Why Maryland lands where it does
Maryland sits near the middle on electricity price at 17.9 cents a kilowatt-hour, so payback is driven about equally by the rate and by the 4.4 peak sun hours the state averages.
At 4.4 peak sun hours a day, production is close to the national average.
Local and utility incentives are not included above, because they change too often for any published list to stay right. If Maryland offers a rebate, enter it in the calculator and the payback will shorten accordingly.
