Solar Panel Installation FAQs
A 4kWp residential system (approximately 10 panels) costs €5,000 to €8,000 before the SEAI grant. After the grant of approximately €2,100, you pay €3,000 to €6,000 net. A 6kWp system for larger homes costs €7,000 to €10,000 before grant. Adding a 5kWh battery storage system adds €3,000 to €4,500. Prices vary by panel brand, inverter quality, and roof complexity.
Yes. Solar panels work with daylight, not direct sunshine. Ireland receives between 1,100 and 1,600 hours of sunshine per year depending on location, and panels produce electricity even on overcast days (at reduced output). A 4kWp system in Ireland typically generates 3,400 to 4,000 kWh per year, which is 40 to 60% of an average household's consumption. Germany, which gets similar sunlight levels, is the largest solar market in Europe.
A 4kWp system saves most households €600 to €900 per year on electricity bills. The exact amount depends on how much of the generated electricity you use directly (self-consumption) versus export. Electricity you use yourself saves you the full retail rate (approximately 35-40c per kWh). Electricity you export earns a lower rate (approximately 15-24c per kWh depending on your supplier). Maximising self-consumption, by running appliances during the day or adding battery storage, improves your return.
Yes. Under the Clean Export Guarantee (CEG), all electricity suppliers with more than a certain number of customers must offer a payment for exported solar electricity. Rates vary by supplier but typically range from 15 to 24 cent per kWh. Your installer registers you with your supplier as part of the installation process. The income is currently tax-free up to €200 per year for domestic households.
Rooftop solar panels on houses are generally exempt from planning permission in Ireland, provided they do not extend more than 15cm above the roof surface and do not cover more than 50% of the total roof area. There are exceptions for protected structures, buildings in Architectural Conservation Areas, and some apartment developments. Ground-mounted systems may require planning permission depending on size and location. Your installer should confirm exemption status.
For a standard 4kWp system after the SEAI grant, the typical payback period is 4 to 6 years, depending on your electricity usage pattern and how much you self-consume versus export. After payback, the system generates essentially free electricity for its remaining lifespan of 20 to 25+ years. Adding battery storage extends the payback period slightly (by 1-2 years) but increases total lifetime savings.
