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.
How does shading affect solar panels in Kilmaine?
Shading from trees, chimneys, or nearby buildings can reduce output significantly. Modern systems use optimisers or microinverters so that shading on one panel doesn't drag down the whole system. Your installer will assess shading during the site survey.
What happens during a power cut?
Standard grid-tied solar systems shut down during a power cut for safety reasons (to protect ESB workers). If you need backup power, you can install a hybrid inverter with battery storage that provides power during outages.
