Since most panels have a capacity of 300 watts, a 1000kW system would require 3333 or more solar panels to reach its intended capacity..
Since most panels have a capacity of 300 watts, a 1000kW system would require 3333 or more solar panels to reach its intended capacity..
If you use small 100W solar panels, you will need 90 solar panels to produce 1,000 kWh per month. Most homeowners use standard 300W solar panels; you’ll need 30 solar panels..
Monthly electricity usage ÷ monthly peak sun hours x 1000 ÷ power rating of solar panel. 1000kWh ÷ 160 hours x 1000 = 6250 ÷ 400W = 15,62 Solar panels are needed for 1000kWh..
To find out how many panels are needed to generate 1000 kWh/month, divide your target (1000 kWh) by the amount one panel can generate (37.5 kWh): 1000 kWh / 37.5 kWh = approximately 27 panels [pdf]
