Although there is no average size commercial solar system, prices start from Â£4000 + VAT for a 4kW setup made up of 16 panels & grid connection. Adding a Tesla battery storage system will store excess energy during the day when grid costs are higher, for use on-demand later in the day or night.
Average system costs = $95 per square foot. Average solar panel output = 10.6 watts per square foot. Average solar energy system costs = $8.95 per watt. In order to compare the solar energy costs to conventional hydrocarbon fuels, we must covert the $8.95 per into KWH.he $9,000 per KW for solar is not very helpful in comparing electric generation costs to other fuels like coal or gas. Since coal, oil, and gas can be measured on a cost per KWH, we should measure solar costs on a KWH basis.
