A 20kW Solar Kit requires up to 1,500 square feet of space. 20kW or 20 kilowatts is 20,000 watts of DC direct current power. This could produce an estimated 1,300 to 3,000 kilowatt hours (kWh) of alternating current (AC) power per month, assuming at least 5 sun hours per day with the solar array facing South. The highest output will be achieved with an unobstructed south-facing view of the sun for maximum solar power. The actual power generated will vary based on location, equipment and installation factors. Refer to your electric utility bill to find the actual kWh used per month and compare it to how much power these low cost 20kW PV systems can generate.
