Battery storage for homes and small businesses in Dublin and Leinster

Solar battery storage in Dublin that helps you use more of your own power

A home battery stores surplus solar generation from the day and releases it in the evening, when many households cook, heat water, and charge devices. SunHarvest designs and installs solar battery storage in Dublin, with a practical focus on safety, clear sizing, and reliable monitoring. We are based on Alfie Byrne Rd in Dublin 3, close to Clontarf, and we prioritise the Greater Dublin Area.

Higher self-consumption

Use more of your PV on site and reduce evening imports when rates are often higher.

Safety first

We plan location, clearances, protection devices, and commissioning checks with care.

Monitoring included

Clear visibility of generation, battery charge, and import and export in one app.

Is a battery right for your home?

Battery value depends on how much surplus solar you have during the day and how much electricity you use in the evening. We can review your usage pattern and roof output estimates to recommend a sensible size.

Best fit when day time generation exceeds day time use.
Useful for families with higher evening demand and EV charging schedules.
Can reduce grid imports while keeping monitoring simple.

What solar battery storage does for a Dublin household

Solar panels produce most of their electricity in the middle of the day. Many homes in Dublin, including Dublin 3 and Clontarf, use less power at those hours because people are at work or school. Without a battery, surplus generation is typically exported to the grid. Export can be valuable, but a battery gives you another option: store that surplus and use it later, often during the early evening when cooking, laundry, showers, and device charging increase demand.

The aim of battery storage is not to promise a specific bill reduction for every home. It is to increase the share of your solar PV that you use on site. That can reduce imports, smooth your daily demand, and give you more control over when you buy electricity. For some households, a modest battery improves comfort because it covers regular evening loads. For others, especially where the home already uses a lot of power during the day, the best value may come from focusing on the PV system size first.

We approach battery storage as part of a whole system: PV output estimates for your roof, usage patterns, and how your inverter and distribution board will be configured. We have been installing solar PV systems for over eight years, and our process prioritises safe cable routes, clear labelling, and a handover that helps you understand the system rather than simply leaving an app link.

Battery storage outcomes we focus on

Reduced evening imports

Shift mid day surplus to the hours when many households draw the most power.

Higher self-consumption

More of your PV generation is used at home rather than exported by default.

Reliable commissioning

We validate charging and discharge behaviour, monitoring data, and protection settings.

SEAI grant note

The SEAI Solar Electricity Grant in 2026 supports solar PV and remains up to €1,800. Battery choices are usually made as part of the overall system design and budget plan.

Monitoring that is easy to understand

We set up the monitoring so you can see solar generation, battery charge, and import and export. During handover, we explain what to expect on bright and overcast days and how seasonal changes affect output.

How we size a home battery (without guesswork)

Battery sizing should be driven by data you can verify: typical daily usage, the portion of usage that happens after solar production drops, and the expected surplus from your PV system. Oversizing can tie up budget in capacity you rarely use, while undersizing can mean the battery fills early and you still export a large share of generation. Our approach is to choose a size that fits your household’s normal rhythm, then confirm the expected behaviour in writing before installation.

Get a sizing recommendation

Step 1: usage and tariff review

We review your typical usage patterns and, where possible, a recent bill or smart meter view. The key is when you use electricity, not just the total. Evening demand is the most important driver for battery value.

Step 2: PV output estimate for your roof

Roof orientation and shading in Dublin can vary street by street. We check roof planes, nearby trees, and chimneys, then estimate how much surplus you are likely to have at mid day through the year.

Step 3: equipment and placement plan

We confirm battery location, ventilation, access, and clear cable routing. We also choose a compatible inverter approach: hybrid for new builds or a retrofit plan where appropriate.

Battery placement and safety considerations

A battery system is electrical equipment and needs an installation plan that considers access, clearances, and protection. In Dublin homes, the most common locations include utility rooms, garages, and other suitable internal spaces. We assess the wall strength and mounting position, keep cable runs neat and labelled, and confirm that shutoff points are accessible. We also verify commissioning behaviour and show you how to read key numbers in the monitoring app.

Safety also includes understanding how the system behaves during outages. Not every battery provides backup power by default. If backup is important to you, we discuss the required hardware and what circuits you would want to support. If you do not need backup, we keep the system simpler and focus on daily energy shifting.

Solar battery storage FAQ

If you are comparing solar battery storage in Ireland, focus on whether the battery helps your day to day usage pattern, how it will be installed, and how you will monitor performance. These answers cover the questions we hear most often from Dublin homeowners.

Do I need solar panels before I add a battery?

A battery is most effective when paired with solar PV, because it stores surplus generation from the day. Some homes add a battery as part of a new solar installation, while others retrofit later. We can assess the best approach during a site survey in Dublin.

How do you decide what size battery to install?

We size around your evening usage and your expected day time surplus. The goal is a battery that regularly charges and discharges in a useful range, rather than a large capacity that stays half used for most of the year.

Will a battery provide backup power during outages?

Not always. Backup capability depends on the inverter setup and additional components. If you want backup for key circuits, we will explain what is required and what circuits are practical to support in your home.

Is battery storage worth it in Dublin’s climate?

Dublin’s coastal climate still provides useful annual solar generation, and the value of a battery comes mainly from shifting surplus to evening usage. We look at your roof and your day to day demand to judge whether a battery improves your plan.

Does the SEAI grant cover batteries?

The SEAI Solar Electricity Grant in 2026 supports solar PV and remains up to €1,800, based on installed kWp. Battery choice is typically part of the overall system budget and design discussion.

Which areas do you cover for battery installs?

We are based on Alfie Byrne Rd in Dublin 3 and prioritise Dublin and the Greater Dublin Area. We also work across Leinster, including Wicklow, Meath, Kildare, and Louth.
