Solar panels in Clunderwen: common questions
How much do solar panels cost in Clunderwen?
A 4kWp system in Clunderwen typically costs £6,600-£8,500 with 0% VAT included, the zero-rate VAT alone saves around £1,300-£1,700 compared to the standard 20% rate.

Adding a home battery (5-10 kWh) costs an additional £3,000-£6,500 and also benefits from 0% VAT. We recommend getting at least three quotes from MCS-certified installers to compare pricing and equipment.
Do solar panels work in winter in Pembrokeshire?
Yes, solar panels generate electricity all year round, including during winter months. While output is lower from November to February, Pembrokeshire still receives usable daylight hours even in December, and panels work from diffused light on cloudy days. With 1,530 sunshine hours per year, the annual generation figure of 3,368 kWh for a 4kWp system in Clunderwen already accounts for this seasonal variation. Cooler winter temperatures actually improve panel efficiency compared to hot summer days. Adding a battery allows you to store daytime generation for evening use when winter daylight hours are shorter.
Do solar panels increase property value in Clunderwen?
Yes. Solar panels improve your EPC rating by 1-2 grades and can increase property value by up to 4% according to recent UK property market research. Buyers increasingly look for energy-efficient homes with lower running costs, particularly as electricity prices remain high at around 25p/kWh. A solar system in Clunderwen generating 3,368 kWh/yr is a long-term investment in your property that also generates income through the Smart Export Guarantee. With a 25-30 year panel lifespan, future buyers inherit decades of remaining electricity savings.
How long do solar panels last?
Modern solar panels are warrantied for 25-30 years and typically last even longer with minimal maintenance. Panel efficiency degrades by just 0.3-0.5% per year, so after 25 years, your panels will still produce around 85-90% of their original output. Inverters typically last 10-15 years and may need one replacement over the system's lifetime, costing around £900. With a typical payback period of 11-13 years, that leaves 12-19 years of near-free electricity generation. Panels require very little upkeep, UK rainfall keeps them clean in most cases.
What happens to my solar panels if I move house in Clunderwen?
Solar panels stay with the property as a permanent fixture and transfer to the new owner upon sale. They add value to your home, up to 4% according to UK property research, and improve the EPC rating, making the property more attractive to energy-conscious buyers. Your installer can transfer monitoring app accounts and warranty documentation to the new owner. The Smart Export Guarantee registration also transfers with the property. With a 25-30 year lifespan, the next owner inherits many years of remaining electricity savings.
What is the difference between solar PV and solar thermal?
Solar PV panels generate electricity from sunlight using photovoltaic cells, while solar thermal panels heat water directly using the sun's warmth. For most UK homes, solar PV is the better investment: it is more versatile (powering all electrical appliances), benefits from 0% VAT, and you can sell excess electricity via the Smart Export Guarantee at around 13-15p/kWh. Solar thermal only heats water and does not generate electricity or qualify for SEG income. Solar PV panels also last longer (25-30 years versus 15-20 for solar thermal) and have lower maintenance requirements.
Do I need to clean my solar panels?
In most cases, regular UK rainfall keeps solar panels clean enough to perform well. If your panels are near trees, under bird flight paths, or at a low pitch angle (below 15°), an annual clean may improve output by 2-5%. Never use abrasive materials, pressure washers, or household cleaning products, a soft brush and clean water is sufficient. Professional panel cleaning services typically cost £50-£100 per visit. Your panels have no moving parts and require very little maintenance over their 25-30 year lifespan.
