Solar in Oklahoma: Plenty of Sun, Limited Incentives

Oklahoma has more in common with Texas than most people realize when it comes to solar. You get excellent sunshine — 4.8 to 5.5 peak sun hours per day across most of the state. You have no state income tax credit for solar. And you have a utility landscape that is not exactly rolling out the welcome mat for rooftop solar.

But Oklahoma also has some things working in its favor: low installation costs, decent sun, and electricity rates that have been creeping upward. The question for Oklahoma homeowners in 2026 is whether the production advantage is enough to overcome the incentive gap. Let us look at the real numbers.

The Good News

Strong Solar Resource

Oklahoma averages 4.8 to 5.5 peak sun hours per day, with the western part of the state getting the most. Oklahoma City sits around 5.0 hours, and Tulsa around 4.8. This is solidly above the national average.

More sun means more production. An 8 kW system in Oklahoma City will produce roughly 12,000-13,000 kWh per year — enough to offset most of a typical household's consumption.

Low Installation Costs

Oklahoma's installation costs are among the lowest in the country at $2.40-$2.80 per watt. Lower labor costs and simpler permitting keep prices down. A 7.5 kW system typically runs $18,000-$21,000 before incentives.

In a post-ITC world where you are paying full price, that lower starting cost makes a significant difference in payback calculations.

Property Tax Exemption

Oklahoma exempts the added value of solar energy systems from property tax assessment for five years. After year five, the value is added to your assessment. This is a partial benefit — not as strong as states with permanent exemptions — but it helps during the early payback period.

Growing Installer Market

Oklahoma's solar market has grown steadily, and several regional and national installers now serve the state. This means better competition and more choices than homeowners had even a few years ago.

The Challenges

No State Tax Credit or Rebate

Oklahoma eliminated its state solar tax credit in 2015. There is no cash rebate. There is no SREC market. With the federal ITC expired, Oklahoma homeowners have essentially no direct financial incentive to install solar beyond the temporary property tax exemption.

This is the biggest obstacle. You are paying the full system cost with no credits to soften the blow.

Weak Net Metering

This is where Oklahoma gets tricky. OG&E (Oklahoma Gas & Electric) and PSO (Public Service Company of Oklahoma) offer net metering, but the terms are less favorable than in many states. OG&E credits excess generation at the avoided cost rate — roughly $0.03-$0.05/kWh — rather than the full retail rate.

That is a massive difference. If you use a kWh from your panels directly, you save $0.12-$0.14 in avoided utility costs. If you export that same kWh to the grid, you get credited $0.04. This means self-consumption is critical in Oklahoma. You want to use as much of your solar production as possible during the day and export as little as possible.

Severe Weather

Oklahoma is tornado alley. While modern solar panels are rated for high winds (up to 140-160 mph), tornadoes can exceed those thresholds. More common damage comes from hail — Oklahoma gets some of the worst hail storms in the country.

Most quality solar panels are rated for 1-inch hail at 50+ mph. Larger hail can cause damage. Insurance typically covers solar panels under your homeowner's policy, but confirm coverage and deductibles with your insurer before installation.

The Oklahoma Solar Math (2026)

Typical 7.5 kW system:

• Installed cost: $19,500 ($2.60/watt)
• Federal ITC: $0 (expired January 1, 2026)
• State credits: $0
• Net cost: ~$19,500

Annual production: ~11,250 kWh

Self-consumed (70%): 7,875 kWh x $0.13 = $1,024

Exported (30%): 3,375 kWh x $0.04 = $135

Annual savings: ~$1,159

Payback period: ~16.8 years

25-year savings: $12,000-$20,000 (assuming 3-4% annual rate increases)

The weak net metering drags the payback out. If you can increase self-consumption to 85% (by running appliances during peak solar hours or adding a battery), annual savings jump to roughly $1,300 and payback drops to 15 years. Still long, but improved.

If you are considering a battery to boost self-consumption, the Tesla Powerwall is one of the most widely available options in Oklahoma and pairs well with rooftop solar for maximizing the electricity you keep rather than export at avoided-cost rates.

Since Oklahoma has no incentives to fall back on, getting the lowest per-watt price matters more here than almost anywhere. Comparing quotes from multiple installers is essential.

When Solar Makes Sense

Install if:

• You have high daytime electricity usage or can shift usage to solar hours
• Your monthly bill exceeds $140
• You plan to stay in your home 12+ years
• You are motivated by energy independence beyond pure ROI
• You are willing to pair solar with a battery for self-consumption optimization

Wait or skip if:

• Your electricity bill is under $100/month
• You rely on net metering credit for the economics to work (they will not at avoided cost rates)
• You plan to move within 7 years
• You are in a high-hail-risk area and your insurance does not cover solar panels

Key Takeaways

• Oklahoma has excellent sun — 4.8 to 5.5 peak hours daily
• No state tax credit or rebate means you pay the full installed cost
• Net metering credits at avoided cost ($0.03-$0.05/kWh) make self-consumption critical
• Low installation costs ($2.40-$2.80/watt) are the biggest advantage
• Maximize daytime usage of your solar production — export as little as possible
• Typical payback: 15-17 years depending on self-consumption ratio
• Hail and severe weather are real risks — confirm insurance coverage
• A battery makes more economic sense in Oklahoma than in states with full retail net metering

Oklahoma solar is an uphill economic battle in 2026 without federal or state incentives and with weak net metering. But if you have high usage, can optimize self-consumption, and plan to stay long-term, the combination of great sun and low installation costs can still produce a positive return. Just go in with realistic expectations about the timeline.
