Eversource Energy (NH) charges $0.20/kWh today. With solar + battery, you lock in energy costs and protect against future rate hikes.
Hollis, New Hampshire residents pay $0.20 per kWh with Eversource Energy (NH), which is 16% above the national average. At this rate, a typical household spends approximately $2,106 per year on electricity. A combined solar + battery system generates clean energy during the day, stores the excess, and powers your home around the clock—dramatically reducing or eliminating your Eversource Energy (NH) bill.
A battery stores excess solar energy generated during the day for use at night and during outages. New Hampshire averages 10 hours of power outages per year, making battery backup a practical investment for Hollis homeowners. When paired with solar panels, battery storage maximizes self-consumption and reduces grid dependence.
