Navigating Solar in Texas's Deregulated Market
For homeowners in Humble, the combination of hot, humid summers and the complex Texas electricity market can make energy bills a constant concern. With average electricity rates around $0.16/kWh, many are looking to rooftop solar. But in 2026, the financial equation has changed. The value of solar no longer comes from a simple 1-for-1 grid credit; it comes from smart energy management, especially with the low buyback rates common in most retail electricity plans.

Estimated Solar System Costs in Humble (2026)
The cost of a solar installation depends on the system size and whether you include battery storage. Based on local averages, a system designed to offset a typical Humble electricity bill requires about 10.2 kW of solar panels.
- Solar-Only System (10.2 kW): The estimated gross cost is around $25,500. This setup is designed to cover your daytime energy use.
- Solar + Battery System (10.2 kW panels, 10 kWh battery): The estimated gross cost is approximately $40,500. This option provides energy independence and maximizes your savings by storing excess solar power for use at night.
These figures are pre-incentive estimates. The final price can vary based on your specific roof, equipment choices, and installer.
Incentives & Tax Credits
Texas Solar Incentives: Property Taxes and Plan Selection
While the 30% federal tax credit is no longer available for systems installed in 2026, Texas homeowners have a powerful local incentive:
- 100% Property Tax Exemption: In Texas, adding a solar panel system to your home will not increase your property tax bill. You can claim this exemption using Form 50-123 from the Texas Comptroller. This ensures that the value added to your home doesn't result in a higher tax burden for the life of the system.
- Retail Plan Choice: The deregulated market means you can shop for a Retail Electricity Provider (REP) that offers a favorable solar buyback plan. While not a direct incentive, choosing the right plan is crucial for your system's financial performance.
An owned solar system can also be a strong selling point for future homebuyers, potentially enhancing your property's resale appeal.
Net Metering: Address-specific utility or retail electricity plan
Limited Export Credit
Optional
Understanding Solar Buyback in the ERCOT Market
Texas does not have a statewide net metering mandate. Instead, the value of your exported solar energy is determined by your REP. Most plans credit you at a wholesale or 'avoided-cost' rate, which is much lower than the retail rate you pay. The modeled export rate of around $0.04/kWh reflects this reality. This structure makes it financially advantageous to use as much of your own solar power as possible, either by running appliances during the day or by storing it in a battery for evening use.
Projected Savings
How Solar Savings Work with Low Export Rates
Installing solar panels changes the math when exported power is worth less than what you buy from the grid. In Humble, your retail electricity plan might pay you just $0.04/kWh for excess solar energy sent to the grid, while you pay $0.16/kWh to pull power from it. This is why self-consumption is key.
- A 10.2 kW solar-only system is modeled to save an estimated $1,208 annually, with a payback period of about 18.3 years.
- Adding a 10 kWh battery significantly improves the economics. By storing your excess solar power instead of selling it cheap, this system can save an estimated $1,902 annually, shortening the payback period to 16.5 years.
A battery also offers valuable backup power during grid outages, a significant benefit for anyone who remembers recent ERCOT grid alerts. Furthermore, as utility rates rise over time, the value of the electricity you generate and store at home only increases.
