President Jeff Wilson and I interviewed a number of companies before deciding on Cool Earth Solar to help us transition to renewable energy. After meeting with their CEO, Rob Lamkin, the choice was easy, and we’ve never looked back.”- Dave Johnston, General Manager, Toyota VallejoLEARN MORE

Bankhead Theater

“
As a nonprofit organization, acquiring solar was a way to save costs and redirect some of our resources to serving our mission (and lowering our carbon footprint). Cool Earth Solar was extremely helpful in working with us to find the best savings and navigate the very complex energy market. They stayed with us all the way from the initial call through the entire process in getting our power switched over. They continue to stay in touch and make sure we are taking advantage of all the programs and opportunities available. Rob and Rebekah and the whole team are responsive and easy to work with. I would highly recommend them!”- Chris Carter, Executive Director, Livermore Valley Performing Arts CenterLEARN MORE

York Project

“
... from the first few minutes of contact with Joshua I knew things were different than the other companies I talked to. These people not only know their stuff and make the whole process effortless but they treat you like friends. Communication from Joshua and Rebekah in the office was over and above what you would expect from a company. My experience with Cool Earth only got better and better as time went on. From Joshua and Rebekah to the electricians and installers I cant say enough good things. I had 3 other family members go with Cool Earth because of the personal support and care they give to every customer...”- Steve LEARN MORE
