I had solar panels installed in a duplex by Infinium Solar. We met the deadline of April 2023 to have an NEM2 rate schedule. Even though there were two units, PGE only granted one of them the NEM2 rate schedule. The Solar Department at PGE is very disorganized, and it took us eight very frustrating months to get the issue resolved. Finally, with the help of Kirby Dimaculangan from Infinium, the second unit received the NEM2 rate schedule.. Kirby was really good at getting things moving, his help was invaluable. Without his help, I would still be wrestling with PGE.

We installed our Solar with Infinium but within couple of years the inverter that they installed failed. They have replaced the inverter with new one but problem still exist. Update after writing my review yesterday we finally got our concerns, taking care of and our inverter is back to normal. Thank you Jeff for making it happen.

Infinium Solar did an exceptional job for me! The installing crew, Reuben (Service Tech), Nil Caguimbal (Project Administrator), Nader Barbari (Senior Sales Consultant), Dai Danh (Senior Project Manager) and Jiel Justo (Service Tech) all did an incredible job at designing, permitting, and getting running this project. As a client further away from their HQ, I'm in Sacramento, I'm glad they made the trip out here. Infinium Solar came highly recommended from my mothers neighbor who is an architect. They installed my mothers system and then mine and both times it went great. They really do work with you and PG&E(or SMUD in my case) to get you the system you need or want permitting. Their communication was great, the price was competitive, and their servicing was great. I think they made the trip to my house at least four times to site, build, setup, and service my system at no extra cost. No nickel and diming and just a flat cost for the system. Much appreciated and great job! Can't recommend them enough!

Infinium did good work on my two SP installations. They had to do one warranty claim in a failed micro inverter 4 years after the original install and it was handled quickly and at no cost. If whole house batteries ever come down in price I will likely use them to install three batteries.

I called them to take care of my solar system that was installed 10 years ago and having issues with half number of panels not generating. I called Infinum. They are very responsive. Their sales person (Jacob) contacted promptly at the appointed time and sent the Theo (technician) who diagnosed the problem with wiring. They came back with new estimate after a day and upon approval sent Theo to work on it on the same day and completed the job. Amy Posas was the project co-ordinator and it was so easy to work with her. All of them were very responsive and that made the experience pleasant. I highly recommend Infinium should you have any future needs.
