How much electricity will solar panels generate in Knocknagoshel?
Based on Kerry county data, a 4kWp system in Knocknagoshel generates approximately 3,584 kWh per year, covering 70% of average household use (4,200 kWh/year). Kerry receives around 1,246 sunshine hours annually.
Do solar panels work in winter in Kerry?
Yes, solar panels generate electricity all year round. While output is lower in winter, Kerry still receives usable daylight hours even in December. Annual generation figures (3,584 kWh for a 4kWp system) already account for seasonal variation.
How does shading affect solar panels in Knocknagoshel?
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 maintenance do solar panels need?
Solar panels need very little maintenance. Rain keeps them clean in most cases. There are no moving parts. Your inverter may need replacing once in 25 years (10-15 year lifespan). Annual visual checks and occasional cleaning if near trees is all that's needed.
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.
