Battery Storage

Stop Giving Your Solar Energy Away.
Store It. Use It Tonight.

Without a battery, unused daytime solar goes to the grid for a few cent. With one, you use your own clean electricity morning, noon, and night — and cut your grid bill by up to 90%.

The Impact

What a Battery Actually Does for You

The difference between solar with and without a battery is significant — especially in Ireland where most consumption is in the evenings.

How It Works

Your solar system, working around the clock

1

Morning — Panels generate

From sunrise, your panels start producing electricity. Your home uses what it needs directly from the panels — for free.

2

Daytime — Battery charges

Any excess electricity (what you're not using) flows into the battery instead of being wasted on the grid at a low export rate.

3

Evening — Battery powers your home

When the sun goes down and your family gets home, the battery kicks in. Lights, TV, cooking, EV charging — all from stored solar energy.

4

Night — Grid as backup only

The grid is your backup, not your supplier. Only when the battery runs low does any grid electricity come in — at night-rate prices.

REPLACE: Battery + inverter installed together on wall — neat wiring, clean setup
Government Grant

€600 SEAI Grant for Battery Storage

Battery storage qualifies for its own SEAI grant — on top of the panel grant. We apply for both simultaneously.

€600

Battery Storage SEAI Grant 2025

Available to all qualifying homeowners installing battery storage alongside solar PV. Combined with the €1,800 panel grant, you can receive up to €2,400 in total government support. We handle all the paperwork — you just book the install.

Questions

Battery Storage — Common Questions

Can I add a battery to my existing solar panels?
Yes — in most cases we can retrofit a battery to an existing solar installation using AC coupling. We assess your current inverter during a free survey and recommend the best solution. You may also be eligible for the €600 SEAI battery grant if you haven't previously claimed it.
What size battery do I need?
For most Irish homes, a 5–10 kWh battery covers evening demand comfortably. If you have an EV or high evening usage, 10–15 kWh makes more sense. We calculate the right size based on your actual electricity consumption patterns during your free home survey — not a generic estimate.
Does a battery work during a power cut?
The Tesla Powerwall includes backup power as a standard feature — it automatically switches to island mode during a grid outage and keeps your home powered. The Huawei LUNA and GivEnergy systems can also provide backup power but require specific configuration. We confirm backup capability during your survey.
How long does a battery last?
All batteries we install carry a 10-year warranty guaranteeing at least 70% of original capacity. In practice, batteries typically last 12–15 years before significant degradation. Replacement at that point is straightforward — the rest of your system continues working.
