possible tax on SMART program payments

Hi there,

Owners of solar panels can participate in various programs to sell electricity back to the grid. For example, the SMART program in New England. If this income taxable?  Several electricity providers (for example, National Grid) send 1099-MISC forms to the participants of this program.  If it is taxable, should it be then offset against the cost of solar panels/batteries? It would make sense because this "income" is generated by the purchased means, the solar panels, and equipment. So the expenses to buy and install it should counterbalance the "income".

I would greatly appreciate clarification on this new topic.

Thank you.
