Enphase Energy Inc., www.enphase.com, Petaluma, Calif., and My Generation Energy Inc., www.mygenerationenergy.com, South Denis, Mass., a solar installer and developer, have announced the completion and commissioning of the Sippican Community Solar Garden in Marion, Mass.

The 900-kilowatt-DC commercial project is the largest North American installation to date featuring the advanced Enphase C250 Microinverter System.

My Generation began construction on the site in January 2015. The installation, which features more than 3,200 Enphase C250 microinverters and LG Solar photovoltaic modules integrated onto a Unirac ground-mount array, was completed and interconnected to the grid in April.

With the electricity benefits enjoyed by more than 100 members of a nonprofit consumer cooperative, the net-metered Sippican Community Solar Garden facility is expected to generate more than 1,200 megawatt-hours per year. Suntility Electric, www.suntilityelectric.com, a renewable energy services company, and My Generation operate and maintain the array as well as managing its net metering credit allocations to the cooperative.

Luke Hinkle, manager, Suntility Electric, and founder of My Generation Energy, says the Enphase commercial system provided significant cost, labor-saving, and performance benefits to the Sippican project.

For a large-scale commercial project like Sippican Community Solar Garden, the reduction in the levelized cost of energy provided by the optimized Enphase C250 platform will improve the economics over the project’s lifetime, says Jeff Loebbaka, senior vice president of global sales, marketing and support, Enphase.
