Very happy with EnergySage and the EnergySage process. I was able to narrow the proposals down to three and then after talking with those three I had two that came out to the house to confirm their proposals. EnergySage had a nice summary of the proposals and good additional information on the different components, in addition to the reviews of the installers. The EnergySage rep was helpful in answering my questions. I ended up with a 10kW system plus three Enphase batteries and have been very happy with the sytem so far and got my first 'Nothing Due' bill from Eversource the other day. The batteries were primarily to provide whole house emergency backup (ended up similar cost as a generator - there are some things to consider with each). I haven't had a major power outage yet but I tested it for a half a day and ran what I needed to. The couple times the power when out for a short period we didn't even know the power went out. The Enphase system has a great integrated system for the use of the batteries and the solar system. One warning is my local Town ended up requiring a room around the batteries in my basement for fire protection. My installer handled it but it was an unexpected hassle. Different Towns may have different requirements so be sure to ask. I signed up for Eversource's Conected Solutions Program which pays me to use my batteries during peak electrical use during the summer. I hadn't planned on that but it was a nice bonus to help pay back the system. Its limited to certain areas and certain batteries so be sure to check. I've also signed up for Renewable Energy Credits, which was a bit of a hassle to sign up for and is not a lot of money but again will help with payback. Overall I am happy with EnergySage and my solar project.
