Grid connectivity of Solar RoofTop-PV systems on Net metering in BESCOM
The Government of Karnataka has announced the Solar policy 2014-21, grid connected solar rooftop system under net-metering basis forms an integral part of the policy.
In grid-connected solar PV systems, the DC solar energy produced by the solar panels is converted to AC (alternating current) by a solar grid inverter. The output of the solar grid inverter connected to the distribution switch board of the building through bi-directional meter. Generated energy from the SRTPV system is first consumed (self-consumption) by the loads of the building (lights, fans, appliances, etc.). If the SRTPV generated energy is more than the building loads consume, the surplus energy will automatically be exported to the BESCOM distribution network (the grid). If there is less solar energy generated than the loads of the building requirement, the shortfall energy will be drawn from the grid (energy import).
Tariff from BESCOM:
The tariff for injecting surplus energy by rooftop installation will be as per the prevailing tariff determined by KERC from time to time. (At present the tariff is Rs.9.56 per unit for installations without subsidy and Rs.7.20 per unit for installations with subsidy up to 31st March 2018).
Billing and Payment:
BESCOM will issue monthly electricity bill for the net metered energy on the scheduled date of meter reading.
