Get competing solar quotes online

The City of Cambridge has teamed up with EnergySage to light up our homes with solar power

It's the Cambridge Year of Solar! Sunny Cambridge is the city-wide initiative to make it easy for all types of residents to get solar power for their homes.

Solar is a smart choice for our community--not only is it clean energy, it also provides significant long-term savings. With financial incentives running out and Cambridge racing to reduce its energy use the most this year to win the Georgetown Prize, there will never be a better time to go solar!

Sunny Cambridge has lined up local solar installers through the EnergySage Solar Marketplace, which helps you request, receive, and compare solar quotes 100% online, with support available every step of the way.
