I got a small residential rooftop solar system installed by Alder and they were great. In the sales process, they were very professional and attentive to any questions I had. Communication was good while the system was getting permitted and while we scheduled our installation. The installation went smoothly and the crew was friendly. I got the system turned on quickly after installation and I am now producing my own power and it feels great.
