GreenField Solar

What GreenField Solar does

GreenField Solar (previously Solar Store of Greenfield) is a privately held solar PV design and installation company headquartered in Greenfield, Massachusetts, serving residential, commercial, and municipal customers across more than 85 municipalities in Western Massachusetts. Founded in 2005 and operating under current ownership since 2008, the company has completed over 500 installations representing more than 2 MW of installed PV capacity as of the most recent reporting.

The company's core product offering is turnkey solar PV installation spanning roof-mounted, pole-mounted, ground-mounted, and AllEarth dual-axis tracker configurations, with GPS-based dual-axis trackers producing 40% more energy than roof-mounted systems. GreenField Solar is a premier AllEarth Renewable dealer since 2016 and an authorized installer for REC, Panasonic, SMA, SolarEdge, IronRidge, and MT Solar equipment. Adjacent offerings include battery backup and storage, EV charger installation, solar hot water, air source heat pump electrification, and Sun-Mar composting toilets, supported by ongoing operations and maintenance services that are also available to systems purchased elsewhere. Customer economics are anchored in the 26% federal Residential Renewable Energy Tax Credit, a 15% Massachusetts state credit (capped at $1,000), net metering credits, Class 1 REC quarterly payments, and a financing partnership with UMass Five College Credit Union offering loans up to $75,000.

The business operates on a direct, field-sales go-to-market: founder John Ward conducts on-site assessments, after which contracts run from design and siting through interconnection, permitting, financing, incentives, and final inspection. Revenue streams include one-time project installation (hardware sales plus labor), with a smaller recurring O&M services tail. Pricing is not publicly disclosed. The company is led by John Ward and Claire Chang (30+ years of combined solar experience and active in Massachusetts distributed-solar policy advocacy) with Stephanie Williams handling monitoring, design, and technical support since 2016. Ownership is independent with no parent company, subsidiaries, or external institutional capital identified.
