Battery Storage Systems

Battery Storage — Use Your Solar Power Day and Night

Without a battery, excess solar energy generated during the day is exported to the grid. With a battery, you store it and use it in the evening when electricity is most expensive. A battery can increase your solar self-consumption from around 40% to over 80%.

How It Works

1. Daytime — your solar panels generate electricity. What you don’t use immediately charges the battery.
2. Evening — when the sun goes down, the battery supplies your home instead of the grid.
3. Night — if the battery runs low, you switch back to grid electricity as normal.
4. Smart management — the system learns your usage patterns and optimises charging automatically.

Is a Battery Worth It?

For most homeowners with solar panels, adding a battery makes financial sense. The SEAI grant covers battery storage as part of the overall solar PV grant, and the increased self-consumption means you buy less from the grid.

The economics improve further if you’re on a time-of-use tariff, as you can avoid importing expensive peak-rate electricity.

Battery Options

We install leading battery brands including:

• 5.12kWh systems — ideal for most 3-4 bed homes
• 10.24kWh systems — for larger homes or higher consumption
• Modular systems — expand capacity later as needed

All our batteries come with a 10-year manufacturer warranty and are integrated with smart monitoring.
