The sales pitch, detailed but NOT overwhelming. If you want details on inverters and redundancy Kevin knows it. The installation of the solar panels was faster than we could have imagined. They were down a man and weather was looming, but the crew (Jeff and Jesse) was so good, and the system was streamlined so well, they finished early. The panels were commissioned and working on day 3. We couldn't be any happier with a company's professionalism and commitment to service.
