Benchmark Cost Analysis

2026 Solar Panel Installation Costs in Flower Mound

The upfront investment for a solar energy system is a key factor for homeowners. In early 2026, the average cost for a quality installation in the Flower Mound area is approximately $2.50 per watt.

  • The gross cost for a typical 8.7 kW solar-only system is estimated to be $21,750.
  • For homeowners wanting backup power and maximized savings, a solar and battery system has an estimated cost of $36,750.

While this is a significant home improvement project, an owned solar system is a long-term asset. Unlike a leased system, it can add to your home's value and may improve its resale appeal to future buyers.

Incentives & Tax Credits

Primary Solar Incentive: Texas Property Tax Exemption

As of 2026, the primary financial incentive for homeowners going solar in Texas is the state's generous property tax exemption. The 30% federal tax credit that was previously available is no longer applicable for new residential systems.

Here’s how the Texas incentive works: Installing a solar system adds significant value to your home. However, state law allows you to exempt 100% of that added value from your property tax assessment. By filing Form 50-123 with the Denton County Appraisal District, you ensure your tax bill doesn't go up because of your solar investment. This is a crucial, long-term financial benefit that makes solar more affordable.

Understanding Solar Buyback Plans in Texas

Flower Mound is in a deregulated energy market, meaning there is no state-mandated 'net metering' policy that forces utilities to buy your excess solar power at the full retail rate. Instead, your financial benefits depend on the specific 'solar buyback' plan offered by your Retail Electricity Provider (REP).

These plans typically credit surplus energy at a much lower wholesale rate. Our calculations use an estimated export value of $0.0397 per kWh, which is significantly less than the average retail purchase price of $0.1587 per kWh. This makes self-consumption—using solar power as it's generated—the most effective way to save money. A battery helps achieve this by storing daytime energy that would otherwise be sold for a low price.

Projected Savings

How Much Can You Save with Solar in Flower Mound?

A professionally installed solar panel system can significantly reduce your monthly electricity costs. Based on local sun exposure and a typical 8.7 kW system size, the estimated first-year savings are substantial.

  • A solar-only system is modeled to save a Flower Mound homeowner approximately $1,074 in the first year. The estimated payback period is around 17.6 years.
  • By adding a 10 kWh battery, you can store your excess solar power for evening use. This solar-plus-battery system boosts first-year savings to about $1,664 and can shorten the payback time to 16.9 years.

Solar is not just about today's bill. As utility rates trend upward over time, generating your own power provides a valuable hedge against future price increases, making your savings more powerful in the long run.

Local Questions Answered

What happens if I produce more energy than I use in Flower Mound?
Any surplus electricity you don't use or store in a battery is exported to the grid. Your Retail Electricity Provider (REP) will credit you for this energy, but usually at a low wholesale rate, not the full retail price you pay. That's why using your solar power directly is more valuable than selling it.
Does adding a battery make financial sense in Texas?
A battery can improve the financial return of solar in Texas. It allows you to store cheap, self-generated solar power from the afternoon and use it during the evening, instead of buying expensive power from the grid. It also provides critical backup during power outages, which adds a layer of energy security.
How do I claim the Texas property tax exemption for solar?
To claim the exemption, you need to submit the Application for Exemption of Solar or Wind-Powered Energy Devices (Form 50-123) to your local county appraisal district, which for Flower Mound is primarily the Denton CAD. This form prevents the assessed value of your home from increasing due to the solar installation.
