Financial Incentives for Solar PV and Batteries

There are a number of federal and state financial incentives for making green energy investments. Incentives for PV and batteries include the following:

Financial Incentives for Solar Photovoltaics (PV)

The Solar Massachusetts Renewable Target (SMART) Program

The Solar Massachusetts Renewable Target (SMART) Program is a production-based incentive paid directly to solar electric system owners based on the amount of electricity produced.

Once a system is approved to participate in the program, a typical residential system will be eligible to receive incentive payments for 10 years. Incentives are issued by utilities monthly via check or electronic payment.

Customers are eligible for a base incentive rate and other adders such energy storage adders.

SMART Program additional details and special requirements

Net Metering

Net Metering allows solar electric system owners to sell any excess power they produce back to their utility and receive a credit on their electric bill valued at almost the full retail rate for the power produced. A net meter spins backwards as a solar electric system produces energy, just as it spins forwards when the customer consumes electricity. The customer is then billed for the net electricity consumed or receives a credit for net electricity produced. Credits received can be applied towards future electricity bills.

Net Metering additional details and special requirements

System sizes under 10kW are exempt from the net metering cap and receive near full retail value for their electricity.

System sizes over 10kW may be subject to the net metering cap and receive value at 60% of the retail rate.
