For a solar installation, we will change the electric meter to a “net meter.” This meter measures electricity flowing in two directions to determine your “net” usage, which is the difference between the amount of power you supply into the energy grid and the amount you get from it. The reading on a net meter runs backwards when you are supplying energy into the grid. If there’s a billing period during which you supplied more power than you used, you’ll earn credits that will reduce future bills.

Compiled from public records, 2026. Tariffs and interconnection rules change; verify with PSE&G Long Island before you rely on this. The useful move: if an installer says you need a main panel upgrade, ask how these tap and interconnection policies were considered first.
