Estimated 2026 Solar Installation Costs
For a home in the Harker Heights area, a system sized to offset the average electric bill of around $159/month requires careful planning. Here are the baseline modeled costs:
- Standard Solar System (8.7 kW): The estimated upfront cost is approximately $21,750. This price reflects a complete installation designed for long-term production.
- Solar + Battery System (8.7 kW panels, 10 kWh battery): For homeowners wanting to maximize their solar energy use and have backup power, adding a battery brings the estimated cost to $36,750.
These costs are the starting point for calculating your return on investment. The real value emerges when you compare this one-time cost to decades of reduced or eliminated electricity bills.
Incentives & Tax Credits
Key Texas Incentive: The Property Tax Exemption
Even without a federal income tax credit, Harker Heights homeowners have a major financial tool at their disposal: Texas's property tax exemption for solar installations.
When you install a solar panel system, the value of your home increases. However, state law allows you to file Form 50-123 with the Bell County Appraisal District to exempt 100% of that added value from your property taxes. This is a crucial benefit that prevents your tax bill from rising while you enjoy lower electricity bills. Additionally, an owned solar system can be a strong selling point, potentially improving your home's resale appeal to future buyers.

Navigating Solar Buyback Plans in Central Texas
Harker Heights is in a deregulated energy market, which means there is no single, standard 'net metering' program. The value of your exported solar energy is determined by the specific buyback plan offered by your Retail Electricity Provider (REP).
Most REPs credit surplus solar at a wholesale or 'avoided cost' rate, which is much lower than the retail rate you pay for electricity. This economic reality makes systems that are sized for self-consumption—and especially those paired with a battery—the most effective way to achieve energy independence and financial savings.
Projected Savings
Projected Savings on Your Harker Heights Electricity Bill
Your savings come from producing your own power instead of buying it from the grid at roughly $0.16/kWh. Since Texas's grid rules mean you get very little credit for power you send back (modeled here at just $0.04/kWh), using your own solar power is four times more valuable than exporting it.
- The solar-only system is modeled to generate about $1,074 in electricity savings per year, leading to a payback period of around 17.6 years.
- Adding a battery storage system boosts annual savings to $1,664. By storing excess solar power from the afternoon and using it in the evening, you avoid selling low and buying high. This can shorten the payback timeline to about 16.9 years.
Long-term utility inflation can significantly improve these numbers. As grid power gets more expensive in the coming years, the value of each kilowatt-hour your panels produce increases, enhancing your return on investment.
