Solar panels in Oklahoma: savings by city
Oklahoma’s average residential electricity price for January to August 2026 was 13.81¢ per kWh, 4.38¢ below the US average of 18.19¢ (EIA).
Panels in the 6 cities we cover here produce an average of 1,547 kWh per kW a year, 2% more than the average of the 400 US cities in our data (1,517 kWh). Oklahoma City gets the most sun of the cities listed below (1,574 kWh per kW) and Tulsa the least (1,499 kWh). For an average US home, that is the difference between a 6.9 kW and a 7.2 kW system to cover a year’s use.
At this price, a system that covers an average US home’s use (10,788 kWh a year) saves about $1,490 in its first year anywhere in Oklahoma. Sunnier cities need a smaller system to do it, so it costs less at any price per watt.
