Solar Net Metering

 

When a customer installs a grid connected PV systems at any premise served by either the Ceylon Electricity Board (CEB) or Lanka Electricity Company (Private) Limited (LECO), your electricity meter will be replaced with a two-way meter. The meter will have two registers; the “import” register and the “export” register. You can produce electricity (using the PV array) and first use that electricity for your own requirements and send the surplus back to the grid.

Such “exported” electricity units will be registered in the “export” register of your meter. During certain times of the day, your own electricity production may not be adequate for your requirements. Then your consumption will be recorded in the “import” register. When the electricity meter is read once a month, you will pay only for the difference between the “import” and the "export". If in any month you have exported more than what you imported, your bill will only carry the monthly fixed charge (no charge for the units of electricity), and the excess exported units will be credited to your next month’s bill.
