Take Control of Your Energy Costs

Joe has owned his home in Vacaville for 13 years. He talks about what the process is like going solar. 


We provide Zero Down Solar Solutions for homeowners just like you throughout California. We offer many different options including PPA’s, ownership, ground mounts and high efficiency panels. We’ve put in place all the protections and guarantees to give you complete peace of mind that solar will save you money and make your life better.


We are partners and licensed installers of Generac Home Generators, the #1 selling home standby generator brand. We connect it to your existing LP or natural gas fuel supply, and kicks in within seconds of sensing power loss and runs for as long as necessary until utility power returns. Even if the utility company shuts off power, all the electrical outlets in your home will still work!


Are you in the market for a new roof or need a repair? We bet there’s a lot of questions going through your mind right now. Will my Homeowners Insurance cover the cost? Should I finance? What kind of roof do I have? What kind do I want? What kind should I want? Our C-39 licensed roofers will answer all your questions. Absolutely no-pressure.


Generac PWRcell is an intelligent energy storage system. Equipped with PWRview energy monitoring technology, PWRcell protects you during times of power outage and allows you to control your energy usage to save on utility costs.

My install was very clean and very professional. I had many questions and they helped answer them all. They kept me informed on how long PTO (Permission to Operate) would take with PG&E; and I’m excited!

The company came out rather quickly to set-up the ground mount system. There were a few problems when the ground mount was trenched. The crew took care of the issues the same day and everything worked great. I was impressed with the team. They showed-up on-time and stayed until the work was complete. They had lots of enthusiasm and dedication to detail. I would highly recommend this crew, and company, for your solar needs!
