Cost and Performance

The cost of buying a solar electric system can vary based on system size, location, equipment used and other factors. Though MassCEC cannot say what a "good" price is for your solar electric system, we can help you see what others are paying for solar projects around the Commonwealth.

MassCEC and the Department of Energy Resources have gathered information on solar systems installed in Massachusetts under various state programs, such as the Solar Carve Out.  Residents interested in solar can use the below dashboard to explore this information, better understand the economics of installing solar on their homes, and compare solar system information across the Commonwealth. The prices below are median values, which may not reflect unique project parameters. Note pricing can vary based on project-specific factors like site condition or chosen equipment. MassCEC recommends comparing at least three isntaller quotes to help customers determine their best option.

This dashboard is based on the data included in our Solar PV Systems in MA Report, which can be downloaded here in an excel format. Data about the performance of solar electric systems in Massachusetts can also be downloaded as part of the SREC Capacity Factor Report.
