We talked to a few solar companies, but Vast was the only one that actually showed us our real data. Now the battery kicks in every night and our bill is exactly what they said it would be.
Chris & Lauren M.
San Antonio, TX (Solar + Battery)
Our power use was all over the place with the EV and pool. Vast modeled it before install, and now everything runs like clockwork. It’s nice not wondering what the bill will be.
Michael L.
Dallas, TX (Solar + Battery + EV)
Most companies guessed our savings. Vast showed us the proof before we signed. Everything from install to follow-up felt professional and straightforward.
Todd V.
Katy, TX (Solar Only)
We’ve had our system for a year and it’s been flawless. I love seeing what our home’s producing in the app. Vast made it easy and the results speak for themselves.
Eric M.
Rancho Cucamonga, CA (Solar + Battery)
We needed a new roof before going solar, and Vast handled both. No headaches, no delays — just clean work and solid communication. It looks like the system came with the house.
Jason P.
Frisco, TX (Solar)
Everyone else tried to upsell me. Vast explained what made sense and why. We went with one battery instead of two and it’s been perfect. My bills are lower than ever.
Daniel R.
Phoenix, AZ (Solar + Battery)
They didn’t sugarcoat anything — just facts and numbers. Our system performs almost exactly like the design showed. You can tell they actually engineer their systems.
