Solar in Toledo: common questions

Are solar panels worth it in Toledo, OH?

For an example 7 kW system costing $21,000 on a home using 10,500 kWh a year, payback in Toledo is 11.2 years with full net metering and 14.9 years if exports earn half the retail rate, at the Ohio average price of 19.45¢/kWh (EIA, July 2026).

How much electricity do solar panels produce in Toledo?

About 1,304 kWh per year for each kW of south-facing panels at a 20° pitch (NLR PVWatts, typical-year weather), from 56 kWh in Dec to 150 kWh in Jul.

What size solar system does a home in Toledo need?

About 8.1 kW to cover 10,500 kWh a year. Divide your own annual use by 1,304 kWh per kW for a first estimate; if exports earn less than retail, a smaller system often pays back faster.

Does roof direction matter in Toledo?

Yes. Per kW at a 20° pitch: south 1,304 kWh, southeast 1,262 kWh, southwest 1,243 kWh, east 1,138 kWh, west 1,113 kWh, east-west (split) 1,125 kWh a year. South-facing roofs produce the most; east or west roofs still work, with less output.
