Solar in Oklahoma: is it worth it in 2026?
Oklahoma is a slow-payback state: solar works, but it takes well over a decade to earn back what you paid. Three things decide that: electricity here is among the cheapest in the country (42nd most expensive of 51), it gets more sun than most states (7th), and exported power earns retail credit within each month, with leftovers paid less. Of the 51 states and DC, Oklahoma has the 23rd-fastest payback for a typical home.
The average home here pays about $141 a month for 1,064 kWh. A 7.5 kW system sized for that home would knock about $1,390 off the first year's bills, 82% of the total.

What makes solar pay off in Oklahoma
- Size the system to cover your yearly use. With monthly netting, power you export is worth nearly as much as power you use, so aim for little leftover each month.
- Cheap power stretches payback. At 13.2¢ per kWh, the price you pay matters more than anything. At $3.34 per watt, the high end of what companies quote, payback for a typical system here stretches to 17 years.
- Lots of sun. Each kW of panels makes about 1,542 kWh a year here, so a smaller system covers more of your bill than in most states.
Payback by system size
An average Oklahoma home uses about 12,768 kWh a year. Here's how systems sized to cover part or all of that work out, bought with cash at $2.57 per watt:
| Covers | Size | Price | Makes a year | Payback | 25-year savings |
|---|---|---|---|---|---|
| 48% | 4 kW | $10,280 | 6,168 kWh | 16 years | $10,807 |
| 72% | 6 kW | $15,420 | 9,252 kWh | 15 years | $17,523 |
| 103% | 8.5 kW | $21,845 | 13,107 kWh | 14 years | $25,822 |
| 127% | 10.5 kW | $26,985 | 16,191 kWh | 16 years | $25,514 |
The 8.5 kW system has both the fastest payback and the most savings. Assumes exported power earns about 85% of the retail rate, prices rise 2.5% a year and one inverter replacement.
How Oklahoma credits power you send to the grid
Monthly netting
Net metering with excess power credited at the utility's avoided-cost rate.
We haven't found a single published export rate for Oklahoma, so the calculators assume about 85% of the retail rate. Ask your utility for its rate and enter it.
By utility
- OG&E: Net metering with excess power credited at OG&E's avoided-cost rate.
Before you sign in Oklahoma
Check the license. Look the company up with the Oklahoma Construction Industries Board, by its legal name or license number, and ask for the electrician's license number too.
Oklahoma has no solar-specific sales law that we know of, so its general consumer protection law applies.
In every state, the FTC Cooling-Off Rule lets you cancel a contract signed at your home until midnight of the third business day.

Questions about solar in Oklahoma
How long does solar take to pay for itself in Oklahoma?
About 14 years for a typical 7.5 kW system bought with cash at the 2026 median price of $2.57 per watt, with no federal tax credit and one inverter replacement. A bigger or smaller system, a different price, or your own usage will change that; the table above shows other sizes.
Does Oklahoma have net metering?
Partly. Net metering with excess power credited at the utility's avoided-cost rate.
Is there a solar tax credit in Oklahoma in 2026?
Not from the federal government for buyers: the 30% homeowner credit ended for systems installed after December 31, 2025. For a typical 7.5 kW system in Oklahoma, that credit was worth about $5,783 and brought payback down to 9 years, instead of 14 years now. Leasing companies can still claim a business credit, so ask for a lease or PPA price too. Your state energy office lists any state rebates.
Is a solar battery worth it in Oklahoma?
On bill savings alone, not quite: a 13.5 kWh battery at about $15,650 would move about 3,548 kWh of solar power a year from the grid to your evenings in a typical Oklahoma home, adding about $403 of savings over 15 years. That doesn't cover its price, so the system's payback goes from 14 years to 22 years; the rest is paying for backup during outages. Time-of-use rates, battery rebates and utility payments for sharing your battery can tip it; try your numbers in the payback calculator.
Is plug-in solar legal in Oklahoma?
There's no plug-in solar law yet in Oklahoma, so your utility may treat a kit like any rooftop system.
How do I check a solar company's license in Oklahoma?
Look the company up with the Oklahoma Construction Industries Board (oklahoma.gov/cib.html) by its legal name or license number, and ask for the electrician's license too.
