Rethinking Your Electric Bill in Ennis
For homeowners in Ennis, the high summer heat means air conditioning runs constantly, driving up electric bills. A rooftop solar system offers a way to generate your own clean power, but the financial picture in 2026 is different than it was a few years ago. With the default federal tax credit gone, the value of solar depends entirely on local utility rates and Texas's unique energy market rules. The key is understanding how to maximize the power you produce right on your own roof.
An owned solar system can also be a significant asset for your property. Beyond the monthly bill reduction, it can enhance resale appeal for future buyers looking for homes with lower, more predictable energy costs.

2026 Solar Panel System Costs in Ennis
The price of a residential solar installation is based on its size, which is measured in kilowatts (kW). In the Ennis area, a typical home might need an 8.4 kW system to significantly offset its electricity usage. Here’s a look at the estimated costs for 2026:
- Solar-Only System (8.4 kW): The estimated gross cost is around $21,000.
- Solar + Battery System (8.4 kW panels with a 10 kWh battery): This option, which provides backup power during outages, has an estimated gross cost of $36,000.
These costs are the full price before any potential local incentives or financing. Since the 30% federal tax credit is no longer available for systems placed in service in 2026, the primary financial benefits come from bill savings and Texas-specific tax rules.
Incentives & Tax Credits
Key Texas Solar Incentive: Property Tax Exemption
While Texas does not offer a state income tax credit for solar, it provides a powerful financial benefit that many other states lack: a 100% property tax exemption on the value added by your solar system.
Here’s what that means for an Ennis homeowner: Installing a $21,000 solar system increases your home's value, but your property taxes will not go up as a result. You can file a simple form (Form 50-123) with the Ellis County Appraisal District to claim the exemption. This ensures you get the home value benefit without the tax burden, improving your long-term return on investment.
Net Metering: ERCOT
Limited Export Credit
Optional
Understanding Export Credits in the ERCOT Market
Texas does not have a statewide net metering mandate. This means your Retail Electric Provider (REP)—the company that sends your monthly bill—determines the rate they will pay you for excess solar energy you export to the grid. These are often called 'solar buyback plans'.
The export rate of $0.0375/kWh used in this estimate is a conservative figure. Some REPs offer plans with more attractive buyback rates, while others offer very little. The most effective strategy is to size a system that meets your home's daytime needs, minimizing exports and maximizing the direct use of the solar power you generate. A battery helps achieve this by storing surplus energy instead of selling it for a low credit.
Projected Savings
How Solar Creates Value on the Texas Grid
In Texas's deregulated electricity market, your savings depend heavily on how you use your solar energy. You save the most money when your home uses the solar power directly as it's generated. This is called self-consumption.
When you buy electricity from the grid, you might pay around $0.15 per kWh. But when your panels produce extra power and send it to the grid, you might only get a credit of about $0.0375 per kWh. This difference makes self-consumption critical.
- A solar-only system is projected to save an Ennis homeowner around $966 annually by directly offsetting that $0.15/kWh grid power.
- Adding a battery increases the potential annual savings to $1,474. The battery stores excess solar power from the afternoon for you to use in the evening, further reducing how much expensive electricity you need to buy from your provider. While the payback period is similar, the battery adds valuable protection against grid outages.
