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.
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.
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.
