I found this company online and decided to give them a try. I was not expecting much, maybe numerous phone calls or solicitations, and I am pleased to say this was a great experience. I gave EnergySage (ES) a few details on my solar needs and basic information. Their claim was, they would solicit vendors, vet them, and send a list of suggested vendors with detailed information on my system. I was able to then compare the on one chart to assist in my review. They set up a Market Place (portal) for me to use to communicate with vendors. I was able to get 6 companies to bid on the project and quickly narrowed it down to 3. I would send my questions through the portal and get responses back. The vendors did not have my phone or email information. This allowed me to control the flow. I had several questions during the review process and ES was able to answer my questions and assisted in my research. I was able to get the list to 2 and finally selected my vendor. I did not take the lowest estimate as I could compare all the equipment being used, company information and responses from vendors which assisted in my final decision. I am giving the service a 5 Star rating as I have been completely satisfied with the first stage of going solar. I was assigned a contact at ES and that person took very good care of me. I have just entered into a contract and hope for a smooth installation.
