I interviewed a couple of solar companies, and this is the only one who sent the engineer out the first time, so he was able to look at my place and actually tell me what kind of system would work best for me. The other companies sent a salesman and wanted me to sign a contract BEFORE even learning what I needed or could accommodate. And their price was less than half that of the leading competitor. The system went in quickly, all of the workers were very friendly and professional, and I'm thrilled with the system. SunRiver Solar is wonderful.
