Why Sentinel
What makes us different from every other solar company in Texas.
PUCT Registered
One of very few solar companies in Texas with full PUCT registration — giving us the ability to offer services, programs, and grid participation that standard installers can't.
Hardware Standards
We specify Sol-Ark 15k inverters and HomeGrid Stack'd batteries because they're the best — not because of vendor incentives. Premium hardware or we don't install it.
Engineered for Texas
Every system is engineered for 150 MPH+ wind loads. After Uri and Beryl, resilience isn't a feature — it's the baseline.
TBPP Grant Navigation
The $1.8B Texas Backup Power Package Program is coming. We're positioned to act as your agent through the entire application process — securing grant funding you'd otherwise leave on the table.
Texas Backup Power Package Program
