Solar Panels in Aylesford, Kent

A 4kWp system in Aylesford 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. Based on Aylesford's solar yield of 1020 kWh/kWp, a 4kWp system generates approximately 4,080 kWh/year, paying for itself in 11-13 years through electricity savings of £726+/yr and Smart Export Guarantee income of around 13-15p/kWh. 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.

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, solar panels generate electricity all year round, including during winter months. While output is lower from November to February, Kent still receives usable daylight hours even in December, and panels work from diffused light on cloudy days. With 1,770 sunshine hours per year, the annual generation figure of 4,080 kWh for a 4kWp system in Aylesford 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.

With a cost of £6,600-£8,500 (0% VAT included) and savings of £726+ per year based on Aylesford's solar yield of 1020 kWh/kWp at current electricity rates of around 25p/kWh, plus Smart Export Guarantee income of around 13-15p/kWh for surplus electricity, a typical solar system in Aylesford pays for itself in 11-13 years. Kent ranks #6 of 102 UK counties for solar yield, which is about as good as it gets for generation in Aylesford. After payback, you benefit from 12-19 years of near-free electricity as panels last 25-30 years. Adding a battery extends self-consumption and can reduce payback further if you use most electricity in the evenings. Total lifetime savings typically reach £15,000-£18,000 depending on your usage pattern.

South-facing roofs at a 30-40° pitch produce the most electricity (100% of potential yield). South-east and south-west roofs produce around 95% of optimal output. East or west-facing roofs still produce 80-85%, and many installers recommend splitting panels across east and west faces to spread generation throughout the day, which can improve self-consumption. North-facing roofs are generally not recommended for solar panels in the UK as they receive significantly less direct sunlight. Your MCS-certified installer will assess your roof orientation during the site survey.

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 around 13-15p/kWh, with some suppliers offering up to 30p/kWh on time-of-use tariffs like Octopus Flux when paired with a battery. 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 50-60% of its generation, providing a meaningful income stream alongside electricity bill savings.

Based on Kent regional data, a 4kWp system generates approximately 4,080 kWh per year at a yield of 1020 kWh/kWp, covering 107% of average household use (3,800 kWh/year). The area receives around 1,770 sunshine hours annually. Kent ranks #6 of 102 UK counties for solar yield, which is about as good as it gets for generation in Aylesford. Output peaks between May and August and is lower in winter, though annual generation figures already account for this seasonal variation. South-facing roofs at a 30-40° pitch achieve optimal yields, while east or west-facing roofs still produce 80-85% of maximum output.
