Your solar questions for Pontardulais
How much do solar panels cost in Pontardulais?
A 3-4kWp system in Pontardulais typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 3,520 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.
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 solar panels increase property value in Pontardulais?
Yes. Solar panels improve your EPC rating and can increase property value by up to 4%. Buyers increasingly look for energy-efficient homes with lower running costs. A solar system in Pontardulais is a long-term investment in your property.
What size solar system do I need for my home in Pontardulais?
Most homes in Pontardulais benefit from a 3-6 kWp system. A 4kWp system (10 panels) covers 92% 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 Pontardulais?
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 Swansea?
Yes, solar panels generate electricity all year round. While output is lower in winter, Swansea still receives usable daylight hours even in December. Annual generation figures (3,520 kWh for a 4kWp system) already account for seasonal variation.
