Highly Reviewed | Local | Family-Based

Our History

Located and installing systems in the Bay Area, we have been serving our neighbors with high-quality, custom-designed rooftop solar and home battery backup systems for over two decades. We are a family-based company that serves a variety of clients around California from all walks of life. We match systems to our customers needs and desires, from the large systems that eradicate energy bills to smaller ones that provide security and reduce dependance on the grid.

Highly Reviewed & Local

All the marketing in the world pales in comparison to honest reviews from real customers. At OSullivan Green Solar, we enjoy 100% five-star reviews from our customers as well as being an A+ rated business accredited with the Better Business Bureau. When choosing your installation company, we encourage to take at look at our reviews on Yelp to see why so many fellow neighbors choose us to provide, design, and install their system.

Our Values

At OSullivan Green Solar, we value communication, education, and family above all else. These values guide how we work as a company and how we work with our customers. We don't pressure with pushy sales tactics or tricky marketing language and fine print. It is our goal to educate our customers and make sure everyone is on the same page regarding system size, panel quality, and everything else that goes into installing your system.
