Recent work around San Antonio

Converse — 21-panel solar detach and reset for a new roof
The roofer needed the array off. We took down 21 modules, protected the wiring, and reinstalled and tested the system once the new roof was on. Done September 2026. See the project →

Northwest San Antonio — 26 kW standby generator
The homeowner was choosing between a 24 kW and a 26 kW Generac. We walked the house, read the loads, and put the two side by side: on natural gas a 24 kW unit delivers about 21 kW, and less on a 100°F afternoon. The 26 kW won. Installing this fall.

Schertz — solar shutdown device and water in a junction box
The system kept faulting. We found a failed rapid-shutdown device and moisture getting into a rooftop junction box, replaced the device and resealed the box entry.

Alamo Ranch, Helotes, Stone Oak — solar installs, 2021–2023
Dozens of Aether-installed systems on San Antonio’s west and north sides, each with its City permit, CPS Energy interconnection and commissioning records in our job files. We still service them.

San Antonio specifics we handle for you

• CPS Energy needs to know about a standby generator or a battery that can back-feed the house. We send the paperwork; you don’t chase it.
• City of San Antonio permits go through Development Services. Backup systems get a load calculation for the address and the generator placards the plan reviewers ask for.
• Outside city limits (Helotes, Timberwood Park and other unincorporated areas) the permit rules change. We check which office has jurisdiction before we quote.

Questions San Antonio homeowners ask

Do you charge to come out? A diagnostic visit has a set fee, and we tell you what it is before we book. When a repair is needed, you get the price before we start.

Generator or battery? A generator runs as long as there’s gas; a battery is silent and switches over with no blink. Plenty of San Antonio homes end up with both. Whole-home backup

My solar company went out of business. Will you work on it? Yes. That’s a big part of our solar work. Orphaned solar service
