Backup Power
During an outage, a properly installed battery can power selected circuits or a larger portion of your home, depending on capacity and design, helping keep lights, refrigeration, and communications running.

Home Battery Backup and Tesla Powerwall Installation
Store more of the solar energy you produce and keep important loads running when the grid goes down. SolCheck installs home battery storage for homes in Cibolo, New Braunfels, Seguin, and the Guadalupe Valley.
Why Add a Home Battery?
Texas weather and periods of high demand can interrupt utility power. Pairing solar panels with a battery gives you more control over when you use the energy your system produces.
Use More of Your Solar
When your panels produce more than your home is using, a battery can store the extra for evenings and cloudy days instead of sending it all back to the grid.
Sized to Your Priorities
We help you identify which loads matter most, then size storage around your typical usage and backup goals.

Tesla Powerwall
Tesla Powerwall for Cibolo and Guadalupe Valley Homes
For homeowners across Cibolo, New Braunfels, Seguin, and nearby communities, a home battery can store electricity from a solar system and help keep important loads running if the grid goes out. SolCheck installs Tesla Powerwall systems and can help you decide whether a Powerwall is a good fit for your home, your existing or planned solar array, and your backup needs.
How the Tesla Powerwall Works
Solar panels typically produce the most electricity in the middle of the day. A home battery can store some of that electricity so you can use it later, including in the evening, on cloudy days, or during a grid outage, depending on how the system is designed and configured.
Compatibility depends on your equipment and electrical setup. If you already have solar, we’ll review your system before recommending a Powerwall. If you’re starting from scratch, we can design solar and storage together.

Storage Capacity and Incentives
Tesla publishes usable capacity and power ratings for each Powerwall model, and those figures can change. During your consultation, we’ll size storage around your usage and backup priorities and confirm whether one unit or more is appropriate.
As of November 14, 2026, the IRS states that the federal Residential Clean Energy Credit is not available for property placed in service after December 31, 2025, which included qualifying battery storage when the credit was in effect. We do not include that credit in 2026 estimates. Other programs may apply depending on current law and your eligibility. We don’t provide tax advice; confirm credits with a qualified tax professional.
