On-Grid Connection Schemes (Sri Lanka)

1. Net Metering Scheme

You use solar power directly, and any excess sent to the grid is credited to your bill. You pay only for the net usage, with no cash payment for surplus energy.

Main Benefit: Save by reducing your CEB bill through energy credits

2. Net Accounting Scheme

You can offset your usage and earn money, as CEB/LECO pays for any excess electricity you send to the grid.

Main Benefit: Earn income for every exported unit

3. Net Plus Scheme

you sell all your solar power to the grid and pay separately for your own use, with separate meters for import and export.

Main Benefit: Fixed income from total solar generation

4. Net Plus Plus (Net ++) Scheme

You sell all solar power to the grid and pay separately for your use. This advanced scheme lets your system generate beyond contract demand, acting as a mini power plant.


Main Benefit: Maximize income from unused roof space
