Solar Panels in Cardigan, Ceredigion

A 3-4kWp system in Cardigan 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. Based on Cardigan's solar yield of 870 kWh/kWp, a 4kWp system generates approximately 3,480 kWh/year, paying for itself in 6-8 years through electricity savings of £974+/yr 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.

An Energy Performance Certificate (EPC) rates your home's energy efficiency from A (most efficient) to G (least efficient). While an EPC is not required for solar panel installation, adding solar panels typically improves your rating by 1-2 grades, which can increase your property value by up to 4%. An EPC assessment costs around £60-£120 and is valid for 10 years. If you are selling or renting your property, an up-to-date EPC is legally required, so having solar panels reflected in your rating is beneficial.

Yes. A home battery (typically 5-10 kWh capacity) stores excess solar electricity generated during the day for evening and overnight use. This increases your self-consumption from around 30-40% to 60-80%, significantly reducing your reliance on grid electricity. Batteries currently cost £3,000-£6,000 and also benefit from 0% VAT on residential installations. Most batteries are warranted for 10-12 years and can be retrofitted to an existing solar system. Popular options include the Tesla Powerwall, GivEnergy, and Fox ESS units.

Most homes in Cardigan benefit from a 3-6 kWp system. A 4kWp system (10 panels at ~400W each) generates 3,480 kWh/yr at Cardigan's yield of 870 kWh/kWp, covering 92% of average household electricity use. The system 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.

Yes, solar panels generate electricity all year round, including during winter months. While output is lower from November to February, Ceredigion still receives usable daylight hours even in December, and panels work from diffused light on cloudy days. With 1,380 sunshine hours per year, the annual generation figure of 3,480 kWh for a 4kWp system in Cardigan 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.

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.

A typical residential installation takes 1-2 days of on-site work. This includes erecting scaffolding, mounting the panels on roof brackets, wiring, inverter installation, and connecting to your consumer unit. The full process from initial survey to completed installation usually takes 2-6 weeks depending on installer availability and DNO requirements. Your MCS-certified installer handles the DNO notification (G98 for systems under 3.68 kW, G99 for larger systems) and all associated paperwork on your behalf.
