Is Solar Still a Good Investment in DeSoto for 2026?
For homeowners in DeSoto, the combination of intense Texas sun and high summer air conditioning bills makes solar a compelling option. But with the end of the 30% federal tax credit and variable buyback rates from retail electricity providers, understanding the current costs and savings is essential. The key to solar value in the Dallas County area now lies in maximizing self-consumption—using the power you generate directly in your home.
An owned solar system can also be a significant long-term asset, potentially improving your home's resale appeal and providing a hedge against future increases in grid electricity prices.

2026 Solar Panel Costs in DeSoto
Based on local market data for early 2026, a typical 8.7 kW solar system in DeSoto costs around $21,750 before any incentives. This price reflects installation, quality hardware, and necessary permits. Since the federal tax credit for systems placed in service in 2026 is no longer available by default, this gross cost is also the net cost.
- Solar-Only System (8.7 kW): $21,750
- Solar with Battery (8.7 kW system with 10 kWh battery): $36,750
Adding a battery increases the upfront cost but can improve the system's financial performance by storing excess solar energy for use at night, instead of selling it back to the grid for a low price. It also provides valuable backup power during grid outages.
Incentives & Tax Credits
Texas Solar Incentives for DeSoto Homeowners
While the major federal tax credit has ended, Texas offers a powerful state-level incentive that makes going solar more affordable. DeSoto residents can benefit from:
- 100% Property Tax Exemption: This is the most significant financial perk in Texas. Installing a solar system will not increase your property taxes. You can claim this exemption by filing Form 50-123 with the Dallas Central Appraisal District. This ensures you get the home value boost without the tax burden.
- Retail Electric Provider (REP) Buyback Plans: In Texas's deregulated market, some REPs offer plans that credit you for the excess solar energy you send to the grid. The value of these credits varies widely, so it's important to shop for a plan that works well with solar.

Understanding Solar Export Rules in DeSoto
Texas does not have a statewide net metering mandate. This means your local utility or REP is not required to buy your excess solar power at the full retail rate. In the ERCOT grid that serves DeSoto, the value of your exported solar energy is determined by your chosen Retail Electric Provider.
Most solar buyback plans offer a credit rate far below what you pay for electricity. For this analysis, we use a conservative export rate of $0.0397 per kWh, while the purchase rate is $0.1587 per kWh. This difference is why using your solar power directly—or storing it in a battery for later—provides the best financial return.
Projected Savings
Potential Energy Bill Savings in DeSoto
With an average electricity rate of $0.16/kWh, a DeSoto household can achieve significant savings by generating its own power. The exact amount depends on whether you add a battery.
- A solar-only system is modeled to save approximately $1,074 per year, leading to a payback period of about 17.6 years.
- Pairing the system with a 10 kWh battery boosts annual savings to $1,664 and shortens the payback period to 16.9 years. The battery helps you avoid selling your valuable solar power for the low export rate of around $0.04/kWh, saving it for when you need it most.
These savings can become even more valuable if grid electricity rates continue to rise over the 25+ year lifespan of the solar panels.
