Choose the Best Path for You

Community Solar: Be a Host!

Our simplest option with high impact- host a solar system on your roof and send clean energy credits to low-income customers. A third party owns the system so there are no costs to the building owner. Simply enjoy earning monthly payments and know you’re helping your community and the environment.

Direct Purchase

Purchase and own the solar system yourself. This option provides the highest long-term savings. Where applicable, we can work with you to secure grants & loans to help cover upfront costs.

Power Purchase Agreement

A third party owns the solar system and you purchase the electricity produced at a discounted rate. No upfront cost or ongoing maintenance, just discounted clean energy to save you money on your bill. 

Program Eligibility

The City of Cambridge’s Solar Assistance Program is designed to support commercial and large residential property owners interested in installing solar on their buildings.

If your property does not meet the eligibility criteria for this program, we will connect you with another provider.
