In 2006, we installed a solar ground-mounted array and a roof-mounted array on the top of our camp building.
Combined, these arrays produce 21 kW and reduce the electricity the sanctuary draws from the public electric provider. This has allowed us to take a dramatic step toward energy self-reliance.
The Pole Barn has 12 SunPower panels with an estimated production of 4,935 kWh.
The Property Manager's House has 18 SunPower panels with an estimated production of 7,418 kWh.
In the spring of 2010 Wellfleet installed solar thermal systems for the campground, dormitories and nature center to cover all of its domestic hot water needs.
