Reviews

Becky LaBlanc-Willis

Following a disastrous experience with another local company, we turned to Cromwell for our residential Generac generator installation. Everyone we dealt with--from start to finish--was professional, knowledgeable, and super to work with. They handled the permitting process and coordinated with the local electrical company and propane provider. The entire project would have been completed in about 60 days if the propane company hadn’t caused a delay. We will have Cromwell out every year to service our generator and we will toast the entire crew with a hot cup of tea every time the power goes out (which is unfortunately a lot). Thank you, friends at Cromwell, for your hard work and kindness.

I recently had Powerwalls installed in my home and though my past experience with your company gave me expectations for professional service, I was especially pleased with the professionalism, thoroughness and willingness to answer all of my questions demonstrated by all of your team from Bill, Yasmine, Sara and Jesse to Angelo and Tucker as well as all others that I encountered. As for the installation, I cannot say enough great things about Angelo and Tucker. I respected the tight timelines that they were working under, but they still managed to always be friendly and responsive to my needs. You can bet that I will continue to look toward your company for addressing all of my future green energy needs!

Working with Cromwell Solar has been an outstanding experience from start to finish. Their staff—(especially Bill, Yasmine, and Angelo)—were professional, knowledgeable, and a pleasure to work with. Everything about our project went smoothly, and they took the time to walk us through important details, including information on available tax incentives. The results speak for themselves: in our very first month of operation, our utility bill dropped by nearly 70%. That kind of savings allows us, as a nonprofit, to reinvest more of our resources into our mission-driven work supporting individuals with intellectual and developmental disabilities. We couldn’t be more pleased with the process and outcome, and we highly recommend Cromwell Solar to any organization or individual considering renewable energy.
