Net metering is a billing mechanism enabling owners of solar energy systems to receive credits or compensation for surplus electricity they produce and feed back into the grid. It serves to regulate the interaction between solar panels and the grid. Under net metering, the solar energy system is linked to the electric grid, allowing any excess electricity generated by the system, beyond the owner’s immediate consumption needs, to be exported to the grid. Owners receive credits or compensation for this surplus electricity, which can offset their electricity bills. Connecting your solar system to the grid is mandatory under the solar subsidy scheme in Kerala.

Credits or compensation are typically calculated by assessing the disparity between the amount of electricity generated and the amount consumed by the owner during a specific period, such as a month. Should the solar energy system produce more electricity than consumed, the surplus energy is transferred to the grid. Conversely, if the system generates less than the home’s consumption, the owner covers the difference at the retail rate.
