What Llanrwst homeowners ask about solar
How much do solar panels cost in Llanrwst?
A 3-4kWp system in Llanrwst typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 3,440 kWh/year, paying for itself in 6-8 years.
What size solar system do I need for my home in Llanrwst?
Most homes in Llanrwst benefit from a 3-6 kWp system. A 4kWp system (10 panels) covers 90% of average household electricity use. Your installer will assess your roof space, orientation, and energy usage to recommend the optimal size.
How does shading affect solar panels in Llanrwst?
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 I need a smart meter for solar panels?
You need a smart meter to sell surplus electricity back to the grid under the Smart Export Guarantee (SEG). Your energy supplier will install a smart meter for free. Your installer submits the G98/G99 application to your DNO after installation.
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 solar panels work in winter in Conwy?
Yes, solar panels generate electricity all year round. While output is lower in winter, Conwy still receives usable daylight hours even in December. Annual generation figures (3,440 kWh for a 4kWp system) already account for seasonal variation.
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.
