"I've worked with my fair share of contractors and Matt the owner of TENCO SOLAR impressed me right off the bat. He is not only personable but very accommodating and clearly and expert on solar. He worked with me on a 1000 unit apartment complex and I have plans to work with them again on our new buildings."

From the initial consultation to the final touches, they've consistently demonstrated a high level of professionalism, deep domain expertise, and complete transparency in all their dealings. Even after the installation, their support has been outstanding, with prompt follow-ups and thorough answers to all our questions.
