Energysage really did not help us at all. The quotes we received from all solar vendors were tentative estimates at best and basically changed immediately by thousands of dollars once we got into further discussions with each company. The solar advisor from each company that works with Energysage is not the solar advisor you ultimately deal with so there is no personal concierge that EnergySage offers to be. That defeats the whole purpose of a one-stop shop like this touted to be. Energysage was good for basic information but is not worth using. You're better off contacting the solar company directly to get accurate quotes and assistance when planning your solar project.
