High summer air conditioning bills are a reality in Alief. While rooftop solar is a powerful way to generate your own electricity, the rules in Texas's deregulated market have changed the financial equation. Sending surplus solar power back to the grid often yields very little credit. This makes how you use your solar energy—not just how much you produce—the key to maximizing savings in 2026.

Estimated Solar System Costs in Alief (2026)
Costs for a professionally installed rooftop solar system are based on its size, measured in kilowatts (kW). For an average home in the Alief area, here are two modeled scenarios:
- Solar Panels Only (12.4 kW): The estimated gross cost is around $31,000. This system is sized to cover a significant portion of a typical household's electricity usage.
- Solar Panels + Battery (12.4 kW system with 10 kWh battery): The estimated combined cost is around $46,000. Adding a battery allows you to store solar energy for use at night or during an outage, which significantly improves the system's financial return.
These figures are modeled estimates. Your final cost will depend on your specific home, equipment choices, and installer.
Incentives & Tax Credits
Key Texas Solar Incentive: Property Tax Exemption
As of early 2026, the long-standing 30% federal tax credit for residential solar is no longer available for systems placed in service this year. This makes state and local benefits more important than ever.
The most significant financial incentive for Texas homeowners is the 100% property tax exemption for the value added by a solar energy system. When you install solar panels, your home's value may increase, but thanks to this exemption, your property tax bill won't. You can claim this benefit by filing Form 50-123 with your county appraisal district.
There is no state income tax in Texas, so there are no state tax credits for solar. The primary financial benefits come from bill savings and the property tax exemption.
Net Metering: Address-specific utility or retail electricity plan
Limited Export Credit
Optional
Understanding Export Rates in Alief
Texas does not have a statewide net metering law that requires utilities to credit you at the full retail rate for surplus solar energy. Instead, your compensation depends entirely on the buyback plan offered by your Retail Electricity Provider (REP).
Most REP buyback plans pay a low, wholesale-based rate for your exported power. Our model uses a conservative estimate of $0.0397 per kWh for exported energy—far less than the $0.1587 per kWh it costs to buy that same energy from the grid. This is why using your solar power onsite or storing it in a battery is financially superior to exporting it.
Projected Savings
How Solar Creates Value in the Texas Market
With an average electricity rate of $0.16/kWh from your retail provider, every kilowatt-hour of solar energy you use directly in your home is a kilowatt-hour you don't have to buy. This is called self-consumption, and it's where the primary value of solar lies in Texas.
A 12.4 kW solar-only system in Alief is modeled to save approximately $1,476 annually, leading to a payback period of about 18.2 years. However, by adding a battery, you can store excess daytime energy instead of exporting it for a low credit. This increases your self-consumption and your savings.
The same 12.4 kW system paired with a 10 kWh battery is modeled to generate $2,379 in annual savings, shortening the payback period to just 15.4 years. The battery also provides valuable backup power during grid outages, a growing concern for many in the ERCOT service area. An owned solar system can also be a compelling feature for future homebuyers, potentially supporting your home's resale appeal.
