What is Grid Connection?
The link between your solar panel system and the national electricity grid, allowing import and export of power.
Quick Answer
In Ireland, residential solar systems connect to the ESB Networks distribution grid. Systems up to 50kWp can connect under the microgeneration framework with a simple notification to ESB Networks (NC6 form). Your installer handles this paperwork. The process typically takes 2–4 weeks. Grid connection is free for domestic microgeneration systems.

Grid Connection Explained
Grid connection refers to the physical and regulatory link between a solar PV system and the national electricity grid. A grid-connected system allows you to draw electricity from the grid when solar output is insufficient and export surplus generation when output exceeds demand. Grid connection requires approval from the local distribution network operator, compliance with technical standards, and appropriate metering.
