In 2007 Maple Hill Farm flipped the switch to what was at the time Maine’s largest solar energy array; one hundred, twenty-six 120-watt Evergreen solar electric panels were installed to total 15 kilowatts of solar energy. This system will produce on average 16,000 kilowatt hours of clean electricity each year. The solar electricity works in conjunction with a 10 kilowatt wind turbine to provide the Inn and Conference Center with a good portion of their electrical needs. A solar hot water system was also installed to heat large hot water storage tanks. There are 200 evacuated solar tubes on the roof providing enough hot water for the guests to shower, use the whirlpool tubs and for the needs of the kitchen facilities. Back up to the hot water comes from an efficient oil fired boiler. Maple Hill Farm, located on 130 acres neighboring our state capital, has earned a reputation as an environmental business leader. They were the first property in the state to receive the Green Lodging Inn Certification from the Maine Department of Environmental Protection.
