Appreciated the help

While we did not ultimately chose to use Infinium, they kept in regular contact, offered a very competitive bid, and offered valuable insight regarding the elements we should have been aware of in our efforts to add a solar and battery solution to our home. I would gladly recommend them to anyone else interested in doing the same.

Home Battery Installation by Infinium

Infinium did a great job of analyzing the uniqueness of how my panels and sub-panels are set up to determine the best, and most cost-effective setup for our home battery addition. Their staff are great and responsive.

Outstanding Solar Company

Infinium Solar did an outstanding job on my solar project! From start to finish, the team—including Reuben (Service Tech), Nil Caguimbal (Project Administrator), Nader Barbari (Senior Sales Consultant), Dai Danh (Senior Project Manager), and Jiel Justo (Service Tech)—handled the design, permitting, and installation with incredible professionalism. Even though I’m based in Sacramento, further from their headquarters, they made multiple trips (at no extra cost) to handle site visits, installation, setup, and service. I truly appreciated the flat pricing with no hidden fees or nickel-and-diming. Infinium came highly recommended by my mother’s neighbor, an architect, who first referred them for my mother’s system. That installation went perfectly, so I trusted them for my own—and they exceeded expectations again. Their communication was clear, their price was competitive, and they worked seamlessly with SMUD (and PG&E for others) to ensure everything was permitted and running smoothly. I couldn’t be happier with the results. Infinium Solar is reliable, transparent, and customer-focused. I highly recommend them!

Easy company to do business with!

Infinium is a well-organized and professional company. The entire process—from consultation to installation—was smooth and straightforward. Jeff, the owner, personally met with me at my home to evaluate the best positioning for the solar panels. He then sent over a detailed proposal for me to review. At no point was there any pressure to move forward, which I really appreciated. I felt very comfortable choosing Infinium. The company is highly service-oriented and responsive to any concerns or questions. Every time I called, someone picked up, and the front desk staff was excellent at connecting me with the right person. Dai and Jerome were great to work with throughout the process. The installation itself went smoothly. The installers were friendly, professional, and respectful of my property—especially when working on the roof. They also took the time to answer all my questions about the installation process. After the install, their system technician, Jiel, helped me connect my system to the internet and answered any questions I had about monitoring energy production. She made sure I was comfortable with the system before wrapping up. Overall, my experience with Infinium Solar was outstanding. I highly recommend them to anyone considering a solar energy system.
