We are thoroughly satisfied with our SunPower system and the service E2 Solar has and continues to provide. From their initial sales presentation, to system design, installation and finally management of all system registration and startup requirements E2 Solar stands out as the best there is. You will not find a more accommodating and friendly group of folks who are truly there to support you from your initial decision-making process through to system operation and after. Never was there any pressure to purchase, rather, they have always been there to help.

Anyone considering the installation of solar panels on Cape Cod should very carefully evaluate both the the company AND, most importantly, the product itself. Performing your due diligence provides more than peace of mind; it will clearly show you that one product is vastly superior to anything else on the market. That product is the American-made panel produced by SUN POWER. Further investigation will confirm that E2-SOLAR of Dennis, is the only company to manage your project. The combination of E-2 and SUNPOWER will be one of the best investments you ever make!

Stellar customer service is not a term I have used very often but in the case of Desiree at E2 Solar and her team of associates, its the first thought that comes to mind. I researched 3 other companies who offered less expensive solutions and there is no doubt that had I signed up, I would have received a less than satisfactory outcome. I couldn't be more thrilled with this exceptional company and I'm reaping the payback over and above my expectations.
