solar panel cost per kw
solar panels?
The best solar panels available today are about 13% efficiency in converting sunlight into electricity. A typical house will use about 40. kWh of electricity per day (1 kWh = 1 hour killowatt, 1 kW = 1000 J / s). Assuming 8.0 hours of useful sunlight per day, calculate the minimum of solar panel surface necessary to provide all of a typical home electricity (The sun supplies energy at a rate of about of 1.0 kilowatts per square meter of land) costs approximately $ 24,000 to install a solar panel and battery kit of 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?
6000 days = A little less than 16 ½ years, which is exactly why you do not see millions of these installed all over the place – too expensive to be profitable and that is no maintenance costs.
