Is solar worth it in Oklahoma in 2026?
With an average electricity rate of 11.5¢ per kWh and 5.3 peak sun hours per day, Oklahoma homeowners are in an excellent position to benefit from solar panels. A typical 9kW system will produce around 13,928 kWh per year — enough to offset a significant portion of a typical Oklahoma home's electricity usage.
At current electricity rates, that production saves approximately $1,601 per year. Over 25 years — the standard panel warranty period — the projected net profit after recouping the system cost is around $21,125.
How much do solar panels cost in Oklahoma?

| Cost item | Amount |
|---|---|
| System cost (9kW) | $27,000 |
| Federal 30% ITC | −$8,100 |
| Oklahoma does not offer a state solar incentive program. Oklahoma's relatively low electricity rates and natural gas prevalence have historically limited solar adoption compared to other states. Net metering is available through Oklahoma Gas & Electric and other utilities. The federal 30% ITC applies. | Additional savings |
| Net cost (after federal ITC) | $18,900 |
Actual costs vary by installer. Always get at least 3 quotes. Installer labour, roof type and system complexity affect final pricing.

What affects solar savings in Oklahoma?
Every homeowner's solar savings are different. In Oklahoma, the key variables are:
- Electricity rate (11.5¢/kWh): Oklahoma's electricity rate is near the national average. Combined with sun hours and system size, this gives a typical homeowner a solid case for solar investment.
- Peak sun hours (5.3 hrs/day): Oklahoma's solar resource is solid — comparable to Germany, which has one of the highest solar adoption rates in the world. Year-round production will be consistent.
- System size (9kW typical): The right size depends on your electricity bill. A $150/month bill typically requires a 6–8kW system to offset 80–100%. Use our System Size Calculator to find your exact target.
- Roof type and orientation: South-facing roofs at 30° pitch are ideal. West-facing roofs produce 15–20% less but may generate more electricity during peak-price afternoon hours, improving time-of-use savings.
