A solar energy system big enough to power a computer and a few other small items might cost you about $700 to $1000. These are also well suited for RVs, boats and camping. Learn more about portable solar energy units.
at $ 45000 a solar energy system equates to $ 9000 a kilowatt the $ 9000 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 basisverage 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
