From our first contact to today, we have been extremely pleased with RGS. The account rep worked overtime to get our application in on time to take advantage of the best program in MA. He provided all the information we needed, pleasantly answered all our questions, accurately explained the process, and even provided estimates of the amount of power we'd generate that have proved to be amazingly accurate. The installation process went smoothly - with the installers carefully assessing our roof strength and electrical panel adequacy to handle the system. We had a slight delay down the home stretch, which is the reason for only four stars in that category. We have called customer service a few times and they've always been friendly, responsive, and helpful. We love taking advantage of the sun and having a $1000+ credit with the electric company - we intentionally oversized our system. We couldn't be more happy and enthusiastically endorse RGS.
