621 Energy developed a 41 kW roof-mounted solar photovoltaic (PV) project at the Becket-Chimney Corners YMCA Camp in Becket, MA.  The system was installed with no up-front cost to the YMCA. The YMCA signed a long-term Power Purchase Agreement (PPA) to purchase all the solar-generated electricity.

Becket-Chimney Corners YMCA Camp includes over 140 structures and 1400 acres. The camp serves over 1100 summer campers. The Berkshire Outdoor Center provides adventure leadership programming to 14,000 individuals annually.

The PV projects were installed on two buildings: the Chimney Corners Dining Hall and a newly constructed Facility Building. Both systems are connected “behind the meter” and are estimated to produce 44,000 kWh of electricity annually.

The Dining Hall system includes 90 ReneSola 255-watt modules, a SnapNRack mounting system, two Power One 10 kW inverters and a Solar Log monitoring system with a color graphic wall-mounted display that the campers can interact with.

The Facility Building system includes 72 ReneSola 245-watt modules, a SnapNRack mounting system, two Solectria 7.5 kW inverters and a basic Solar Log monitoring system.

The completion of the PV projects enabled the camp to significantly reduce the electricity usage of the Dining Hall and fully offset the electricity usage in the new Facility Building. The PV project provides progress toward the camp’s long-term goals of implementing sustainable practices and decreasing its carbon footprint.
