Your solar questions for Kilwinning
How much do solar panels cost in Kilwinning?
A 3-4kWp system in Kilwinning typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 3,320 kWh/year, paying for itself in 6-8 years.
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.
Can I sell excess solar electricity?
Yes. Under the UK's Smart Export Guarantee (SEG), you can sell surplus electricity at 3-15p/kWh. You need a smart meter and an MCS-certified installation. Your energy supplier pays you for every unit exported to the grid.
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.
How does shading affect solar panels in Kilwinning?
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.
Do solar panels work in winter in North Ayrshire?
Yes, solar panels generate electricity all year round. While output is lower in winter, North Ayrshire still receives usable daylight hours even in December. Annual generation figures (3,320 kWh for a 4kWp system) already account for seasonal variation.
What roof direction is best for solar panels in Kilwinning?
South-facing roofs produce the most electricity (100% of potential). South-east and south-west roofs produce around 95%. East or west-facing roofs still produce 80-85%. North-facing roofs are generally not recommended for solar panels in the UK.
