Wow I've been in the market for solar lately and I came across them through a friend who recently got their solar installed by them. I called them for an inquiry and Alex and such a sweetheart. He broke everything down for me and told me what I should expecting. Their crew was so professional and they're willing to work with you. Their service was superb and knowledgeable. I will definitely refer this to my friends and family.

Despite initial hesitation due to reviews, I chose True Renewable Energy based on a neighbor's recommendation and was glad I did. Mike was thorough, explained the entire process, and offered a competitive price I couldn't refuse. He was always available to answer my questions, and I’m thrilled with the results. Thanks, TRE, and thank you, Mike, for showing me how my meter goes backwards!

I discovered TRE through Instagram and was initially skeptical, but they exceeded my expectations. Angel (Sayed) was exceptional—knowledgeable and professional, answering all my questions about their high-quality products and great warranties. He even guided me on qualifying for government programs like PACE with no upfront costs. Highly recommend TRE for windows, solar, HVAC, and more!
