Are solar panels worth it in Ireland?

Do they really offer value for money in our climate?
And can solar PV genuinely reduce electricity bills long term?

These are some of the most common questions we hear — and the short, honest answer is yes, solar panels absolutely work in Ireland.

Solar PV is now one of the fastest-growing renewable energy technologies in the country. In 2025, over 34,000 Irish homes had already installed solar panels, driven by rising electricity prices, improved consumer awareness, and strong government grant support.

Despite the myth that Ireland is “too cloudy”, solar panels generate electricity from daylight, not just direct sunshine. Even on overcast days, modern solar PV systems continue to produce clean, free power — making solar a reliable option for Irish homes, farms, and businesses.

Why More Irish Homes Are Switching to Solar PV

Several factors are accelerating the adoption of solar panels in Ireland:

• High electricity prices compared to the European average
• SEAI solar panel grants reducing upfront costs
• Improved solar panel efficiency and lower equipment costs
• A growing desire for energy independence and cost certainty

As of February 2026, solar PV grants remain available for homeowners, farmers, and businesses across Ireland, making now an ideal time to invest.

How Much Do Solar Panels Cost in Ireland?

The cost of solar panels in Ireland depends on system size, equipment quality, and optional extras such as battery storage or EV chargers.

• Typical system prices start from €5,400
• Homeowners can save up to €1,800 with the SEAI Solar Electricity Grant
• Average payback period: 5–7 years
• Some homes achieve payback in as little as 4 years

With some of the highest energy costs in Europe, many Irish households save thousands of euro over the lifetime of their solar PV system.

At Alternative Energy, we assess your property, roof space, and electricity usage to design the most efficient system possible. Every quote includes a free site survey, ensuring your system is correctly sized from day one.

Buying solar panels is similar to buying a car or computer — a basic system will work well, but if you’re considering battery storage, EV charging, or smart monitoring, it’s worth comparing brands and specifications carefully.

Do Solar Panels Work in Ireland’s Climate?

Yes — solar panels work extremely well in Ireland.

While we don’t get constant sunshine, Ireland receives plenty of daylight hours throughout the year, especially between March and October. Modern solar PV panels are designed to generate electricity even when sunlight is diffused through cloud cover.

Our cooler temperatures can actually improve panel efficiency, meaning Ireland’s climate is well-suited to solar generation.

How Are Solar Panels Installed in Ireland?

If you’re new to solar PV, we recommend starting with our free Homeowner’s Guide to Solar PV, which explains how systems work and what to look for when choosing an installer. 

Choosing an SEAI-accredited installer is essential if you want grant support and peace of mind and multiple quotes is always recommended.

Our Installation Process
As a fully SEAI-accredited solar PV installer, Alternative Energy carries out a detailed site survey before installation to:
• Assess your roof structure and electrical setup
• Design the most efficient panel layout
• Confirm inverter, battery, and equipment locations
• Provide a clear and transparent quote

Most solar panel installations in Ireland take place over two non-consecutive days:
Day One:
• Installation of engineered roof mounting system
• Solar panel fitting
Day Two:
• Electrical installation
• Inverter and battery setup
• System testing and commissioning

We also install battery storage systems, EV chargers, and hot water diverters where required.

You’ll be shown how to use your monitoring app so you can track solar generation and electricity usage in real time.

In most cases, your mains power only needs to be switched off for around 30 minutes.

How Do You Make Money From Solar Panels in Ireland?

Solar panels generate electricity that you can use directly in your home, farm, or business. The more solar power you use yourself, the greater your financial return.

Your savings usually depend on self-consumption:
• If you’re home during the day, solar power is used instantly
• Excess electricity can be exported to the grid for payment
• Battery storage allows you to store daytime energy for evening use

Beyond direct savings, solar panels provide protection from future electricity price increases, giving you long-term cost certainty and more disposable income.

Without solar panels, households rent electricity indefinitely from large suppliers. With solar PV, there’s an end point — after which much of your energy is effectively free.

Solar Panel Grants in Ireland (2026)

Several solar panel grants are available in Ireland to reduce installation costs:
Homeowners
• SEAI Solar Electricity Grant
• Save up to €1,800

Businesses
Non-Domestic Microgen Grant
• Save up to €162,600

Farms
TAMS 3 Solar Capital Investment Scheme
• Grant aid up to 60% (max €90,000)
Farmers may also be eligible for the SEAI Non-Domestic Microgen Grant.

Additional schemes may launch throughout the year. We expect the Sports Capital Grant to open in early 2026, supporting sports clubs and community organisations. Updates are shared on our website and social channels.

As an SEAI-approved installer, we handle grant-funded installations and support customers throughout the application process.

Frequently Asked Questions About Solar Panels in Ireland

Are solar panels worth it in Ireland in 2026?
Yes. With high electricity prices, SEAI grants, and improving technology, solar panels remain a strong investment for most Irish homes and businesses.

How long do solar panels last?
Most solar panels last 25–30 years, with performance warranties typically guaranteeing 80–85% output after 25 years.

Can solar panels power my home in winter?
Solar panels generate less electricity in winter due to shorter days, but they still contribute meaningfully. Many homes combine solar with battery storage to maximise usage year-round.

Do I need planning permission for solar panels in Ireland?
In most cases, planning permission is not required for rooftop solar PV on homes, subject to size and placement limits.

What happens to excess electricity?

Unused electricity is exported to the grid, and you receive a payment from your energy supplier under Ireland’s Clean Export Guarantee (CEG).
