Renewable/Solar (PV)

This is a partial list of recent Lighthouse Electrical Renewable/Solar (PV) projects. Click project name for further details and project photo(s).

Harvard University – Gordon Indoor Track

Installation of a 570 kW solar array at Harvard University’s Gordon Indoor Track facility.


Installation & ongoing maintenance of Photovoltaic system at numerous sites across MA.

Old Colony Phase I & II

2-phase solar installation for the Old Colony Housing Project in South Boston.

Walmart, Tewksbury, MA

Solar installation services at six WalMart stores throughout Massachusetts.

Methuen Landfill

Turn-key installation of PV system on existing landfill, including the modules & racking along with the installation & wiring with necessary conduits, grounding, inverters, 1000 KVA transformer, etc.

Mann Orchard

Installation of 108 kW solar (PV) system in Methuen, MA

Maverick Gardens

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

Massachusetts Water Resources Authority

180kW PV-solar design/build project at Deer Island’s water treatment facility in January 2010.

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.

Newton South High School

Newton South High School in Newton, MA.

Carlson Orchards

Project Details:

Lighthouse Electrical completed Massachusetts largest agricultural solar installation, a 220kW PV design-build project at Carlson Orchards in Harvard, MA in August 2010. The ground-mount solar array, comprised of 1,060 solar panels, which cover approximately two acres of the orchard, are tied in to two solar inverters. The PV system generates approximately 70% of the annual energy usage of the orchard, largely for refrigeration units used to chill and preserve harvested apples.
