Frequently Asked Questions About Solar Panels in Deganwy
How much do solar panels cost in Deganwy?
A 3-4kWp system in Deganwy 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 is an EPC assessment and do I need one?
An Energy Performance Certificate (EPC) assessment rates your home's energy efficiency from A to G. While not required for solar installation, solar panels typically improve your EPC by 1-2 grades, which can increase your property value. An EPC costs around £60-£120.
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.
Are solar panels worth it in Deganwy?
Yes. With estimated savings of £963+ per year, 0% VAT, and export income of 3-15p/kWh through the Smart Export Guarantee (SEG), a solar system in Deganwy pays for itself in 6-8 years and lasts 25+ years.
How long does solar panel installation take?
A typical residential installation takes 1-2 days. This includes scaffolding, mounting the panels, wiring, inverter installation, and connecting to the grid. Your installer handles the DNO notification (G98/G99 application).
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 size solar system do I need for my home in Deganwy?
Most homes in Deganwy benefit from a 3-6 kWp system. A 4kWp system (10 panels) covers 91% of average household electricity use. Your installer will assess your roof space, orientation, and energy usage to recommend the optimal size.
