Frequently Asked Questions
What is the environmental derating factor?
The environmental derating factor accounts for real-world losses from dust, heat, and weather, so panels rarely produce their full rated output in practice.
What wattage is needed for 10,000 kWh a year with 4.5 sun hours and full bill offset?
At an 85 percent derating factor, this requires a solar system of about 7,163 watts.
Why does sun hours per day matter so much?
Sun hours represent the average daily peak sunlight a location receives, so locations with fewer sun hours need a larger system to produce the same total energy.
