How many solar panels do you need to provide the energy needed to maintain your home and family? This is a big question as it directly affects the cost of your new solar energy system. Even if the prices of solar panels have dropped in recent years, you still don't want to overpay.
Check how much you've paid and your energy usage (kWh).
Consider how your needs will evolve in 10-20 years.
Define a solar energy production objective.
Review your goal with excess energy in mind.
Divide monthly electrical consumption by 30 days.
Calculate the power of your solar energy system.
Get a solar quote for the ideal size of your system.
Find the number of panels for the power you need.
Do not know how to choose a solar panel? Hope this list can be a good buying guide. You should always remember that a solar panel system is a long-term investment, so there are many things beyond the price you should consider.
Consider both upfront cost and long-term value.
Look for reputable manufacturers with good warranties.
Higher efficiency means more power per square meter.
How well panels perform in high temperatures.
Panels should withstand weather conditions for 25+ years.
Ensure panels fit your available roof space.
Monocrystalline, polycrystalline, or thin-film.
According to the roof area, the installed capacity is generally 375 watts per component. The component specifications are: 1940mm long and 992mm wide. We estimate how much photovoltaic system can be installed on the roof of the house. It can be calculated according to the following formula:
Installed capacity = 120 watts / square meter × roof area
Installed capacity = 180 watts / square meter × roof area
Installed capacity = 130 watt / square meter × (yard length × 5 meters)
For example: The fixed installation in Hunan, China is calculated according to the annual number of generation 1460 hours; the active tracking and installation at different time intervals is calculated according to the annual number of generation 1890 hours.
Based on this, you can estimate how much capacity can be installed on your roof, and how much electricity can be generated by a home solar photovoltaic power station.
This is just an overview of the installation and is not meant to be a complete guide. All systems are different, there is no set of instructions that can be used to cover all options and configurations. Do not attempt to install your own solar system if you are not comfortable working with electricity and tools.
An off-grid solar electric system involves working with both alternating current (AC) and direct current (DC) voltages. These voltages can be lethal if all safety precautions are not followed.
Grid-based systems are solar photovoltaic systems that generate electricity only when the public grid is available. They must connect to the grid to work. They can return excess electricity generated to the grid when you produce too much, which allows you to credit it for future use.
These systems allow you to store your solar energy in batteries for use when the network goes down or you are not on the network. Hybrid systems provide the energy needed to compensate for grid energy when the sun is shining and will even send extra energy to the grid for credit for later use.
Batteries used in household energy storage are usually made from one of three chemical components: lead-acid, lithium-ion and brine. In most cases, lead-acid batteries are the best choice for solar panel systems, although other battery types can be more affordable.
Lead-acid batteries are a tried-and-tested technology that has been used in off-grid energy systems for decades. They offer reliability and are often more cost-effective for large installations.
Most new home energy storage technologies use lithium-ion chemistry. Lithium-ion batteries are lighter, more compact, and have a longer lifespan than lead-acid batteries.
A newer technology in home energy storage is saltwater batteries. Unlike other options, brine batteries do not contain heavy metals and rely instead on brine electrolytes, making them more environmentally friendly.
