What Does Solar & Battery Cost in DeSoto in 2026?
To achieve true energy independence, a combined solar and battery system is the recommended path. The gross cost is around $23,500, but after claiming the 30% federal tax credit, your final investment is approximately $16,450. This system provides substantial savings and invaluable peace of mind during grid outages.
For homeowners focused purely on the lowest upfront cost, a solar-only system is an option. It costs about $11,500 before incentives, or $8,050 after the federal tax credit. While cheaper, it leaves you more exposed to changes in REP buyback rates and offers no outage protection.
Incentives & Tax Credits
Key Financial Incentives for DeSoto Homeowners
The upfront cost of solar is made much more affordable by several key incentives:
- 30% Federal Tax Credit: Reduce your federal tax liability by 30% of your total system cost. For a typical battery system, this is a credit worth $7,050.
- 100% Property Tax Exemption: Texas law ensures that the significant value solar adds to your home won't appear on your property tax bill.
- Sales Tax Exemption: You won't pay the 8.25% local and state sales tax on your solar equipment, a direct saving of over $1,900 on a battery system.

Oncor, REPs, and Your Solar Credits
In DeSoto, Oncor is the utility that owns the power lines and delivers your electricity, but you buy that power from a Retail Electric Provider (REP). When you go solar, that REP is also responsible for crediting you for any excess power you send to the grid. Unfortunately, these 'solar buyback' plans aren't standardized. Some are great, others are poor, and all of them can change. This uncertainty makes a strong case for pairing solar with a battery, allowing you to store your extra solar power for your own use and minimize your dependence on REP policies.
Projected Savings
Your Potential Annual Savings in DeSoto
A modest 4 kW solar installation on a DeSoto home will generate about 6,105 kWh of electricity per year. With average rates from local REPs hovering around $0.14/kWh, that solar production slashes your bills by approximately $855 each year. That's money that stays in your pocket instead of going to an electricity provider. With a solar battery, you can push those savings even higher by using stored solar energy during peak evening hours when grid power is most expensive.
