We do solar different…

Solar Is a Great Investment

Installing a renewable, mini-power plant in your home is not a simple task that you want to hire just anyone for. Our focus is a top-quality, reliable system that will perform for decades with minimal hiccups, and ultimately save you far more money than sticking with just grid power or other systems.
Financially Accessible Solar
We have partnered with many community banks and credit unions in the area to be able to provide our clients with a variety of options to make an investment into solar work for them.
‘We’ll Be Right Over’ Service Team
While it’s a rare occurrence, solar and battery backup is complex and sometimes you need an expert to help you understand what’s happening. We have an incredible service team who is available around the clock.
Happy Employees Stick Around & Do Great Work
We have many of the best & most qualified system designers and installers around. Because they’re family, they’re friends, they’re neighbors.
Community First
We grew up here, we have kids here. The Central Coast is our home and we give back however we can. We hire locally, we purchase locally and we put our dollars back into the local economy.
