Exeter, New Hampshire - Combo Solar Hot Water and Solar Power

As they prepared for a move into a new home in Exeter, Eric and Cammie Savage considered a lifetime of energy costs associated with a home in New Hampshire’s climate.

A typical oil boiler needs 200 – 300 gallons of heating oil just to make hot water all summer.

As a result, it sends about 6,200 pounds of CO2 into the atmosphere, and between $600 to $1000 out the window. Typical electrical bills account for another $1500 and 10,000 pounds of CO2 annually.

The Savages asked ReVision Energy to collaborate with their construction team, including local green builder Chinburg Builders to integrate both solar hot water (SHW) and solar photovoltaic (PV) systems into the project. The closed-loop solar hot water heater is actually backed up by an electric element, which benefits from the energy generated by the solar electric. In the summer months, the 3.0 kilowatt PV array will produce enough electricity to send a surplus back into the utility grid for a net metering credit.

State and federal incentives for renewable energy contributed roughly 49% of the costs of the systems.

“The bottom line is, even without incentives, the solar hot water and PV systems cost less in the long-run (about 15 years) than using fossil-based energy” says NH Branch manager and technician Will Kessler, “It’s a pretty simple and environmentally sound decision.”

ReVision Energy wishes the Savages well in their new home!
