The only rooftop site in the solar plan, our Sutton/Northbridge site is located on top of a distribution center on Main Street, located on the town line between Sutton and Northbridge. The rooftop design allows us to avoid using excessive land which could be used for other purposes and shows us the advantages and issues associated with rooftop mounted solar generation. We received regulatory approval for the project in October of 2009 and construction of this site was completed at the end of May 2010. The Ribbon Cutting Ceremony, held on May 27, 2010, marked the first day of solar generation for the site. The project is currently up and running.
Construction of this project is estimated to save 2,800 pounds of sulfur dioxide, 1,300 pounds of nitrous oxides, and 1.3 million pounds of carbon dioxide per year. This is equivalent to the emissions produced in generating electricity for 200 average homes.
On this per year basis, the 1.3 million lbs of carbon taken out of the atmosphere is the equivalent of removing more than 124 passenger cars from the road; eliminating the CO2 emissions from burning 3.4 railcars of coal; or reducing the CO2 emissions from burning approximately 1,500 barrels of oil.
This project is designed to generate 983 kW of DC power, accounting for approximately 1,148,560 kilowatt-hours per year. This is produced from 4,683 panels spanning over 2 acres. Laid end to end, the panels would stretch to cover nearly 5 miles. The panels are mounted on the roof with a fixed inclination and position.
