Common Questions from First-Time Solar Buyers in Ireland

Thinking about going solar for the first time? You’re not alone. Across Dublin, Cork, and the rest of Ireland, more homeowners are making the switch to solar PV systems to save on electricity bills and reduce carbon emissions. But if you’ve never installed solar before, it’s natural to have questions.

Here, we answer the most common queries from first-time solar buyers in Ireland. So you can move forward with confidence.

1. How much does a solar panel system cost in Ireland?

The cost of a solar PV system for a typical Irish home usually ranges from €5,000 to €12,000, depending on:

• The size of the system (number of panels)
• Whether you add battery storage
• The complexity of the installation
• SEAI grants can reduce your upfront costs by up to €1,800 for homeowners.

2. How long do solar panels last?

Most high-quality solar panels last 25–30 years and come with performance warranties to ensure they still produce 80–85% of their original output after two decades. Inverters generally last 10–15 years and may need replacing during the system’s lifetime.

3. Do I need planning permission?

For most homes in Ireland, solar PV installations do not require planning permission, as long as they meet certain size and placement guidelines. Exceptions may apply for listed buildings or homes in protected areas.

4. Will solar panels work in Irish weather?

Absolutely. Solar panels generate electricity from daylight, not direct heat, so they work year-round, even on cloudy days. While output is higher in summer, a well-designed system in Ireland can provide 70–80% of a household’s annual electricity needs.

5. Can I store excess solar power?

Yes. A home battery allows you to store surplus solar energy for use later, such as at night or during peak electricity times. This can increase your savings and help you get the most out of your system.

6. Can I sell electricity back to the grid?

Yes. Under the Microgeneration Support Scheme (MSS), Irish homeowners can earn money for exporting excess electricity to the grid via the feed-in tariff offered by their energy supplier.

7. How long does installation take?

Once your system is designed and your grant application is approved, most installations take just 1–2 days. More complex systems with batteries or roof reinforcements may take a little longer.

8. What maintenance is needed?

Solar PV systems require minimal maintenance. Regular visual inspections and occasional cleaning are usually all that’s needed. Your installer will also provide safety checks and monitoring to ensure optimal performance.

9. How quickly will I see savings?

Most homeowners notice a drop in electricity bills immediately after switching to solar. The payback period is typically 5–7 years, after which your electricity is essentially free (minus occasional maintenance).
