We are still working through the stages of our project. Waiting for the permits and then installation of the system. We are using Ace Solar and found them to have the best combination of quality products, sales rep communication (Deano), and cost. The system that EnergySage has developed allows, in my judgement, a great service of unbiased product reviews, efficient communication with multiple solar companies, advice re getting a fair contract, and PROTECTION against having a deluge of calls and messages from providers that are difficult or impossible to compare. They require a basic information template from any participating company to allow confident decision-making. I used email communication with EnergySage first, then scheduled phone calls--both of which were very easy and smooth to use. Joe Fonseca was my contact person at EnergySage.
