Lease / Buy / Choose a Solar Installer

You can choose to either purchase or lease a solar PV system.

Leasing a System

If you choose to lease a system, a solar company installs the system on your property for little or no upfront cost to you. They own and operate the system. You pay them a monthly equipment lease fee which is less than what you would have paid CMLP, on average, to deliver the same amount of electricity to your house. One caveat: the lease agreement must be approved by CMLP’s legal counsel in advance. To date, they have approved lease agreements offered by Direct Energy / Astrum Solar and New England Clean Energy – the only two that have submitted agreements for approval. 

Owning a System

General information about system installation costs can be found here:  Residents can get loan assistance from MassCEC.  You can find information about the federal tax credits for solar PV installations here: and state tax credits here:

PV Installers

Regardless of whether you lease or purchase a solar array, you'll need to choose a company to work with.  CMLP recommends getting 3 quotes for any significant work you have done on your house.  We do not have a list of pre-screened solar contractors, but you can find some through the following avenues:
