Lighthouse Electrical Completes MWRA Deer Isnald 180kw Solar Project

February 15, 2010

Lighthouse Electrical Contracting, a NECA Boston Chapter firm, completed the design/build $1.1M 180kW photovoltaic solar project at Deer Island’s water treatment facility for the MWRA in January 2010. The company specified and installed a modular SunPower® PowerGuard® photovoltaic system comprised of 592 305W solar panels on the 75,000 sq. ft. roof of the Deer Island MWRA Warehouse/Maintenance building. The array covers approximately 13,000 sq. ft. The energy efficient SunPower® system is designed to lay flat on the roof, maximizing the system size. A foam blocking feature will protect the roof and help insulate the building. The system’s R-10 insulation rating will save up to 30% additional energy by reducing the building’s heating and cooling loads. The SunPower system also was specified for its high wind resistance feature as it is able to withstand winds to 140 mph.

Project Managers Scott Sullivan, Newell Thomas, and Foreman Justin Aikens supervised the field crew of 6 electricians from IBEW Local 103 in the fast-track project. Lighthouse handled design/build project services with Stephen Kelleher Architects of Fairhaven and Art Engineering of Worcester. Both firms served as subcontractors to Lighthouse Electrical.
