Common Questions About Going Solar in Colwyn Bay
How much do solar panels cost in Colwyn Bay?
A 3-4kWp system in Colwyn Bay 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 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.
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.
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 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.
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.
Is my roof suitable for solar panels in Colwyn Bay?
Most roofs are suitable. You need at least 15-20 m² of unshaded roof space for a typical 4kWp system (10 panels). South, east, or west-facing roofs work well. Your installer will assess your roof's orientation, angle, and structural suitability during a site survey.
