What Girvan homeowners ask about solar
How much do solar panels cost in Girvan?
A 3-4kWp system in Girvan typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 3,340 kWh/year, paying for itself in 6-8 years.
What size solar system do I need for my home in Girvan?
Most homes in Girvan benefit from a 3-6 kWp system. A 4kWp system (10 panels) covers 88% of average household electricity use. Your installer will assess your roof space, orientation, and energy usage to recommend the optimal size.
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.
Do I need to clean my solar panels?
In most cases, rain keeps solar panels clean enough in the UK. 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.
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 UK homes, solar PV is the better investment: it's more versatile, benefits from 0% VAT, and you can sell excess electricity via the SEG. Solar thermal only heats water.
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.
Can I get solar panels on an east or west facing roof in Girvan?
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.
