We used Sustineo on a 1.3MW Installation across four automotive dealerships in San Diego, both rooftop and canopy installations. They were extremely professional and very easy to work with. We have recommended them to many other businesses looking to do a commercial solar installation and will continue to do so. Working with Sustineo has been a great business partnership; we still use them for all maintenance and support of our systems.

It is my pleasure to write this review. Sustineo has been a great partner for our solar proof and battery storage system for L. A. Press, a trade commercial printing plant on the south side of Los Angeles. We started early in 2019, design and engineering, city approval, ordered Tesla battery, SGIP application submitted and were waiting for approval. Then the pandemic hit, everything came to a halt, and the SGIP program was in limp mode. Slowly, we got back in again, finally the SGIP program was approved for our project. Then it started rolling, everything was preplanned and prescheduled. We have a Teams meeting very week, tracking progress and updating each department; very professional and very organized. Jim Coleman was our main guy, and he was available to answer every phone call and email. Finally, our project got done and operational around Oct. 2021. I'm so excited; can't wait to see how much money I'm gonna save next year. And just want to thank the whole Sustineo team for doing such a great job.

Sustineo Corp has shown a deep knowledge and mastery of the NEC and applicable electrical and PV standards, continuously providing their support on the scrupulous compliance of the design during the engineering and construction stages. (They have) proved to be a reliable partner in the management of permitting and dealing with local authorities for the approval of designs and calculations. Isolux would recommend Sustineo Corp to prospective clients and would work with (them) in future projects.

It’s been well over six months since our Redlands Headquarters solar PV installation came on line. Since the system was commissioned, it has been producing nearly 25% of our site’s electricity and has been problem-free. Thank you for helping to make this first landmark solar project an enormous success!

I would like to take this opportunity to express my appreciation to (Southern California Edison) about the Sustineo design team for a job well done on the subject contract. Your overall rating is “Outstanding” as reflected on the Navy’s performance evaluation. The Navy needs good responsive contractors, and Sustineo is an outstanding example for other contractors to emulate. Thank you for performing in such a professional manner. It was a pleasure doing business with your company.
