How do solar panels work in 3 simple steps?
Solar panels convert sunlight into electricity using photovoltaic cells. An inverter converts the DC output to 230V AC for your home. Surplus energy is exported to the grid for 15–32c/kWh. In Ireland, a 4kWp system covers 80–100% of average household use. Here’s how to get started:

Which Irish counties get the most solar energy?
Ireland’s southeast counties — Wexford, Waterford, and Kilkenny — lead with solar yields of 920–965 kWh/kWp per year. However, even the lowest-ranked counties exceed 817 kWh/kWp, making solar panels worthwhile everywhere in Ireland. A 4kWp system generates 3,270–3,860 kWh annually depending on location.

Frequently Asked Questions About Solar Panels in Ireland
What is solar power?
Solar power is electricity generated from sunlight using photovoltaic (PV) panels. Solar energy — the radiant light and heat from the sun — is converted into usable electricity for your home. In Ireland, solar PV systems can generate 80–100% of a typical household's electricity needs, even with our climate.
How do solar panels work?
Solar panels contain silicon cells that convert sunlight into direct current (DC) electricity. An inverter converts this to alternating current (AC) at 230V for your home. Any surplus is exported to the grid for a feed-in payment of 15–32c/kWh, or stored in a battery.
Are solar panels worth it in Ireland?
Yes. With the SEAI grant of up to €1,800, 0% VAT, and feed-in tariffs, a typical solar panel system pays for itself in 4–6 years and generates free electricity for 25+ years. Over 155,000 Irish homes have already installed solar panels.
How much are solar panels in Ireland?
A typical 4.4 kWp system (10 panels) costs approximately €7,700 before the SEAI grant, or around €5,900 after the €1,800 grant. 0% VAT applies to residential installations. Prices vary by installer and equipment.
How many solar panels do I need?
Most Irish homes need 8–12 panels (3.5–5.3 kWp). The sweet spot is 10 panels (4.4 kWp), which maximises the SEAI grant and covers 80–100% of average household electricity. Use our solar calculator for a personalised estimate.
How long do solar panels last?
Modern solar panels last 25–30 years. Performance degrades slowly at 0.3–0.5% per year, so after 25 years they still produce 85–90% of their original output. Inverters typically last 10–15 years. Batteries are warranted for 10–12 years.
