Penobscot Solar Design

Penobscot Solar Design has been installing quality solar photovoltaic (electric) systems in Maine and throughout New England since 1988. We have been installing those same systems throughout the Caribbean since 1998.

We specialize in off grid systems and large utility intertie systems, but whatever your needs, we have the solar solution and the knowledge, experience and expertise to make you another of our many happy customers. Our owner, designer and head installer, Daryl DeJoy, has been NABCEP Certified since 2006. All the people who will install your solar system not only work with, but also live with, solar power in their homes. We believe in what we do and install each system as if it were our own. We are a small company and treat each customer as if they are our only customer, and with over 350 installed solar systems under our belt, performance and longevity are assured. Please browse our website as it will help guide you through the initial process of deciding which type of PV system is best for your needs and don’t hesitate to give us a call or email with any questions!
