Midlothian Solar Panel & Battery Costs in 2026
To get real value in Texas's deregulated market, a solar and battery system is the standard recommendation. While a solar-only installation is cheaper upfront, its financial return is severely limited by low buyback rates from most Retail Electric Providers (REPs).
- Solar + Battery System (Recommended): The average gross cost is around $23,500. After applying the 30% federal tax credit, the net cost drops to approximately $16,450. This setup allows you to store your own power, giving you independence from ERCOT and your REP.
- Solar-Only System (Basic Option): This system costs about $11,500 before incentives, or $8,050 after the federal tax credit. It's a lower initial investment but means you'll sell your valuable excess energy back to the grid for pennies on the dollar.
Incentives & Tax Credits
Available Solar Incentives for Midlothian
Texans benefit from some excellent incentives that make going solar much more affordable. These financial tools are key to lowering your upfront cost and speeding up your return on investment.
- Federal Solar Tax Credit: This is the most significant incentive. You can claim 30% of your total system cost (including the battery) as a credit on your federal taxes. For a $23,500 system, that’s a $7,050 credit.
- Texas Property Tax Exemption: Installing solar increases your home's value, but thanks to state law, your property taxes won't go up a single dollar because of it.
- Texas Sales Tax Exemption: All solar energy equipment is 100% exempt from state and local sales tax, saving you hundreds of dollars on the initial purchase.

Understanding Solar Buyback in the Texas Market
Texas doesn't have a statewide net metering law. Instead, your ability to sell back excess power depends entirely on the 'Solar Buyback Plan' offered by your Retail Electric Provider (REP). Companies like TXU Energy, Reliant, and others have plans, but they often credit you at a wholesale rate, which is far less than the retail rate you pay. This is precisely why pairing solar panels with a battery is so critical in Midlothian. Storing your own energy is almost always more valuable than selling it back to the grid.
Projected Savings
Potential Electricity Bill Savings
Midlothian households with an average $140 monthly electric bill can expect significant savings. A properly sized solar and battery system can offset nearly 100% of your electricity usage. By storing your excess solar power in a battery for nighttime use, you avoid buying expensive grid power and selling your own clean energy for low credits. This strategy leads to annual savings of around $850 or more, with a system payback period of around 19 years that also includes complete energy security.
