Frequently Asked Questions About Solar Panels in Blaenau Ffestiniog

A 3-4kWp system in Blaenau Ffestiniog typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 3,440 kWh/year, paying for itself in 6-8 years.
Do solar panels work in winter in Gwynedd?
Yes, solar panels generate electricity all year round. While output is lower in winter, Gwynedd still receives usable daylight hours even in December. Annual generation figures (3,440 kWh for a 4kWp system) already account for seasonal variation.
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 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.
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.
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.
