NORTHBRIDGE 2.6-MW SOLAR PROJECT

Northbridge, Massachusetts

Mass. Electric Construction Co. (MEC) crews installed a 2.6-MW ground-mounted solar photovoltaic system in Northbridge, MA, on a site previously used for farmland. Working as a subcontractor to Gehrlicher Solar America Corp., MEC installed a total of 9,064 solar modules, which included:

• 7,722 YINGLI 290W panels
• 1,342 SUNTECH 280W panels
• 46 rows of racking using an RBI ground-mount system
• 1,184 posts
• 2,368 top chords
• 4,548 z-purlins
• 620 cross braces
• 38 Shoals combiner boxes
• 4 inverters
• 2- skids
• 19,350 linear feet of underground conduit
• 21,080 linear feet of feeder cable

MEC also installed an Electro Industries data acquisition system to monitor electrical output and serves as a first warning against any potential failure in the solar system.

At the peak of the project, MEC worked with a crew of 30 union electricians from IBEW Locals 96 & 103.
