Your solar questions for Porthcawl
How much do solar panels cost in Porthcawl?
A 3-4kWp system in Porthcawl typically costs £5,000-£8,000 with 0% VAT included — the zero-rate VAT alone saves around £1,000 compared to the standard 20% rate. The system generates approximately 3,500 kWh/year, paying for itself in 6-8 years through electricity savings and Smart Export Guarantee income of 4-6p/kWh. Adding a home battery (5-10 kWh) costs an additional £3,000-£6,000 and also benefits from 0% VAT. We recommend getting at least three quotes from MCS-certified installers to compare pricing and equipment.
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 4-6p/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 solar panels increase property value in Porthcawl?
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 28p/kWh. A solar system in Porthcawl 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.
Can I sell excess solar electricity?
Yes. Under the UK's Smart Export Guarantee (SEG), licensed suppliers with 150,000+ customers must offer a tariff for surplus electricity you export to the grid. Typical rates are 4-6p/kWh, with some suppliers offering up to 15p/kWh on time-of-use tariffs. You need a smart meter and an MCS-certified installation to be eligible — your supplier will install a smart meter for free if needed. A typical 4kWp system without battery storage exports around 50-70% of its generation, providing a meaningful income stream alongside electricity bill savings.
Do solar panels work in winter in Bridgend?
Yes, solar panels generate electricity all year round, including during winter months. While output is lower from November to February, Bridgend still receives usable daylight hours even in December, and panels work from diffused light on cloudy days. Annual generation figures (3,500 kWh for a 4kWp system) already account 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.
What size solar system do I need for my home in Porthcawl?
Most homes in Porthcawl benefit from a 3-6 kWp system. A 4kWp system (10 panels at ~400W each) covers 93% of average household electricity use and requires approximately 18-20 m² of unshaded roof space. If you have an electric vehicle or heat pump, a larger 5-6 kWp system (12-15 panels) may be more appropriate to offset the additional demand. Your MCS-certified installer will assess your roof space, orientation, shading, and electricity consumption to recommend the optimal size during a site survey.
Do I need a smart meter for solar panels?
A smart meter is required to sell surplus electricity back to the grid under the Smart Export Guarantee (SEG) and earn 4-6p/kWh for your exports. Your energy supplier will install a smart meter for free if you do not already have one — contact them before or shortly after your solar installation. You do not strictly need a smart meter for the solar panels themselves to work, but without one you cannot receive SEG payments. Your MCS-certified installer submits the G98/G99 application to your Distribution Network Operator after installation to register your system for grid export.
