Are solar panels worth it in Rathowen?
Yes. With estimated savings of €1045+ per year, the €1,800 SEAI grant, 0% VAT, and export income of 15-25c/kWh, a solar system in Rathowen pays for itself in 4-6 years and lasts 25+ years.
How long do solar panels last?
Modern solar panels are warrantied for 25-30 years and typically last even longer. Panel efficiency degrades by about 0.5% per year — so after 25 years, your panels will still produce around 87% of their original output. Inverters typically last 10-15 years and may need one replacement.
What is the difference between solar PV and solar thermal?
Solar PV panels generate electricity from sunlight. Solar thermal panels heat water directly. For most Irish homes, solar PV is the better investment — it's more versatile, qualifies for the SEAI grant, and you can sell excess electricity. Solar thermal only heats water.
Can I get solar panels on an east or west facing roof in Rathowen?
Yes. East or west-facing roofs still produce 80-85% of the output of a south-facing roof. Many installers recommend splitting panels across east and west to spread generation throughout the day, which can actually improve self-consumption.
