Solar Panel Kw Rating

solar pannels?
The best solar panels currently available are about 13% efficient in converting sunlight to electricity. A typical home will use about 40. kWh of electricity a day (1 kWh = 1 killowatt hour; 1 kW = 1000 J/s). Assuming 8.0 hours of useful sunlight per day, calculate the minimum solar panel surface area necessary to provide all of a typical home’s electricity (The sun supplies energy at the rate of about 1.0 kilowatts per square meter of earth )
It costs approximately $24,000 to install a solar panel and battery kit this size with a 20 year warranty. If electricity costs continue to average $0.10 per kilowatt hour for the next 20 years, how many years will it take for such a system to pay for itself?
6,000 days = Just under 16 and a half years
Which is exactly why you don’t see millions of these installed all over the place – too expensive to be cost effective and that is without any maintenance costs.
