 Trustindex verifies that the original source of the review is Google. Simmitri installed our Enphase solar panels and later our battery system. They did a terrific job.   Our system runs well after three years. They were good to work with. Their office helped us with the California document submission. We are pleased!

 Trustindex verifies that the original source of the review is Google. After interviewing 3 solar companies I selected Simmiti for my dolar installation. The planning and submissions to PGE and SCCounty Building were done in a timely manner. The installation crew was superb. The inspector was highly impressed with the installation. Ana, my PM, stayed on all parties to get the final steps of approvals. I highly recommend Simmitri for your solar project. 9/12/2025 I just recently added 6 panels to my system (added e-car) and Pamela at Simmitri handled my project. Communication throughout the project was excellent and the crew, once again were FANTASTIC! Simmitri is a pleasure to work with.

 Trustindex verifies that the original source of the review is Google. We can say that installing and working with Simmitri was a seamless experience. They did exactly as they say they would. The staff is amazing to work with, especially the Project Manager Pamela Rodriguez and the Sales Manager Lonnie Cory. The installation crew was fast, clean and friendly. All in all, a great experience working with them from the beginning... and continuing. We are so happy with our new system!

 Trustindex verifies that the original source of the review is Google. Our project began in 2020 with the construction of our new home. When we were ready for our Solar installation, Jonathan walked us through every step of the way. The installation crew were fast, competent, and thorough. We couldn't have asked for a better experience!!

We had a complicated project with a complicated team and every question was answered in a timely fashion. Every one of the reviews I read is spot on. Thank you, Simmitri.
