How solar billing works in Sri Lanka
Exported energy spins your meter back, offsetting what you draw later.
In Sri Lanka, rooftop solar is often compensated through an arrangement that resembles net metering, where the electricity you send to the grid is typically credited against the electricity you draw from it. In many areas only the net difference at the end of a billing period is charged, so surplus generation in sunny months may help cover quieter ones. The exact crediting rules, billing windows, and any caps vary by region and utility and should be confirmed locally.
