As the world becomes more aware of the need to reduce carbon emissions and move towards sustainable energy sources, solar power is becoming an increasingly popular option in Ireland. With the government offering grants and incentives for homeowners to install PV panels, many are considering whether investing in solar panels is worth it.

In this article, we’ll take a comprehensive look at the benefits, output, cost savings, government grants available for solar PV panels in Ireland, and the planning permission required to install them.

What Are the Benefits of Solar Panels?

1) Cost Savings

One of the most attractive benefits of PV panels is the cost savings on electricity bills. By generating electricity from the sun, homeowners can significantly reduce their reliance on traditional energy sources such as coal or natural gas, leading to substantial savings on energy bills, especially during the summer months.

2) Environmentally Friendly

Solar energy is a clean and renewable power source, producing no emissions or pollution, making it an ideal option for those looking to reduce their carbon footprint.

3) Low Maintenance

PV panels are relatively low maintenance, requiring only a simple cleaning every six months and an annual check-up to ensure they are working at peak efficiency, making them a convenient and hassle-free option.

4) Increase in Home Value

Installing them can increase the value of your home as they are seen as a desirable feature that can lower energy costs and improve the home’s overall efficiency.

5) Independence

They allow you to generate your own power, which can be especially beneficial in remote areas or during power outages.

What output can I expect from solar panels in Ireland?

The output of solar panels in Ireland depends on various factors such as location, panel angle, and system size. On average, a medium-sized solar PV system in Ireland can generate approximately 4,000 units of electricity per year, enough to cover around 70% of the electricity usage for an average household.

Despite Ireland’s reputation for limited sunshine, the country’s climate favours photovoltaic (PV) solar more than many people realise, making them a smart investment for Irish homeowners. With surplus energy available to export to the grid on brighter days, a modern solar system can provide a decent output, helping homeowners reduce their carbon footprint and save on energy bills.

How much can I save with solar panels?

The cost savings from solar panels can vary depending on a number of factors, including the system’s size, the property’s location, and the amount of sunlight it receives. However, on average, a 4kW PV panel system can save a household around €600-€800 per year on energy bills.

Over 20 years, this can add up to a total savings of €12,000-€16,000, making the installation cost recoupable within a few years, with the rest of the savings being pure profit.

How much do solar panels cost in Ireland?

The cost of solar panels in Ireland can vary depending on the size of the system and the company you choose to install them. On average, a 4kW PV panel system can cost between €8,000 and €10,000.

However, it’s essential to keep in mind that this is just an estimate and the final cost may differ based on the specific needs of your property and any additional components that may be required. It’s always recommended to consult with our professional to get an accurate estimate for your specific needs.

Are there government grants available for solar panels in Ireland?

The Irish government offers a number of grants and incentives for homeowners to install PV panels. These include:

SEAI Grant

The Sustainable Energy Authority of Ireland (SEAI) grant provides €2,100 for a 4kW PV panel system. This grant can help offset the installation cost and make them more affordable for homeowners.


The Targeted Agricultural Modernisation Scheme II (TAMS II) grant can provide up to €9,300 or up to 60% of the overall cost of a PV panel system for farmers. This grant is specifically designed to support farmers in modernising their agricultural operations and becoming more sustainable.

These grants can significantly reduce the cost of installation and make solar PV panels more affordable for homeowners in Ireland.

Do I need planning permission for solar panels in Ireland?

In most cases, planning permission is not required for solar PV systems installed on residential roofs. However, it’s best to check with your local council to confirm if planning permission is needed for your specific property and location.

In the case of installing solar PV on the roof of a commercial or industrial building, planning permission is typically required for systems larger than 50 sq. m or representing more than 50% of the total roof area. This is because larger systems may have a greater impact on the surrounding area and may need to meet additional regulations and guidelines.

Make an Informed Decision: Investing in Solar Panels in Ireland

As we’ve seen, investing in solar PV panels can save you money on energy bills, decrease your carbon footprint, and increase your home value. With government grants available, the cost of installation can be significantly reduced.

How much can I save by installing solar panels in Ireland?

The exact savings depend on your energy usage and the size of your solar system. However, a typical home using a 5kW solar system can save approximately €900-€1,000 on energy bills annually.

Does Ireland have a good amount of sun for solar energy generation?

Despite its reputation for cloudy weather, Ireland receives enough sunlight to make solar energy viable. Modern solar panels can generate electricity even on overcast days.

What grants are available for solar panel installation in Ireland?

The Sustainable Energy Authority of Ireland (SEAI) provides grants for homeowners who install solar panels. You may receive significant financial assistance depending on the system size and other factors.

Can I offset my electricity bill with solar panels in Ireland entirely?

While it’s possible to significantly reduce your electricity bill with solar panels, completely offsetting your bill depends on factors like your energy usage, the size of your solar system, and the amount of sunlight your location receives.

Can you sell electricity back to the grid in Ireland?

Yes, it is possible to sell electricity back to the grid in Ireland through a process called "net metering" or "grid connection." Under this scheme, excess electricity generated by your solar panels can be fed back into the grid, and you may receive credits or payments for the energy exported.
