The system is interfaced with the power utility grid. Here, Solar PV system takes the first priority to run the loads. The excess power, if generated will be exported to the power grid. In case of deficit of solar power, the differential power is drawn from the power grid. In this system, a bi-directional meter is installed to measure the net energy (Net metering).
BESCOM or the power utility company in Bangalore (India) is currently paying 9.56 rupees for every unit of energy that is exported to the grid (On net metering basis)
