planned changes
include:
A significant increase in efficiency levels
over the next 5-10 years.
A completely new approach to building
innovation and the use of intelligent energy.
Continuous growth in consumer demand for
high-efficiency products.
Stricter implementation of measures to reduce
emissions.
Efficient designs that offer better
performance and are more sustainable.
Whichever way you choose to embrace green
technology in the future, you need to be at the forefront of energy efficiency
and emerging technologies to stay at the forefront. Your company or
organization must keep up with the latest efficiency standards and regulations,
as well as implementation requirements. In this way, you can quickly adapt to
future changes in green technology solutions.

The system on your home can be refreshing, but
with every new technology, it comes with new ways to ensure maintenance. While
it can be exciting to save money and provide a clean source of energy for you
and your family, how much does it cost to maintain these systems?
Once solar panels are installed, there are a
couple of factors to consider and some of them can be easily performed on their
own or outsourced to professionals.
Over the years, as solar panels are becoming
more popular, the cost of maintaining solar panels has dropped significantly
due to a better understanding of energy-generating panels. The general
maintenance of the solar panels is actually quite low and this is due to a
couple of factors:
First, solar panels don't have many moving
parts that reduce the risk of breakage and cracks and general wear and tear on
the equipment. That said, I'm out all day every day, from 40 degrees to winter
chills.
Dust and debris occasionally fall on the
panels over time, but usually, slip away due to the installation angle of the
panels, however, some of these particles can remain on the panels and obstruct
the rate at which sunlight is absorbed by the panels. This will result in a
general reduction in energy production.
Pro tip: most of this can be avoided by regularly checking the panels, removing any
particles with a simple soap and water solution. An easy way to monitor this is
from the comfort of your living room by occasionally checking the monitoring
software on your phone. The most modern systems allow the user to control the
average output for the day or week. If that output has been decreasing over the
course of a few months but the time is the same, you may need to clean the
system.
Before cleaning
Before doing this, however, check the
direction of the manufacturer for cleaning. Special instructions or warnings
for cleaning the panels may be present. Another thing to consider if you've
ever chosen do-it-yourself is to choose a nice day to clean your panels. The
panels may be too hot if you choose to clean it around noon. It is advisable to
clean it first in the morning or later in the evening.
In colder regions where snow often falls,
maintenance is also relatively easy as most of the snow that lands on the
panels will slip away due to the tilt of the panels or simply melt away from
the sun or the internal heat generated by the panels when they absorb sunlight.
However, it is still advisable to check the panels and manually remove any
excess snow.
Do-it-yourself or professional cleaner
Despite the do-it-yourself nature of most
maintenance, it is also advisable to occasionally request professional help to
verify solar panels, especially if the panels are installed on a very high roof
that is not easily accessible, these professionals can analyze and evaluate any
internal faults that may have occurred inside the solar panels. They can also
evaluate overall power and efficiency and advise you on how to ensure that
solar panels last for an even longer period.
In addition, when it comes to ensuring when
properly installed and maintained, solar panels can last up to 20 years. In
these 20 years, you would have cut your bills significantly, generated a large
amount of electricity and provided enough clean energy for the benefit of your
community.
How often should I clean my panels?
It is recommended to clean the panels once or
twice a year. Properly cleaned solar panels have been reported to result in up
to 3-5% higher efficiency. In addition, you can simply determine if your panels
need cleaning or maintenance if you check your power supply. If you notice that
there is a decrease in efficiency, it means that your panels need cleaning and
maintenance. If you choose to ignore it, there is a great chance that the life
of the panel will drastically decrease, so be sure to take the time to clean
and maintain the panels.
Conclusively, solar panel maintenance isn’t a
very expensive or difficult venture, as long as you follow simple guidelines,
then you can power their house efficiently for years without much stress.
Cost of maintenance of a solar system
Solar panel systems are simple and inexpensive
to maintain. In practice, you have to clean them every 6 - 12 months depending
on the climate or the region where you live. The cost will depend on whether
you choose to do the job alone or to go with a professional. The use of a
professional panel cleaner will cost around $ 225 for a 5 kWh system (16-20
panels) each time they go out to clean the panels.
Since you will need to do this every 6-12
months, you can calculate an average of around $ 350 per year for cleaning
costs. If you choose to do the job yourself, you're looking for $ 35 for a
special detergent (although most manufacturers suggest high-quality dishwasher
liquid) and other cleaning tools. They will cost around $ 125 as a one-time
purchase.
Conclusion
Solar panel systems are not difficult or
expensive to maintain. The biggest outlay is the initial purchase and
installation cost. The amount saved on energy production will significantly
offset the tiny system maintenance costs with clean light every year.
