— Whole-home battery backup
Say no to blackouts. Keep the power on.
Texans know the grid isn't bulletproof. Standard grid-tied solar shuts off during an outage — a whole-home battery backup keeps your lights, refrigerator, internet and AC running while the neighborhood sits dark, and recharges from the sun every day.
02 — Store your sunshine
Use your solar at night
Store excess daytime production and burn it in the evening instead of buying peak-rate power from the utility.
03 — Future-ready
Built for EVs & growth
Home battery backup works with or without panels today — and scales as you add an EV, a pool, or more solar later.

Is solar worth it in Texas?
For most Texas homeowners, yes — when the system is sized honestly. Abundant sun, rising utility rates and frequent grid strain make solar plus battery backup one of the strongest home investments in San Antonio. The key is a design built around your actual usage, not a commission.
How much do solar panels cost in San Antonio?
It depends on your home’s usage, roof and whether you add battery backup — which is why we start with a free on-site solar analysis. We design to your budget, offer the industry’s best financing options, and never pad the price with big sales commissions.
Do I need battery backup with my solar panels?
We strongly recommend it. Standard grid-tied solar shuts off during a blackout for safety — a whole-home battery keeps your lights, refrigerator, internet and AC running when the grid goes down, and stores your excess solar for the evening.
Can I get home battery backup without solar?
Yes. A home battery backup system can charge from the grid and power your essentials through an outage — and you can add solar panels later. We size the battery around what you actually want to keep running.
What happens to my solar during a CPS Energy outage?
Without a battery, grid-tied panels shut down automatically to protect line workers. With whole-home battery backup, your system islands itself and keeps producing and powering your home through the outage.
What financing options do you offer?
We carry the industry’s best financing options for residential installs and multiple financing and leasing structures for commercial projects. We’ll walk you through real numbers at your free consultation — no pressure.
Do you handle permits, CPS Energy interconnection and incentives?
Yes — we handle the paperwork, permitting and utility interconnection end to end. Incentive programs change often, so we review exactly what’s active for your address as part of the free analysis.
What roof types can you install on?
Residential: all roof types, plus ground mounts and carports. Commercial: ballasted, flat, TPO and metal roofing, ground mounts and parking structures.
Do you install solar in Austin?
Yes — we serve the Greater San Antonio and Greater Austin areas with the same local Texas crews. We only serve Texas, and we like it that way.
Who installs and services my system?
The same local, salaried Alamo team that handles our security installs — not an out-of-state subcontractor. If you ever need service, you call us and a local tech shows up.
