Are Solar Panels Worth It in Ireland?
The benefits of solar panels are numerous, including reducing your annual electricity bill, offering the opportunity to offset energy costs by selling any excess energy produced back into the national grid, and reducing Ireland's overall greenhouse emissions. The SEAI offers grants of up to €1,800 for PV solar installation in 2025.
Are Solar Panels Worth It in Ireland?
The short answer is yes, solar panels are worth it in Ireland for most homeowners, offering significant long-term financial and environmental benefits. When factoring in generous SEAI grants and rising energy costs, the investment is proving increasingly valuable.
Solar panels as a technology have a tremendous amount of benefits in Ireland. Not only are they a great solution to the climate crisis, they can also provide a number of financial and practical benefits to help reduce your carbon footprint and costs at home.
Here are some of the main solar panel benefits:
- Greener Energy
Solar panels use sunlight to generate electricity rather than burning fossil fuels. Since there’s nothing else involved in producing the energy, solar panels emit no greenhouse gases and because we’ll never run out of sunlight, it is a completely renewable energy source and better for the environment. - Cheaper Bills
Solar energy can also help you make savings on your energy bills. Since you’ll be using the power from the sunlight, you’ll be using less energy from your energy provider, making your monthly bills much cheaper. After investing in solar panels, you’ll get your return on your investment in as little as three to four years. - Independence from the Grid
With solar panels, you don’t use the energy from the mainstream grid to power your home. This means you don’t have to worry about power cuts or problems with your grid connection to have energy at home. Especially if you invest in a solar panel battery, you’ll have a full back-up power ready to go whenever you need it.
How Much Can I Save With Solar Panels in Ireland?
The average home with 4 solar panels installed can save over €500 per year on their electricity bills.
There are several factors that will influence how much money you can save with solar panels, including:
- Number of panels installed.
- Your home's annual consumption.
- Positioning of your panels.
- Number of sunny days per year.
The website Purevolt.ie uses a solar panel savings calculator to estimate the potential savings your solar panel system could have. We used it to estimate the savings a standard home with 4 panels installed could make in a year.
- ⛅ Estimated Annual Savings with 4 PV Solar Panels
- Rooftop space required - 3.3m x 3.7m
- System size - 1.74 kWp
- Annual units generated - 1539 kWh
- Annual CO2 emissions saved - 531 kgs
- Annual bill savings - €527.41
Calculations based on standard values and a unit rate of **€0.42** per kWh. Figures are designed to give an estimate and are for illustrative purposes.
How Much Do Solar Panels Cost in Ireland?
A key part of deciding if solar panels are worth it is understanding the upfront financial commitment and how quickly you can expect to recoup that investment.
The total cost of a solar PV system in Ireland depends heavily on the system size (measured in kilowatt-peak, or kWp) and whether you choose to install a battery for energy storage.
Average Solar PV System Cost (Before Grant)
For the typical Irish homeowner, a standard solar PV system designed to cover most daily electricity needs costs:
| System Size (kWp) | Typical Panels | Estimated Cost (Supply & Install) |
|---|---|---|
| 3 kWp | 6 - 8 panels | €6,000 - €8,000 |
| 4 kWp | 8 - 12 panels | €7,500 - €10,000 |
| 6 kWp | 12 - 16 panels | €9,500 - €13,000+ |
Note: These figures are estimates and can vary significantly based on your chosen installer and the quality of components.
Factors Affecting Your Final Price
- System Size (kWp):The largest cost driver is the number of panels you install. Most Irish homes achieve the maximum savings from a 4kWp system, which also qualifies for the maximum SEAI grant.
- Solar Battery Storage: Including a battery (e.g., 5kWh to 10kWh) can add an extra €2,000 to €5,000 to the initial price, but it dramatically increases your self-consumption, meaning less reliance on grid electricity.
- Roof Complexity: Difficult roof access, multiple roof planes, or materials like slate may increase labour costs.
- Optimisers/Micro-inverters: If your roof has significant shading (e.g., from a chimney or tree), optimisers may be necessary to maximise output, which adds to the per-panel cost.
Payback Period
Combining the annual savings, the SEAI grant (up to €1,800), and the income from selling surplus energy (Clean Export Guarantee), the typical payback period for a residential solar PV system in Ireland is often quoted between 4 and 7 years.
Are There SEAI Grants for Solar Panels in Ireland?
As part of the government's climate action plan, grants for solar panel installation are available from the Sustainable Energy Authority in Ireland (SEAI).
The amount that you receive for the solar panel grant depends on a lot of factors. However, the most important is the peak output of your new solar panel system.
This means that the amount of power that your solar panel generates at peak times will determine how much you’ll receive in the grant:
| Kilowatt Peak (kWp) | Grant Amount |
|---|---|
| 1 kWp | €700 |
| 2 kWp | €1,400 |
| 3 kWp | €1,600 |
| 4 kWp | €1,800 |

The solar panel grant will cover both the labour and the material for the solar panels to be installed in your property.
For many of the grants, the maximum amount is €1,800, which is lower than the average price for PV solar panels (around €4,000) so the grant is intended to foot part of the bill for the over costs.
The grant doesn't cover any solar panel repairs or the purchase of a solar panel battery.
Grant Amount Capped 2025
In 2025, the grant is capped at €1,800. The Government plans to reduce the grant by up to €300 every year, as it expects the cost of solar panel systems to reduce over time. It is intended that the grant will end in 2029.
Do Solar Panels Produce a Lot of Energy in Ireland?
On a sunny day, a typical solar panel system can generate up to 4.5 kWh of electricity per day during the year.
This can reach up to around 10–15 kWh in the summer! This is enough to power a typical household for a day. Given that the average home uses 4,200 kWh a year of electricity, a solar panel system can put a dent in your bill!
Since solar panels are becoming increasingly popular in Ireland as a way to generate renewable energy. The Irish government has set a target of 80% of energy coming from renewable sources by 2030.
Selectra's Solar Panel Tip
"If you think the Irish climate is not suitable for solar panels, even on a cloudy day, PV solar panels can still generate electricity as they capture energy from sunlight, not the heat from the sun"
Is My Home Suitable for Solar Panels?
Before committing to the cost, it's essential to check if your home meets the basic requirements for efficient solar panel generation.
Key Installation Requirements
- Orientation (Aspect): The ideal orientation is a South-facing roof, as this captures the most direct sunlight throughout the day. However, East- and West-facing roofs are also highly viable and can generate excellent results. East-West splits are popular for maximising self-consumption, as they generate power in the morning and evening, coinciding with typical household usage.
- Shading: This is perhaps the most critical factor. Minimising shading from chimneys, mature trees, or neighbouring buildings is essential, as even shading on one part of a panel array can drastically reduce the output of the entire system.
- Roof Condition and Size: Your roof must be in good repair to support the weight and lifespan of the panels (typically 20-25 years). You will need sufficient available roof space. For a typical 4kWp system, you will need approximately 17-20 square metres of clear roof area.
SEAI Eligibility Check
To qualify for the valuable SEAI Solar PV Grant, your home must meet a few specific criteria:
- The dwelling must be an existing home, built and occupied before December 31st, 2020.
- The system must be installed by an SEAI-registered installer.
- The work must be completed by a Safe Electric Ireland electrician.
Planning Permission: In Ireland, domestic solar panel installation is typically exempt from planning permission, provided your home is not a protected structure or in an Architectural Conservation Area (ACA).
Can I Sell Energy Produced by Solar Panels?
Microgeneration has become more and more popular, as homeowners who produce a certain amount of their electricity from small scale renewable sources can now sell excess energy back to their supplier.
Once you have solar panels installed, you can apply for the government's Micro-Generation Support Scheme and begin selling any excess energy you produce back to your energy supplier.
Suppliers now offer a 'feed in' tariff, whereby you are paid a certain rate for every kWh you sell back to the supplier.
| Supplier | Rate per kWh | Payment Method |
|---|---|---|
| Bord Gáis | 18.5c | Twice yearly credit |
| Electric Ireland | 21.0c | Credit as per billing cycle |
| Energia | 24.0c | Credit as per billing cycle |
| Flogas | 20.0c | Bi-monthly credit |
| Pinergy | 25.0c | Monthly credit |
| SSE Airtricity | 24.0c | Twice yearly credit |
| Yuno | 15.89c | Twice yearly credit |

Maximising Your Earnings: Competitive Export Tariffs
The financial case for solar is significantly boosted by the Clean Export Guarantee (CEG), which is the mechanism that ensures you get paid for every unit of surplus electricity you export back to the grid.
Focus on the Export Rate
Do not assume your current electricity supplier offers the best deal for your exported energy. The CEG rate varies significantly between energy providers and is often competitive.
Choosing the provider with the highest rate can dramatically reduce your payback period.
Best Residential CEG Rates:
| Energy Supplier | Clean Export Guarantee (CEG) Rate | Notes |
|---|---|---|
| Pinergy | 25.0c per kWh | Currently the highest standard, publicly available rate. |
| SSE Airtricity | 32.0c per kWh (Premium) | Only available to customers who have their solar system installed by a specific partner (Activ8). |
| Electric Ireland | 19.5c per kWh | A highly competitive and stable standard rate. |
| Energia | 18.5c per kWh | Competitive industry standard. |
Tax Exemption on Export Income
Crucially, the first €400 earned annually from micro-generation income is currently exempt from Income Tax, USC, and PRSI until the end of 2025. This further increases the net financial return on your investment.
