Net metering is an agreement that allows the solar PV system owner to sell excess solar energy to the utility company or buy deficit energy from the utility company using a meter to track this energy exchange.

Genus being the largest manufacturer of electricity meters, offers the grid-tied rooftop systems with net meters. The loads can run on solar power as long as there is sufficient energy available from the sun during the day. Any deficit is taken care by the main utility supply. However, if the solar energy production is in excess as compared to the load requirement at that moment, the excess energy can be either stored in the batteries (if available) or can be transferred back to the utility grid. This difference of energy is tracked and maintained in Genus Net Meter.
