621 Energy a True Partner

First Congregational Church in Melrose selected 621 Energy after careful review of 6 quotes provided by EnergySage. 621 Energy was responsive to the needs (and sometimes delays) of a non-profit, worked with us to get the best offer to our capital campaign committee, and once a contract was signed moved quickly through a very rainy fall to install our system. They have proven to be a true partner to our organization.

Energy Sage put me in touch with many possible vendors, but it was Bob Clarke of 621 Energy who was ready and able to make our installation possible. He knew what questions to ask, could easily explain what would be possible, and helped us succeed in getting our installation to happen - 40kw 5-pole mounted trackers.
