Solar Panels in Littleton, NH

Littleton, New Hampshire residents are served by Littleton Water & Light Department, which charges $0.16 per kWh for residential electricity. This is 4% below the national average of $0.168/kWh. At this rate, a typical household using 900 kWh per month spends approximately $1,749 per year on electricity—money that could be going toward building equity in a solar system instead.

An 8 kW solar system in Littleton can offset most or all of a typical home’s electricity usage, saving approximately $1,554 per year. Over the 25-year lifespan of the system, that adds up to $56,666 in total savings. The estimated payback period is 16.1 years.

As a municipal utility, Littleton Water & Light Department sets its own rates and rebate programs independently. Net metering is available, meaning excess solar energy you produce earns bill credits from Littleton Water & Light Department. Heat pump rebates of up to $500 are also available for Littleton homeowners.

The federal residential solar tax credit (Section 25D) expired at the end of 2025, making state and utility incentives more important than ever.
