How Much Do Solar Panels Cost in Ireland in 2025?

The Installation cost of solar panels in Ireland in 2025 depends on size of the system and the type of house, but overall, prices have become more affordable then ever. For most houses a typical solar PV system ranges from 2.64kWp to 8.8kWp which is enough to power the average Irish household. After applying the SEAI grant which can reduces the cost up to €1800, homeowners can expect to pay between €7400 to €11400, excluding government grant. Small terraced houses, may only need a 3kWp to 4kWp system, while large detached homes might requires 5kWp to 8kWp or more to cover the energy needs.

Installation cost usually include the panels, inverter, mounting equipment, and labour charge. if you choose to add battery storage system as a option (around €1,700 – €2,400) or an EV charger (roughly €1,000 -€1,500) the total price will be higher, but these extras can give you more control over your energy use and boost your savings in the long run. Overall, with the grants in place and VAT set at 0%, 2025 is a great year to invest in solar at a lower cost than previous years.

Factors Affecting Solar Panels Cost ?

When considering solar panels installation in Ireland, there is several factors which affect the price of solar systems.

System Size and Energy Needs

The size of the solar PV system significantly impacts both the upfront cost and the potential energy savings. Large system with more panels will generate more electricity but require higher initial investment. For example, 2kWp to 4kWp system will cost between €4999 to €8999, while 5kWp to 8kWp system will cost €9,000 to €14,000 including government grant.

Panel type and quality

The efficiency and durability of solar panels depends on the type- Monocrystalline panels, known for higher efficiency and longer lifespan, may have a higher price but offer better performance over time. Polycrystalline panels are more cost effective but have slightly lower efficiency.

Installation Complexity

The structure, angle, and accessibility of roof can impact labour costs. complex installations require more time and resources, thereby increasing the overall system price.

Additional Components

Batteries and EV chargers: It can increase the total system price but enhance energy utilisation and storage capabilities. solar batteries ranges from €1,700 to €2,400 and EV charges cost approximately €1,000 to €1,500.

Blackout protection: For houses in a areas prone to outages, blackout protection is an excellent upgrade. With a compatible battery and specific wiring, you can keep essential appliances running even when the grid is down.

Changeover switch: standard solar systems automatically shut down during a power cut to protect utility workers. A changeover switch allows to safely disconnect from the grid and draw energy from solar battery or panels. This setup requires a hybrid inverter and battery system but offers greater energy independence and security.

Power Diverter for Hot Water: Power
diverter a device which use extra unused solar electricity into heating
water. It helps to reduce reliance on gas or electric heaters. These
devices cost around €500 with top rated models like myenergi eddi offering great performance.

Real Time Energy monitoring: some systems include live monitoring tools, allowing users to track solar production and energy usage in real time. This helps optimise usage habits and spot any underperformance early.

How to get the Most Value from Solar Panels in Ireland

Solar panels in Ireland are now a dependable source of energy. They have become a smart and popular way to lower your electricity bills and use less power from the grid. But to get the most value from your solar system over time, it’s important to think about more than just the upfront cost. Once your panels are installed, they generate free power from the sun, helping to reduce your monthly bills. There are also grants available in Ireland to help cover the cost of installation. If your system produces more electricity than you use, you can sell the extra power back to the grid. Adding a battery allows you to store solar energy for use at night or during power cuts, which can further increase your savings. As energy prices continue to rise, the long-term savings from solar panels become even greater.

Four Smart Way Solar Panels Save You Money

Generate Free Electricity: Solar panels reduce your reliance on the grid by producing clean energy. In Ireland, they can cover up to 70% of a home’s electricity needs, saving up to €1,000 per year.

Sell Excess energy: Excess energy produced, especially in summer, can be sold back to the grid through Ireland’s Microgeneration Support Scheme, earning you credits on your bill.

Shift Usage with Battery Storage: A battery lets you store cheap night-time electricity or excess solar power for daytime use. Charging during off-peak hours (like 2–4 am) means big savings — even when it’s cloudy.

Monitor and Save: Solar apps help you track energy use in real time. This insight often changes habits — like using appliances during cheaper hours — and leads to smarter, more efficient energy use.
