Are solar panels worth it in Duncannon?

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 add a battery to my solar system?
Yes. A home battery (typically 5-10 kWh) stores excess solar electricity for evening use. This increases your self-consumption from around 30-40% to 60-80%. Batteries currently cost €3,000-€6,000 and are not yet covered by the SEAI grant.
Do I need to clean my solar panels?
In most cases, rain keeps solar panels clean enough in Ireland. If your panels are near trees or at a low angle, an annual clean may improve output by 2-5%. Never use abrasive materials — a soft brush and water is sufficient.
