603 Solar Showroom

603 Solar is a solar energy service based in Stratham, NH. We wanted to begin a solar company structured on the values of integrity and honesty, providing an amazing customer experience and getting people the best return on investment. We pride ourselves on our educative approach to showing people the advantages of solar as there are many factors that go into designing a system that is tailored to your exact needs. Each home uses a different amount of electricity and has different concerns regarding shading and orientation. The world of solar can be intimidating and confusing.    That is where we come in. Our team of experienced solar professionals will come to your home and take a look at your situation to see exactly how solar could work for you. We then design your system, get permit and interconnection approval, coordinate the installation and monitor the system once it’s powered on! With over 15 combined years of experience in the solar industry, 603 Solar truly understands how to get homeowners the best return on investment. Call us today to see how solar can work for you!
