Hans was very patient because we had many questions about solar; he did a wonderful job explaining the system to us during the evaluation. The two guys who installed our solar electric system were incredible. We’ve had many contractors in our home and none of them were as neat and professional as the ReVision crew. They cleaned up every last bit at the end of the job and left us with a high quality solar energy system – we love watching the inverter to see how much clean solar electricity we are making each day.
