Carlson Orchards, Harvard MA – 220kW P/V Ground Mount System – Lighthouse Electrical has completed the installation of a 220 kW ground-mount PV system at Carlson Orchards in Harvard, MA. The Rockland, MA based NECA contractor’s field crew of 8-10 electricians from IBEW Local 103 provided Massachusetts largest agricultural solar installation project in a 3-month project schedule. The system consisted of 1,050 Evergreen 210W solar panels. Evergreen Solar is a Massachusetts based solar manufacturer. The system features a data acquisition system by Massachusetts based Solectria Renewables. Design was provided by Stephen Kelleher Architects of Fairhaven, MA under subcontract to Lighthouse Electrical. Project power generation from the system is expected to save approximately 75 percent of Carlson Orchards electrical costs, largely refrigeration units that chill and preserve harvested apples.
