The Mission of Sun Light & Power is to create a living environment that serves people's intrinsic needs, supports the human spirit and preserves the planet's resources for future generations.

Since then he has helped assemble one of the solar industry’s most talented teams. They bring to each project unparalleled expertise, innovative solutions, energy-efficient solar technologies and outstanding customer service.

Sun Light & Power is committed to making a positive difference in the world, both by providing exceptional service, products and expertise in solar energy to our customers, and by standing as an example of the great business practices that support our team members and the community that we live in.

Proud to be a Certified Benefit Corporation

Sun Light & Power is both a California Benefit Corporation (an alternative form of legal incorporation that enables for-profit entities to integrate social and environmental goals into their business operations) and a certified B Corp (a trade designation developed by the nonprofit B Lab). Both of these designations signal our fundamental belief that the power of business can be used to tackle important social and environmental problems, while providing a healthy and sustainable workplace for our employees. Sun Light & Power was one of the first 15 Benefit Corporations in California. This means our priorities are “People, Planet, and Prosperity.”

B Corp certification is like an organic produce certification for sustainable businesses.  It is Patagonia versus Walmart.  If you vote with your dollars and care about social and environmental issues, do business with B Corps and become a part of the solution!

Benefit Corporations are required to create a material positive impact on society and the environment. They are expected to meet the highest standards of social and environmental performance, transparency, and most importantly, accountability. They are also required to measure and report on the corporation’s impact on employees, suppliers, community, customers and the environment. Learn more at B Lab’s Benefit Corp Information Center.


Sun Light & Power was honored as Best for the World!  Visit the press release.

Meet Our Volunteers

The Mission of Sun Light & Power is to create a living environment that serves people’s intrinsic needs, supports the human spirit and preserves the planet’s resources for future generations.

As both a California Benefit Corporation (an alternative form of legal incorporation that enables for-profit entities to integrate social and environmental goals into their business operations) and a certified B Corp, SLP believes the power of business can be used to tackle important social and environmental problems. We strive to be good corporate citizens. Not only do we support philanthropic events and organizations, we are hands on with community.

Here are just a few activities our team has engaged in recently with their dedicated “Volunteer Paid Time Off” hours.

Travis – Design Engineer

Travis traveled to the Aqua Fri village in Nicaragua to install solar with Grid Alternatives. The 150 person village consisted of 1-2  room dwellings mostly made of sticks and mud with dirt floors.  There was no electricity. A few families had little 10W solar panels connected to a motorcycle size battery and had one or two lights.

His team installed a 1kW solar array on the metal roof and an inverter, charge controller, load center and battery bank to go with it. Since there was no place for the electricity to be used,  they installed a distribution system to get power to all three buildings and installed plugs and LED lights in all buildings.

Jon – Project Manager

Jon helped construct affordable housing with Habitat for Humanity at the Muir Ridge Development in Martinez, CA.  He spent the majority of the day with a crew of 4 folks schlepping 5/8 inch drywall through second floor windows and staging throughout the different rooms.  “It was a dirty, challenging, slightly dangerous and an extremely fun experience.  I was able to utilize muscles I didn’t know existed and meet cool people from all over the country,” Jon stated.


Blake – Director of Engineering

Blake saves lives through the Bay Area Mountain Rescue Unit. He has also volunteered for the National Park Service in Alaska’s Denali National Park, where he completed two month long mountain rescue patrols on the Ruth Glacier and on Denali itself.  His most recent rescue involved a an injured woman who fell off a cliff. She had been alone for 9 days in the Sierra National Forest location.



Erinne Davis – Project Manager

Erinne spent a morning with Save the Bay, working on a community project to restore and rejuvenate the native plants of the MLK Shoreline in Oakland.   “It felt so good to work outside in the sun and the soil, giving my day’s labor back to the ground,” Erinne reported.
