What Our Clients Think

Randi Sundby

Wonderful experience, the crew was friendly, professional and efficient. We love our solar panels and highly recommend this company!

Rick Lippold

I had a very positive experience working with Sphere Solar.
Regarding the contract they did what they said they would do for the price quoted. The work appeared to me to be quality and the solar array has been functioning with no issues.
I enjoyed working with the Solar office staff of Mia and Maria, they were helpful, responsive, and friendly. I also enjoyed working with the installation crew, especially electrician Peter who was not bothered by my many questions.
My impression is that Sphere Solar has a higher goal than just making a profit, but rather doing the right thing by providing a service of installing solar to the benefit of our home planet.

10% of All Profits Are Donated to Sphere One

The founder of Sphere Solar Energy, Edwin Wanji, grew up in Kenya and saw first-hand how clean energy technology can drastically increase the prospects of marginalized communities. He started Sphere Solar Energy in order to give back to these communities. And he is committed to elevating their voices so that they are not only passive beneficiaries of the clean energy revolution, but also key contributors to its growth.
