What is an On-Grid Solar System?
An on-grid solar system (also known as grid-tied solar) is a solar power setup that is connected directly to the national electricity grid (CEB/LECO). Unlike off-grid systems, it does not require a battery backup and is designed to:
- Generate electricity from solar panels during daylight hours
- Use solar power directly for household or business consumption
- Feed excess energy back into the grid (through net metering or net accounting)
- Draw power from the grid when needed (e.g., at night or cloudy days)
Why Choose On-Grid Solar? It’s the most cost-effective solar solution for Sri Lanka since it reduces electricity bills without the added cost of battery storage.
