Massachusetts has had very popular programs to support commercial solar. The incentives reward solar generators by an added incentive for the solar added to the grid, beyond simply compensating for the rate of electricity. 

Under the SMART program, you receive a check from the utility based on a fixed dollar number paid per kilowatt-hour of solar generated, multiplied by your actual solar generation EVERY month for your business for 20 years! In many situations, putting solar on your business will generate more in savings and SMART credit payments than the owners pay out each month for the loans on their solar generation systems. You can truly be cash flow positive from day one-saving the world while saving money.
