The American Solar Energy Association's National Solar Tours will be held around the country in October. Locally, Trudy and Michael Mayhew at 60 Campbell St., as well as the Stone/Skinner residence at 117 Commercial St., in Boothbay Harbor will be hosting Solar Home Tours on the weekend of Oct. 5. These tours are open to the public and are free of charge.
This scenic area avoided a $19 million CMP Utility Distribution line upgrade by implementing energy conservation measures and adding distributed solar electric systems.
The Stone/Skinner residence will host their open house from 10 a.m. to noon Saturday, Oct. 5, and from 1-3 p.m. on Sunday, Oct 6. Their home has two, six-panel rooftop arrays (3.3 kWp system) that has been operational since Nov. 1, 2015. It has produced 3.7 mWh/yr., which meets most of their electric needs. This system was installed by Heliotropic Technologies. They also have a ground-mount 27 kWp system in Maryland that went online on Aug. 15, 2017.
The Mayhews’ solar home open house will be held on Saturday, Oct 5 from 11 a.m. until 3:30. p.m. This 2,950 square foot solar home has an attached greenhouse, solar hot water, solar hot air and solar electric systems. It is a demonstration of green building practices that includes a synergistic blend of an attached greenhouse with 1,000 gallon (thermal mass) pool, a radiant floor heating system on the lower level, a mini split dx heat pump on the second floor, and the solar air heating system on the third floor, inside of a super-insulated building envelope. The grounds have raised organic, produce and flower gardens, beer hops, apple, cherry and peach trees and is situated on an elevated location, with a south-facing harbor view. This home is a very close to net-zero energy, and is often net-zero electric. This 35-year work-in-progress is incrementally approaching net zero energy.
This tour is part of the American Solar Energy Association’s Solar Home Tour.
