Net Metering

• You will not be paid for the electricity you generate.
• The capacity of the panels must be decided according to the monthly usage

For instance, if your monthly bill is around 200 KWh per month, installing a solar PV with a capacity of 2kW will be sufficient.  A system with a 2kW capacity costs around LKR 500,000.

If your monthly usage is less than 200 units, it will take a long time to recover your settlement.

If you happen to generate more than what you consumed, extra units will be banked for a period of 10 years in between you can consume at occasions where you consumed over what you generated.
