System:
105.3 kW Grid-Tied PV System

Overview:
Worcester State College has joined the green revolution. WSC has a commitment to sustainability and has incorporated many upgrades and improvements into their overall sustainability plan, including the purchase of a biodiesel processor, conservation efforts and increased recycling. Another big part of their plan was installing a 105.3 kW solar array on their Learning Resource Center. The system was funded by IRS Clean Renewable Energy Bonds and a grant from the Massachusetts Technology Collaborative. The photovoltaic array will generate over 140,000 kilowatt hours of electricity annually, which is enough energy to supply electricity to 20 homes of about 2,800 square feet each.
The 540-panel installation was completed by groSolar in only three weeks while school was in session. It is the largest solar array on any college campus in Massachusetts and the largest in the city of Worcester.

System:
100.1 kW Grid-Tied PV System

Overview:
Green Mountain Coffee Roasters is helping to keep the Green Mountains green with a 100.1 kW solar array. This array becomes the largest photovoltaic array in the state of Vermont and was made possible through an innovative partnership between Green Mountain Coffee Roasters, the state of Vermont, Green Mountain Power and groSolar. groSolar CEO Jeff Wolfe says Vermont’s tax incentives for commercial solar systems, coupled with grants from the Vermont Department of Public Service’s Clean Energy Development Fund and Green Mountain Power, made the economies of a commercial system very attractive.
groSolar installed the system at GMCR’s Waterbury, VT headquarters using the PanelClaw flat roof mounting system. Although this system will produce only a small portion of the total electricity used by Green Mountain Coffee, it provides a look into what is possible for the future of energy.

System      
Solar Hot Water (SHW)

Overview
groSolar installed a SHW system in April of 2008. This system is tied to Fenway’s existing water system. The solar-heated water will supply the park and the restaurants on the lower levels of Fenway. “We are honored to assist Fenway and the City of Boston in their drive and determination to ‘turn Bean Town into Green Town’, as Mayor Menino so eloquently puts it.” says groSolar’s Marketing Director, Kelli Pippin. “Solar is our forte and it’s also the cleanest, greenest weapon we know of in the fight against global warming.

System
1.1 MW single axis, ground mount solar electric system

Overview
Mariani Packing Company wanted to install a solar electric system at their Vacaville, CA packing facility because it was fiscally sound and environmentally responsible. More importantly, it supported the company's values of continuous improvement and building for the future. SunEdison financed the system and will operate and maintain it.  SunEdison partnered with groSolar and Integrated Energy Systems who engineered and constructed the system in approximately 90 days. The system cost nothing to Mariani who, under a solar power services agreement (SPSA), purchases their solar electricity at long-term predictable rates euqal to or less than retail energy rates.

The 1.1 MW system sits on 7 acres of land owned by Mariani and will supply about 23% of the facility's electricity. Over 20 years it will produce enough energy to power 3,230 average U.S. homes for a year and offset more than 30.3 million pounds of carbon dioxide (equivalent to taking 2,972 cars off the road for a year).

821.5 kW grid-tied roof mount system at 7 different locations

Overview
Winn Development was looking to stabilize their utility costs and save energy for a number of their low income and senior housing communities throughout Connecticut and Massachusetts.  They came to groSolar with a very aggressive project deadline that needed to be met in order to obtain optimal financing.  821 kW as a whole is a large project but even larger when each individual property location (7 total) contains multiple systems (over 30). Winn not only had time restrictions but many of the locations were historic and needed to preserve the unique look of the building. groSolar was able to work quicky and efficiently to both meet Winn's timeline and keep the historic aesthetics of the buildings. 

Check out the actual power being produced at Mill Pond Village, one of the seven locations.

Overview
Soquel High School, a public high school serving 1200 students in Soquel, CA, had two main motivations for using the sun for electricity. First, financial incentives in California allowed the school to save money immediately. Second, going green was in line with the mission of the school to encourage students to responsibly contribute to society. The school set an example of social responsibility and was able to show the economic and environmental impacts of solar power. The solar array at Soquel High School is the largest solar PV project in Santa Cruz county and one of the largest school projects in California. The system is expected to produce approximately 40% of the school's electricity.

For students and teachers the solar installation offers a hands on learning experience in social, economic and environmental responsibility. Check out the actual power being produced by this system here.
