Utility-scale solar costing seven cents is a big waste of money. Rooftop solar costing 30 cents is insane. Special interests – the solar industry and environmentalist crackpots – have convinced legislatures and public utility commissions to stack the deck with net metering and absurdly high tiered electric rates. The result is to make it profitable for homeowners to invest in what otherwise would be very expensive electricity. Society as a whole pays for the economic waste, amounting typically to 28 cents per kilowatt-hour of rooftop electricity.
Here is an example of rooftop solar that costs 30 cents a kilowatt-hour. A 5-kilowatt rooftop system costs about $21,000 installed. It will generate 7,000 kilowatt-hours per year. If it is financed over 20 years at 8% interest, the annual payment will be $2,139. The cost per kilowatt-hour is $2,139/7,000 = $0.306, or 30.6 cents per kilowatt-hour. Of course, costs and interest rates vary, as does sunshine. If you think 8% is too high for the interest rate, ask yourself if you would loan your neighbor $21,000 for 20 years for less. Rooftop solar is expensive compared to utility-scale solar, because it is a small custom installation. The orientation and slope of the house roof may be less than ideal. Large-scale utility solar, in contrast, can be as cheap as seven cents per kilowatt-hour.
