Harvard University – Gordon Indoor Track

Project Details:

Lighthouse Electrical served as the electrical contractor in providing labor, project management and photovoltaic (PV) system materials for the installation of a 570 kW solar array at Harvard University’s Gordon Indoor Track facility. The high-profile project had a very tight timeframe, and in meeting the aggressive schedule, Lighthouse supervised a skilled IBEW Local 103 electrical crew. The project scope included installation of the roof-mounted solar array and solar inverters. Lighthouse teamed closely with the general contractor and Harvard personnel, ensuring that stringent safety and all critical project requirements were met. The project was successfully completed and turned over to Harvard in under three months.

Old Colony Phase I & II

Project Details:

Revitalization of the Old Colony Housing Project in South Boston featured a 2-phase solar installation project.

In the first phase, Lighthouse installed 140kW of roof-mounted solar systems on five residential buildings. Three buildings were smaller pitched roof installations; the other two featuring ballasted roof-mount systems.

In the second phase, Lighthouse installed 90kW rooftop solar (PV) systems on two flat residential buildings. Both phases of the project were closely coordinated with the general contractor, as significant ongoing renovation work continued throughout the solar installation.

Special Project Challenge: Safety, as in all projects, was paramount. This project required special safety considerations and techniques. A combination of flagging, hard hand-rails and tie-off ropes were required to install the PV systems, as the roof-mounted arrays were designed outside the safe working area of the roofs.

The projects were completed on-time and without incident.

Walmart, Tewksbury, MA

Project Details:

Lighthouse was contracted by the system owner to provide solar installation services at six WalMart stores in Massachusetts. All six projects had very tight schedule requirements due to the Federal Tax Credit deadlines and implications on the financing. Lighthouse overcame permitting, delivery, utility and weather delays and was able to complete the solar projects and have them interconnected to the power grid in only three months, by December 31st, 2012, as scheduled. The dedicated Lighthouse team worked through severe weather conditions to have these projects on-line, as specified, turning over high quality solar installations to our client.

Maverick Gardens

Project Details:

Lighthouse was brought in to provide a turnkey price to incorporate solar onto this building. The solar modules are mounted to each parapet at a 30 degree angle facing due south for maximum solar energy capture. This system has fourteen individual inverters mounted behind the arrays.

The 112 solar modules collect energy and send it to the 14 inverters, which are in turn linked to the building’s power distribution system. The electricity is used immediately within the building or sold back to the electrical utility. In 2006, the set-up generated over 12,000 kilowatt-hours of energy and curbed the production of close to 17,000 pounds of carbon dioxide.

Massachusetts Water Resources Authority

Project Details:

Lighthouse Electrical completed the design/build 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 protects the roof and helps 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 up to 140 mph.

Project Managers, Scott Sullivan and Thomas Newell, and Foreman, Justin Aikens, supervised the field crew of 6 electricians from IBEW Local 103 in this 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.

Trolley Square, Cambridge, MA

Project Details:

The facility’s roof did not have a parapet, therefore a PV system with 120MPH certification had to be designed. Lighthouse Electrical Contracting, Inc. installed this system so that the entire roof was connected right up to the metal drip edge of the building. This Solar system is a perfect example of getting the most out of a challenging project with limited roof space. To further showcase this building’s commitment to Solar, Lighthouse installed a vertical system on the front of the building.
