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.”
