Benchmark Cost Analysis

What Does Energy Independence Cost in Brushy Creek?

A full resilience package featuring solar panels and a home battery costs approximately $23,500 before incentives. After applying the 30% federal tax credit, the net cost drops to around $16,450. This investment solves the grid instability problem and provides decades of energy savings. While a solar-only system is a cheaper entry point at about $8,050 after credits, it will not provide backup power during an outage, which is the primary concern for most local homeowners today.

Incentives & Tax Credits

Federal and State Incentives for 2026

The path to energy independence is paved with powerful financial incentives:

  • 30% Federal Tax Credit: This is a dollar-for-dollar credit that reduces your federal tax liability by 30% of the total system cost, including the battery.
  • No Property Tax Increase: Texas state law exempts the added value of your solar system from your property taxes. Your home is worth more, but your tax bill doesn't go up.
  • Sales Tax Exemption: All solar and storage equipment is exempt from sales tax in Texas, saving you over $1,900 on a typical solar and battery installation.

How Solar & Storage Work with the Texas Grid

In Texas's deregulated market, your home remains connected to the grid through your transmission utility (like Oncor), but you buy power from a Retail Electric Provider (REP) of your choice. With a solar system, you produce your own clean energy during the day. Any excess power you don't use can be sent to the grid for a credit, provided you're on a solar buyback plan from your REP. A battery changes the game by allowing you to store that excess energy yourself. Instead of selling it for a potentially low rate, you can use it to power your home at night or, more importantly, during a complete grid blackout.

Projected Savings

Monthly Savings and Energy Security

A properly sized system provides two layers of value. First, it significantly reduces or even eliminates your monthly electricity bill, which averages around $140 in the Brushy Creek area. A typical system can save you over $800 annually on energy costs alone. Second, and for many the most valuable part, is the energy security. When the grid goes down, your home's power stays on, running essential appliances like refrigerators, AC units, and medical devices without interruption. This resilience is something you can't put a price tag on during a summer heatwave or winter storm.

Local Questions Answered

What happens to my power during an ERCOT outage if I have solar and a battery?
Your system will automatically and seamlessly disconnect from the grid and your battery will begin powering your home. Your solar panels will continue to function, recharging the battery each day. You may not even realize the grid is down.
Will a solar-only system work when the power is out?
No. For the safety of utility workers, standard grid-tied solar systems are required to shut down during a blackout. Only a system paired with a battery can provide backup power.
Can I get paid for sharing my battery power in the Austin area?
Yes, this is becoming more common. Some REPs are offering Virtual Power Plant (VPP) programs that pay homeowners for allowing the utility to draw small amounts of power from their battery during peak demand, creating an additional way to earn money with your system.
