While I found the information useful and valuable, as well as finding several solar installers worthy of consideration, the EnergySage quoting system is rather devious and misleading. It takes an inordinate amount of effort to find out what the system you are looking at will REALLY cost. They spend all of their energy and format everything to try to make a sale. All they present are "cost savings," "payback period" and "net cost after rebates and tax incentives." But they hide the actual total cost under 2-3 levels of click throughs. I find this very decieving and misleading. It is almost as bad as the hidden "resort fees" that hotels try to hide from you when you search for a room. In summary, I was able to wade through the process and EnergySage definitely helped me find what I hope will be the right installer, but their process and format do not serve the customer ... only the installers by hiding the true cost of the system deep in the bowels of their system.
