Net metering in rooftop solar projects


 

Net metering allows electricity meter to spin forward when electricity flows from the grid into your building, and backward when your system produces surplus electricity that is not immediately used. Your excess electricity is “banked” on the utility grid. Metering helps to measure the solar gross generation, consumer load consumption, export and import to and from the Grid apart from measurement of AC system voltages and currents, frequency etc. As per the guidelines of CERC, the metering arrangement requires to accommodate DG sets and/or battery inverter etc. as per the need of solar developer without affecting the sealing and security of complete metering system apart from cabling and switchgear from solar panel to solar meter.
