Massive growth and high summer temperatures in Frisco mean homeowners are seeing bigger and bigger electricity bills. With the Texas grid's stability still a major concern, installing rooftop solar is about more than just savings—it's about energy security. For a typical home here, a solar panel system can eliminate a huge portion of your monthly bill and pay for itself over time, all while protecting you from ERCOT's price spikes.

Benchmark Cost Analysis

Breaking Down Solar Costs in Frisco for 2026

So what's the real price tag? A standard solar-only system designed for a Frisco home typically costs around $11,500 before incentives. After applying the 30% Federal Tax Credit, that drops to just $8,050.

However, for true energy independence from the ERCOT grid, most homeowners are now opting for a solar and battery combination. This increases the upfront cost to around $23,500 (or $16,450 after the tax credit), but it ensures your lights stay on during a blackout. While the payback period is longer at nearly 20 years, the peace of mind is priceless during Texas summers.

Incentives & Tax Credits

Available Solar Incentives for Frisco Homeowners

Texas offers excellent incentives that make going solar much more affordable:

  • Federal Solar Tax Credit: The biggest saving grace is the 30% federal ITC. For a $23,500 solar-plus-battery system, this credit returns $7,050 to you at tax time.
  • Property Tax Exemption: Your home's value will increase with solar, but thanks to a state exemption, your property taxes won't. The added value is 100% exempt.
  • No State Sales Tax: Solar equipment is exempt from state sales tax in Texas, saving you hundreds of dollars on the initial purchase.

Navigating Solar Buyback Plans in a Deregulated Market

Texas doesn't have a statewide net metering law, which can be confusing. Your ability to sell excess power back to the grid depends entirely on your Retail Electric Provider (REP). Many REPs in the Oncor service area (which covers Frisco) offer solar buyback plans, but the rates vary wildly. Some offer near-retail rates, while others pay only a few cents per kWh. This variability is why pairing solar with a battery is so strategic—you can store your excess energy for your own use instead of selling it for pennies on the dollar.

Projected Savings

Your Expected Solar Savings in Collin County

With an average electricity rate around 13.3¢/kWh, a properly sized solar system in Frisco can generate roughly $823 in electricity savings each year. Over the 25-year warrantied life of the panels, that's over $20,500 in avoided utility payments. Even better, you lock in your energy costs, protecting your family from the volatile rate hikes common in the deregulated Texas market.

Local Questions Answered

How do I choose the right REP for solar in Frisco?
Research REPs that offer favorable 'solar buyback' or 'renewable energy' plans. Websites like Texas Power Guide can help you compare options. The key is to find one that credits you a fair price for the extra power your panels produce.
Does a battery make financial sense with the longer payback?
Financially, a solar-only system has a quicker payback of about 10 years. But the battery's value is in resiliency. Given ERCOT's history of outages, many Frisco families see the approximate $16,450 net cost of a combined system as an investment in keeping their AC, refrigerator, and lights running during a grid failure.
How many solar panels do I need for my home in Frisco?
A typical starting point is a 4-5 kW system, but the exact size depends on your electricity consumption, especially during the summer. Our calculator below can give you a more precise estimate based on your actual usage.
