What Kirkwall homeowners ask about solar
How much do solar panels cost in Kirkwall?
A 3-4kWp system in Kirkwall typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 3,120 kWh/year, paying for itself in 6-8 years.
How does shading affect solar panels in Kirkwall?
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.
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 happens during a power cut?
Standard grid-tied solar systems shut down during a power cut for safety reasons (to protect engineers working on the grid). If you need backup power, you can install a hybrid inverter with battery storage that provides power during outages.
