Why Michigan lands where it does
Michigan sits near the middle on electricity price at 18.9 cents a kilowatt-hour, so payback is driven about equally by the rate and by the 4 peak sun hours the state averages.
At 4 peak sun hours a day Michigan is on the low side, so systems here need to be larger than a southern equivalent to produce the same amount.
Local and utility incentives are not included above, because they change too often for any published list to stay right. If Michigan offers a rebate, enter it in the calculator and the payback will shorten accordingly.
