Solar System Costs in Sherman, TX for 2026
Your final price depends heavily on whether you include a battery for backup power. While a solar-only system is cheaper upfront, adding a battery provides crucial protection against grid outages—a major concern for anyone relying on ERCOT.
- Solar-Only System (4 kW): Expect a gross cost around $11,500. After the federal tax credit, the net cost drops to just $8,050. This is a great starting point for pure savings.
- Solar + Battery System (4 kW + 10 kWh battery): The total cost is approximately $23,500 before incentives. The 30% tax credit reduces this to $16,450, giving you energy independence during blackouts for about $8,400 more than a panels-only setup.
Incentives & Tax Credits
Federal & Texas Solar Incentives
Texans enjoy some of the best solar incentives in the country. Your Sherman home is eligible for multiple programs that significantly reduce the cost of installation.
- Federal Solar Tax Credit: This is the big one. You'll receive a 30% credit on your federal income taxes for the total cost of your solar and battery system. For a $23,500 solar-plus-battery system, that's a direct $7,050 reduction.
- Texas Property Tax Exemption: Installing solar increases your home's value, but thanks to this exemption, your property taxes won't go up a single dollar because of it.
- No State Sales Tax: All solar equipment in Texas is exempt from the state sales tax, saving you hundreds of dollars right off the bat.
Net Metering: Various REPs (choose provider)
No Statewide NEM
Optional
Navigating Net Metering in the Deregulated Texas Market
Texas doesn't have a statewide net metering mandate, which means your benefits for sending extra power to the grid are determined by your REP. Some providers like TXU Energy or Green Mountain Energy offer excellent solar buyback plans that credit you for your excess generation. It's critical to shop for a REP that rewards solar owners. Without a good plan, the value of your exported energy is low, making battery storage an even smarter financial choice to store and use your own power.
