The cost of buying a solar electric system can vary based on system size, location, equipment used and other factors.

Residents interested in solar can use the below dashboard to explore the cost and performance of solar PV systems installed across Massachusetts installed under various state programs (such as SMART and Solar Carve Out). Prices listed below are shown as median values, which may not reflect unique project parameters. Pricing may vary based on project-specific factors, such as site condition or chosen equipment. MassCEC recommends comparing at least three installer quotes to help customers determine their best option.

This dashboard is based on the data included in our Solar PV Systems in MA Report (Excel format). Data about the performance of solar electric systems in Massachusetts can also be downloaded as part of the SREC Capacity Factor Report. (Note: This 54 MB Excel file may be slow to download). The 11-year average net capacity factor for solar PV systems in Massachusetts is 13.05 percent (2010 to 2020).
