"My fellow Americans, ask not what your country can do for you -- ask what can you do for your country." from President John F. Kennedy's 1961 Inaugural Address

On 15 May 2009, NH Public Radio recorded a spot on our solar panels for a series on "Alternative Energy."

On 22 December 2010, we were designated an "Environmental Champion" in the New Hampshire Sustainable Lodging & Restaurant Program, scoring 240 points (150 points are required to qualify), based on our Strategic Sustainability Plan and Policies.

On 29 February 2008, groSolar of White River Junction, VT, completed the installation of a 20 panel (3,600 watts) photovoltaic (PV) solar panel array on our tractor barn.

The array, as installed, is capable of producing an average of 348 kilowatt hours of electricity per month--approximately 43% of our average monthly electrical usage. If more power is produced that is being consumed, the excess power flows back through the meter into the Public Service of New Hampshire (PSNH) system, reducing our electrical bill through a process called "net metering."

See our monthly production charts and monthly cost table below.

On 18 March 2009, Minuteman Plumbing & Heating of Meredith, NH, installed a three panel thermal hot water system. The panels supply domestic hot water to a 135 gallon storage tank.

On 11 March 2009, groSolar completed the installation of a 24 panel (4,680 watts) photovoltaic (PV) solar panel array on our main roof.

The array, as installed, is capable of producing an average of 455 kilowatt hours of electricity per month.

See our monthly production charts and monthly cost table below.
