In the beginning...

You could say the vision of Rooftop Solar is as old as the sun, but the passion for solar energy started when the Grandfather of founding Rooftop Solar partners Hadassah, Seth and Jason, first installed solar on his house. Grandpa Holland was a longtime believer in clean energy, well before there were government incentives and tax benefits. That passion stayed in the family. Finally, in 2008, after years of discussing the idea, the grandkids (all grown up and professional) decided to combine forces, passion and vision to create Rooftop Solar.

 

Today Rooftop Solar services Arizona and California by providing clean energy at an affordable price to private residences and commercial businesses.

 

Grandpa would be proud.

Seth, Hadassah, and Jason Holland, with their father, Larry.

...Through today.

What started as an idea fueled by passion has become the best solar company in the US! Ok maybe we’re a little bit biased, but Rooftop Solar is a community of individuals who care about the environment, the community and doing the right thing! In 2017, Rooftop Solar was invited to and became a partner of the well known Amicus Solar Cooperative.

 

Amicus Solar is a member-owned purchasing cooperative of over 55 high-quality, independent, values-driven solar energy companies. Amicus members share a unique mission-driven perspective on their work in the world, along with a willingness to openly and actively collaborate to help each other grow stronger and smarter. We’re in this to grow our collective positive impact, and by banding together we’re building great companies that will do that for many years to come.

 

With Rooftop Solar you get the expertise and support of one of America’s largest solar groups, while maintaining the family-owned, personalized attention of a home-town company. Can you feel the love?

“Rooftop installed a big ground mount solar unit for us. They used their magic box to determine ideal angles and location. Installation was completed last year and I haven't had any issues with it, but have been saving a bundle of $$ by replacing propane and gas (car) by switching cars and appliances to electric. It more than pays for my electric bill.”

- Andy V.


“Rooftop Solar has been extremely professional and timely. They took care of all the application/paperwork with the utility company. The process was simple thanks to Rooftop Solar. The staff was very helpful to all my many questions and emails, and always responded immediately. I couldn't recommend them highly enough.”

- Nicolaus H.


“We went solar with 27 panels and couldn’t be happier. Rooftop Solar has been attentive to all of our concerns and the system has worked without fail. I would recommend Rooftop Solar for all solar jobs regardless of the size, this company is more than prepared.”

- Megan S
