How to compare solar quotes
Solar prices in Oklahoma have decreased 42% over the last decade.
Most installers set the price according to the system’s wattage. Similar to “cost per square foot” when buying a house, “cost per watt” allows you to compare the relative value of a solar panel system. It shows you the per-dollar price of your system’s energy production potential.
Get quotes from at least three to four different solar companies in Oklahoma. Make sure the estimated price includes all the equipment you want, labor, permits and grid hookup. Watch for hidden fees for system monitoring or maintenance service charges.
| Statewide | Oklahoma City | Tulsa | |
|---|---|---|---|
| Average cost per watt | $2.36 | $2.37 | $2.37 |
Solar panel installation cost factors in Oklahoma
How much you pay to go solar largely depends on the size of your system, the equipment you want and the condition of your roof. Local permits and fees are a small part of your overall costs.
Size of your system
A typical Oklahoma household needs about a 7 kW system, which costs $16,520 on average. Depending on your energy needs, you might need a smaller or larger system.
How to estimate what system size you need: First, look at your electric bill. It should say how many kilowatt-hours (kWh) you used last year. Then, divide that number by 1,200 to estimate your system size in kilowatts (kW).
For example, if you used 12,000 kWh of electricity last year, you would need a 10-kW system. If you used 10,800 kWh, you would need a 9-kW system.
Pro tip
Upgrade old appliances with more eco-friendly ones before you go solar. If you use less electricity, you need fewer solar panels, making the whole system more cost-effective.

Solar equipment
The equipment — panels, inverters, mounting hardware and other electrical accessories — is typically the largest portion of your overall solar costs (approximately 25% to 50%).
- Solar panels: Prices vary by efficiency rating. In general, monocrystalline panels are considered the best value. Cheaper solar panels are typically polycrystalline.
- Solar batteries: Solar battery costs generally range from $7,000 to $18,000. Batteries store any excess energy your panels produce during the day, allowing you to keep your lights on at night. Without a battery, that unused clean energy goes to the power grid, and you’ll still depend on utility power after dark.
- Solar inverters: Inverters convert solar power from direct current (DC) to alternating current (AC). Inverter costs typically range from $1,000 to $3,000.
- Monitoring system: Some companies include a solar monitoring system to track energy production and identify potential issues. If not, you can buy a standalone system for $80 to $400.
Condition of your roof
High-quality solar panels last 25 to 30 years, and your roof needs to last just as long.
ConsumerAffairs often hears from customers who were blindsided by expensive roof repairs discovered after their solar panels were already installed. This is a frustrating and expensive process — avoid it if you can.
To ensure a seamless and cost-effective solar journey, your roof must match the system's longevity. Get your roof inspected, fixed or replaced before you go solar.
Pro tip
If you have an electric car, ask about EV charger options. Homeowners in more rural parts of Oklahoma should also consider critter guards to protect the panels.

Are solar panels worth it in Oklahoma?
Going solar is often worth it for many Oklahoma homeowners for the long-term savings on utility bills. Over 25 years, residents with solar panels avoid $29,807 in utility costs on average.
Solar panels typically save $20,000 to $90,000 over 25 years.
Switching to solar can lower your monthly energy costs. For example, Lowell in Oklahoma City said his electric bill dropped from about $125 to around $15 after installing solar. He financed his system with a five-year loan at $175 per month.
When people are unhappy with solar, the issue is often with the installer. For example, Tasha in Okmulgee said she experienced delays and problems from the start, and now worries she’ll be paying for panels she hasn’t been able to use.
Regional solar considerations in Oklahoma
Whether solar is worth it also depends on where you live in Oklahoma. The state only gets 4.5 to 5.5 peak sun hours daily. Lots of shading — like tall trees above your roof — will make your solar system less efficient. Since solar panels generate more power with more sunlight, this can affect the financial returns on your investment.
It’s still worth considering if you like the idea of a cheaper monthly energy bill. We suggest using the National Renewable Energy Laboratory (NREL) PVWatts Calculator to estimate how much electricity a solar panel can produce over a year on your house.
| Statewide | Oklahoma City | Tulsa | |
|---|---|---|---|
| Typical installation cost | $16,520 | $16,590 | $16,590 |
| Payback period | 15.1 years | 16.98 years | 11.88 years |
| Utility costs avoided over 25 years | $29,807 | $20,025 | $41,184 |

How can I pay for solar panels in Oklahoma?
Financing options and leasing programs make solar more affordable for Oklahoma homeowners. In an ideal scenario, your solar power system generates enough extra power to cancel out your monthly payment.
- Solar financing: A solar loan works like any other home improvement loan. There’s an application and approval process. You pay it back over time (with interest) each month.
- Solar leases: Leasing solar panels lets you set up a system without high upfront costs. A solar company installs and maintains the panels on your property, and you pay a monthly fee to use them.

Solar incentives in Oklahoma
Many states offer rebates or tax credits that lower the cost of installing solar panels, but Oklahoma currently does not. There are no statewide incentives for homeowners to install solar panels.
As of 2026, the federal solar tax credit has also been phased out for new residential systems, meaning most Oklahoma homeowners pay the full installation cost.
However, some utility efficiency programs and financing options may still help reduce overall energy costs. Read our guide to Oklahoma’s solar incentives to learn more.

FAQ
Can I get free solar panels in Oklahoma?
We are not aware of any legitimate programs for free solar panels in Oklahoma. However, you can lease a solar energy system with little to no upfront costs. Just look out for scams that promise free solar panels — they can end up costing you quite a bit of money.

Is it cheaper if I install solar panels myself?
It’s potentially cheaper but also difficult and dangerous. This is especially true if you don’t know what you’re doing during a large residential project.

How does net metering work in Oklahoma?
Net metering is when you sell surplus solar energy to your local electric company. In Oklahoma, electric providers issue a credit on your electricity bill as compensation. To be eligible, your system needs to be under 300 kW, which typically isn't an issue as most residential systems are considerably smaller.
What is the difference between monocrystalline and polycrystalline solar panels?
The difference between monocrystalline and polycrystalline comes down to efficiency and materials: monocrystalline panels are made from pure, single silicon crystals, whereas polycrystalline panels are made from various silicon fragments melted together. Both are types of photovoltaic (PV) solar panels.
Are solar panels expensive to maintain?
No, solar panels have relatively low maintenance costs. If you clean the solar panels yourself, the only maintenance cost will be the water used to hose them down. Hiring a professional to clean your solar panels typically costs $100 to $350.
How do solar batteries work?
Solar panels only generate electricity when the sun is shining. A solar battery stores the extra energy your panels produce during the day so you can use it at night or during a power outage.
Without a battery, that unused energy goes to the grid, and you’ll still depend on utility power after dark.
