Another positive experience with Stellar Solar. They installed solar on our old house in 2015 so when we moved this summer, they were the first call we made. Once again, Marc Cirelli provided excellent customer service. I told him I wanted to move quickly and he made it happen. The install was quick and painless and we received our permission to operate yesterday. For reference, I have neighbors who contracted with other companies well before I did and they're still waiting for an install date. Highly recommended. If we move again, Marc will be the first person I call.

They then proceeded to tell us that we were being charged because we own the solar panels and if we leased them, this charge would be voided. We are in Real Estate and have a lot of friends who intall solar and when we talked to them about this fee, they were shocked. The fee was not negotiable and we were stuck either with wither never having our solar monitored or paying 300$ for someone to come connect to our internet, which we could do ourselves since we connected our own internet with extenders. So, all in all, not a great experience unless you were the original purchasers of the solar
