Solar Quotes are efficient and helpful. The problem lies with the installer quotes. They lack detail, particularly they fail to itemize components, and quantities and available features. The efficiency factors they use vary from 70 to 85% without explanation. Most fail to consider shading issues fully. Most quote top end components without fully justifying their features. Most give little detail on the mounting components. None itemize labor costs. Some simply supply component specs without identifying warranty arrangements. None fully list the monitoring features.
