Massachusetts Net Metering Laws & Utility Buyback Explained

During bright summer days, your system will likely generate more power than your home can consume. This excess electricity flows backwards through your meter into the grid. Your utility company is required by law to credit you for this power at the 1:1 retail rate (for residential systems under 10kW, which are exempt from state net metering caps). You bank these credits during the summer and use them to offset your energy consumption during the shorter winter days.

Net metering handles your month-to-month utility bill reduction, while the SMART program runs concurrently to issue you direct performance payments. Together, these two mechanisms ensure your roof becomes a highly profitable financial asset.
