Reviews

Straight from our customers

Off-grid install
“This crew were amazing. I had competitive bids on our solar installation (off grid BTW) so I had a comparative sense of capabilities in this area. First they were very price competitive (actually best price). The quoting documentation was exceptional … the installation works beautifully and looks so elegant. Can't thank Jacob and Jack enough. You can't go wrong with these guys”

Outstanding Solar Installation Experience

“I couldn't be happier with my solar and battery backup installation from TRU Off Grid! Jack, the owner, made the entire process seamless from start to finish. … The project was completed in June 2025, right on schedule and on budget.”

“My experience dealing with Tru Off Grid has been nothing short of exceptional. My 12 KW system was installed in one day and included the electrical setup, etc. It was installed on the exact date agreed upon, and both Jack and his electrician were helpful, professional and courteous.”

Battery backup
“Very informative, awesome customer service. I've called numerous contractors who were in a rush, unable to explain, etc. I am truly happy I spoke to Jacob who was able to explain my solar+backup options. Definitely recommend.”

Shop customer
“Fabulous personalized customer service! They didn't just sell me a product. They gave me design suggestions for my project and helped me pick the right product to work best for it. This is the kind of "go the extra mile" customer service that is disappearing in an Amazon world.”
