“After discussions with other solar energy system installers, we chose RCC Solar, based on great recommendations as well as price, and it was was an impressive experience from our initial meeting, all the way to any follow-up questions that we had. The owner, Roberto Helmeyer, gave us quite an education on solar energy as well, as he is an electrical engineer. He delivered our 45 panel solar panel system ahead of schedule, supervised every step of the process, and was always responsive to our needs. We could not be more pleased with his company and our new system. Our Duke Energy bill was $12.60, their minimum administration charge, during the first month after the installation. We also get credit for the energy we put back into the grid. What a joy to see our electric meter turning backwards! Also importantly, there are significant tax credits to be earned with the installation of a solar energy system. If you are thinking about going solar,We highly recommend RCC Solar.”

“RC Construction Solar installed our 7.5kW solar system in September 2016. The installation of 30 solar panels and associated equipment was completed in three days, on schedule, and in a very professional manner. Roberto, the owner, is a perfectionist and takes great care over all the details. I particularly appreciated the time Roberto took on his first visit to our house in Clemson to explain the process of getting all the necessary approvals and permits required for residential.solar systems in South Carolina even before I had selected him as my contractor. He took care of all the paperwork and the process ran very smoothly exactly as he had explained it to me. There were no surprises or problems. I would highly recommend RC Construction Solar for installation of residential solar systems in South Carolina.”
