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

This passive solar house in Portsmouth, New Hampshire has a 3.4 kilowatt Sun Power photovoltaic (PV) array mounted on a 40-degree pitched roof, and a Sun Power 3000 inverter.

The solar electric array generates most of home’s electricity during the course of the year, averaging about 380 kilowatt hours each month.

This solar power system is grid-tied with no moving parts and smart inverter technology that allows the import of electricity to the electric panel on overcast days or when electric load is high. In clear sunlit conditions the array will export energy out to the electric grid, and credit is banked under New Hampshire’s net metering program.

Using solar power at home not only produces clean energy reliably, it reduces the strain on the electrical grid during times of peak demand.  Since solar energy has no emissions, this system will eliminate an estimated 6,890 lbs of CO2 from the atmosphere each year!
