Most knowledgeable and best customer service in the industry. It's been 5 years since my install and Joe quickly follows up to my service requests or questions with quick resolutions. Joe and his staff are very professional and reputable. I highly recommend Solargem.

I had them install my system several years on a house that I ended up selling. Because of their professionalism and courtesiness the first time I went with them to install new system on the house that I bought to continue saving money on my electric bill, and once again they did an outstanding job helping to make sure I had a large enough system for the new house. And once again they were very courteous and very professional. Every time I talk to someone who is thinking about going solar I always tell them to utilize this company if they decide to because they will not be disappointed with their work and planning the system out.

It is now one year after installation. There have been no problems whatsoever with the system. Joe designed it to give a net electric bill of zero. We are going to owe Edison about $50 for the YEAR! That's awfully close to zero. I looked at daily usage. The system generates enough energy even on the shortest day of the year on sunny days to cover the entire 24 hour period. Of course it also depends on the weather, the more cloudy days, the less your system generates. If you're in the market for solar, read the other reviews and then give Joe a call. You have nothing to lose and lots to gain.

Finely I can write a review for our Solar system. We have since September 2011 a Solar system on our roof. We get paid every month our electric bill and we safe each month some trees. Our big concern was to find a good company to put the Solar on the roof. We found one of the best family company we ever hired for our house. They were very knowleable and did what they sad. Joe Johnson did a excellent job for us.

Joe Johnson and his crew upgraded my system with panel panels and additional batteries. They also replaced my main box. What fantastic people! Timely in their work habits and neat and clean in their work, you can’t go wrong hiring Solargem. They are great communicators and true to their word.
