Pepperell Mill Campus Solar – Biddeford, Maine
1,192-panel solar array at renovated mill at Saco Falls – Biddeford, Maine.
Sanford said he will invest up to $1 million in the project, but the final cost has not been determined. The project will pay for itself within 10 years. Sanford plans to leverage federal tax credits available for solar projects.
The 1,192-panel solar array spread over 1.5 acres of rooftop will produce 437,320 kilowatt hours of energy annually, more than enough electricity to meet the needs of the campus’s 100 residential units. The remaining electricity generated by the solar array will be allotted to the 51 new apartments currently under construction and due to come online next spring.
The array will result in annual carbon offsets of approximately 460,498 pounds per year, the equivalent of the annual greenhouse gas emissions from 40 passenger cars driven for one year or 500 barrels of oil.
Sanford said if the project works out as predicted, he plans to expand the system over more of the 12 acres of flat roofs at the complex. He also would like to partner with neighboring mill owners and create a renewable energy district.
