Future Green Technology Solar FAQ
Q1:
Does a PV system produce electricity all the time?
A1:
No. A PV system typically generates power from approximately 8 a.m. to 6 p.m., with peak output occurring between noon and 1 p.m. when solar irradiance is strongest. During non-production hours, your home or business draws power from the grid. Future Green Technology designs systems to maximize this daily production window through optimal panel placement and efficient component selection.
Q2:
Can PV systems produce power on cloudy days?
A2:
Yes, but at a reduced capacity. On overcast days, a PV system may receive only 5–10% of typical sunlight, proportionally lowering its output. FG Technology utilizes high-efficiency monocrystalline panels that perform better in low-light conditions compared to standard panels, ensuring more consistent energy harvest.
Q3:
Do cold temperatures impact PV systems?
A3:
Interestingly, PV systems operate more efficiently in cooler temperatures. Reduced output in winter is primarily due to shorter daylight hours and lower sun angles, not the cold. Future Green's panels are rated for extreme temperature ranges and maintain reliable performance year-round.
Q4:
What factors impact the performance of my solar system?
A4:
Several key factors influence system efficiency:
Shading from trees or structures
Panel orientation and tilt angle
Daily sunlight hours at your location
Inverter quality and technology
Ambient temperature
A professional FG Technology site assessment evaluates all these variables to design a system optimized for your specific conditions.
Q5:
How much roof space is required for a solar system?
A5:
Space needs depend on system size and panel specs. For example, using Future Green's high-efficiency 620W panels (2.38m x 1.13m), a 5kW system requires approximately 21m² of south- or southwest-facing roof space, plus additional area for fire safety clearance. Our designers create detailed layouts to maximize production within your available space.
Q6:
How long does a typical solar system last?
A6:
A well-maintained solar system can last 25–30 years. While panels may gradually lose efficiency over time, they continue producing energy beyond this period. FG Technology uses tier-1 panels with industry-leading degradation rates, and our inverters typically require one replacement during the system's lifespan due to their 10–12-year service life.
Q7:
What type of warranty is provided with my system?
A7:
Future Green systems come with comprehensive protection:
Panel Performance Warranty: 25–30 years (guarantees 80–90% output at the end of the term)
Panel Product Warranty: 10–12 years against manufacturing defects
Inverter Warranty: 5–10 years (extendable)
Battery Warranty: 5–10 years, depending on technology
Workmanship Warranty: 2–5 years on installation quality
All warranties are fully documented and backed by FG Technology's ongoing support commitment.
Solar System characteristic:
1. All Systems have LCD digital display which allows you to see the system working, (eg) Charge data, System voltage, Daily power consumption and temperature.
2. All type of BPS system both has AC and DC output.
3. All system have automatic switch , If mains power goes off the system will switch automatically over to battery power, When mains power resumes
the system will switch back automatically. The batteries will resume recharging automatically.
4. All inverters are Pure Sine Wave inverters. This allows the use of Air Conditioners and refrigerators without any problem.
5. Each component has a single chip detector. Assembled by the IPM or IGBT of Mitsubishi
This protects the system from Overloads, Low Voltage and Under Voltage (alarm) Over Heating, Short circuit, Reverse Polarity.
6. Your system can be updated very easily. Just by adding extra components your system will increase power capacity.
7. Battery optional, you can purchase from us or locally.
8. Simple to install, just follow installation instructions.
9. Our System offers Cutting Edge Technology, State of the Art Quality with Greater Functionality than our competitors, at Competitive prices.
