Solar Guide

Battery & Grid

Learn about battery storage, backup power during outages, and how solar works with the electricity grid.

What is net metering?
Net metering (or micro-generation export) lets you send excess solar energy back to the grid in exchange for bill credits, effectively using the grid as a 'battery.' In Ireland, the Clean Export Guarantee allows you to earn for every kWh you export.
What happens during a power outage?
Without a battery, grid-tied systems shut off for safety. With a battery backup, you can keep essential circuits running — lights, fridge, internet, and more — until the grid comes back online.
