Now, by average solar panel wattage per square foot, we can put a 10.35kW solar system on an 800 sq ft roof. This is how many solar panels you can put on this roof: If you only use 100-watt solar panels, you can put 103 100-watt solar panels on the roof. If you only use 300-watt solar panels, you can put 34 100-watt solar panels on the roof.
1 kWp solar panel size. If you wanted to run a solar system with a panel output of 1 kWP, you''d need 1 kilowatt of power. 1 kilowatt would be the peak capability of your panels on a day with full sun, which is 1,000-watts. Solar panels usually come in 200-350 watt units, although some higher power panels are available too.
Radiation data for solar electric (photovoltaic) systems are often represented as kilowatt-hours per square meter ...
