Solar Installation Perfection With Infinium Solar, Inc.

Jeff Long (CEO), with 15-years experience in the industry and his team at Infinium Solar were just awesome - they customized a solar solution with new panels plus minor repairs on an existing panel installation, and connected the existing panels and the new panels to a single monitoring phone App. Infinium Solar completed the site survey, installation, and city permit process efficiently and rapidly. No other installer was experienced enough to offer this level of customization at a very reasonable price. I highly recommend Infinium for any of your Solar Projects.

Excellent work by Infinium Team

Infinium Solar did an outstanding job for a 14 panel Solar system on my house. They were quick and were able to get the entire project done within the timeline they gave to me initially. Most importantly, i like that they are local to San Jose and have in house installers for electric and solar work. Before starting with Infinium Solar, i was working with Project Solar (another company) who were not able to do any work in 8 months which was kind of disappointment for me. Kenny(my solar consultant) from Infinium Solar was very professional and kept me updated through the entire process. I would recommend them to my friends and family for future solar work.

Great Job

Infinium Solar has been an great partner to install the solar system in my house. The prices were extremely competing and so was the work done . Jeff(CEO) and his team is somebody who you can trust. They were proactive is providing granular updates on the schedule and got the job done as promised. The installation was done in 2 hours without any botheration of commitment of my time. The whole process from request to quote to pass of final inspection had zero presence of mine and was only limited to minimal emails and phone calls. I had gone thru half a dozen of vendors to negotiate on price and workmanship to zero in on Infinium Solar , and they lived up to expectation.

Production Overstated

Infinium installed a 13-panel residential system on my house. I chose Infinium for the highest advertised energy production at a reasonable price. Installation was very quick and professional. Infinium also installed a 240V EV charger of my choice in my garage. Electrical conduit was painted to blend in with the house wall. Very professional and polite crew. Inspection and PG&E process handled smoothly and quickly. So, 5 stars for the installation process. However, first year production was 15% lower than advertised, which is a big deal for me, as I was planning to buy another EV. Reached out to Infinium. Response from the owner: one or two panels are getting partially shaded in the afternoon by the chimney and the nearby tree, that is why peak production is lower and is in May, instead of June-July. My take: this doesn't add up, as 15% production loss implies that 2 out of 13 panels are fully shaded 100% of the time (2/13=0.15), and this is plainly not the case for my roof. So, 1 star for overstating production and not addressing my valid concern. In summary, buyer beware: I did not get an honest deal from Infinium.

Awesome Company!

I talked to about 6 companies when we started looking for a solar and battery system. Jeff at Infinium Solar. He listened to what we were trying to do and explained all the options available. We had a very unique electrical panel and Infinium was able to upgrade the main electrical panel and get us to a full home backup with a 10KW solar system. The process was very fast and they kept me updated as the project progressed. I recommend Infinium to many friends and family and all have had a great experience.

I am happy to report I did pick the right company to install the solar on my home in Willow Glen! First I would like to thank Jeff Long, Owner, who guided us along the entire process and answered all of our questions along the way. His in-house team who helped us with monitoring was great - This is a super hands on company who makes your solar installation easy! I highly recommend Infinium Solar and their entire team! Thank you!!
