What is the difference between "Feed-in-tariff" and "Net metering"?

The feed-in tariff (FiT) and net metering are both methods by which a utility company compensates a homeowner or other producer for the energy fed back into the grid. Simply put, net metering requires one meter, FiT requires two.

In net metering the meter simply “runs backwards” when a homeowner’s solar panels are producing more electricity than the property is using, sending the excess energy back through transmission lines to other energy consumers. In contrast, implementing FiT requires two meters, one to measure consumption, the other to measure generation, which generally commands a higher price than the grid energy
