Customers considering solar loan products may be directed to our Consumers and Residents section, which offers resources on solar financing as well as a list of lenders who participated in the Mass Solar Loan program.


Regarding Existing Mass Solar Loan Projects:

For projects within the program that have not yet been completed, installers should follow the steps below: 

  1. Proceed with constructing the solar project. Once the system is interconnected to the grid, installers will upload project completion documents to the Solar Loan Portal. Detailed instructions can be found in the Installer Portal Step-by-Step Instructions in the Installer Quick Start Guide.
  2. After final review and approval of the project completion documents, MassCEC will inform the lender to proceed with the final disbursement of the loan amount via a two-party check.

Reminder: Per the Mass Solar Loan Program Manual, the deadline to submit project completion documents is 1 year after the loan support application has been approved.
