Solar Calculator


New Hampshire Electric Cooperative supports the development of renewable generation by our members. By installing a solar PV system, you can serve your home with renewable energy. If your solar PV system generates more energy than you consume, you will be compensated for any energy you export to the grid. As a member-owned non-profit, our exported energy rates are based upon the money you save our membership by not having to purchase energy.


We have developed this simple solar calculator so that you can calculate your savings by using solar.
