4. Introduction
Solar energy is a clean, pollution free and renewable source of energy.
Karnataka state is blessed with about 240 to 300 sunny days with good solar radiation
The solar policy 2014-2021 announced by the Government of Karnataka emphasis on solar
rooftop projects and with facilitation from Karnataka Electricity Regulatory Commission
(KERC) MESCOM has taken the lead to implement net-metering for rooftop projects.
MESCOM has proposed to implement the project for all consumers in MESCOM circle.

5. FAQs on rooftop solar PV
What are the main components of a solar PV system?
Solar Modules: Convert the solar light to electricity.
Inverter: Convert the Direct Current (DC) from
modules to Alternating Current (AC).
The output from the inverter is connected to the
the distribution board.

6. What is rooftop solar with net metering?
When your electricity demand (load)
exceeds your solar generation, energy will
be imported from the MESCOM supply.
When your solar generation exceeds your
load demand (consumption), the energy will
be exported to the MESCOM grid.

8. What are the benefits of rooftop with net metering?
Net metering policies are intended to promote distributed generation where consumers
with availability of roof space can generate energy and sell to the utility.
Net meters (Import-Export) meters will be installed which will account the export and
import of energy.
Load demand of consumers will vary daily and with net metering you will have the
benefit of ‘selling’ the solar energy you generate when your consumption is low.
MESCOM will pay the consumer if the net export exceeds the import for a month
As per KERC order (10th Oct 2013) the tariff are as follows(until further order revision)
KERC approved tariff
Without MNRE subsidy INR 9.56/kWh
With MNRE subsidy INR 7.20/kWh

Timelines
Application approval 7 working days from application
submission
Approval for installation 3 working days from the date of
submission of technical details
Installation 180 days
Approval from Chief Electrical Inspectorate 7 working days after submission of
work completion certificate
Approval for grid synchronisation 3 working days from CEI inspection

14. Billing and payment
The consumer shall receive a monthly net import/export bill indicating either net export to the
grid or net import from the grid.
“Import”- means energy supplied by the MESCOM grid.
“Export”- means energy delivered to the MESCOM grid.
In case of net import bill, the consumer shall pay the same as per existing tariff.
In case, the export energy is more than the import, AEE, C,O&M sub-division will arrange for
the energy exported as per the KERC approved tariff through NEFT.
The amount payable by the MESCOM to the Seller for energy injected to the MESCOM grid
(excluding self-consumption) during the billing period becomes due for payment, which shall
be settled within 30 days from the date of meter reading and credited to the bank account
through NEFT.

15. Documentation
