Why New Mexico lands where it does
New Mexico sits near the middle on electricity price at 14.6 cents a kilowatt-hour, so payback is driven about equally by the rate and by the 6.3 peak sun hours the state averages.
The sunshine genuinely helps: 6.3 peak sun hours a day is among the best in the country, so a given system produces noticeably more here than the same panels further north.
Local and utility incentives are not included above, because they change too often for any published list to stay right. If New Mexico offers a rebate, enter it in the calculator and the payback will shorten accordingly.
