Solar Panels in Peacehaven, East Sussex

A 4kWp system in Peacehaven 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 Peacehaven's solar yield of 1030 kWh/kWp, a 4kWp system generates approximately 4,120 kWh/year, paying for itself in 11-13 years through electricity savings of £733+/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.

The Smart Export Guarantee (SEG) is a UK government scheme that requires licensed energy suppliers with 150,000+ customers to offer a tariff to small-scale generators for surplus electricity exported to the grid. Typical rates are around 13-15p/kWh, with some suppliers offering up to 30p/kWh on time-of-use or agile tariffs (such as Octopus Flux with a battery) that pay more during peak demand. You need a smart meter and an MCS-certified installation to be eligible. Your energy supplier will install a smart meter for free if you do not already have one. The SEG replaced the Feed-in Tariff scheme, which closed to new applicants in 2019.

Yes, solar panels generate electricity all year round, including during winter months. While output is lower from November to February, East Sussex still receives usable daylight hours even in December, and panels work from diffused light on cloudy days. With 1,800 sunshine hours per year, the annual generation figure of 4,120 kWh for a 4kWp system in Peacehaven 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.

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.

Yes. East or west-facing roofs still produce 80-85% of the output of a south-facing roof, making them well worth installing. Many installers recommend splitting panels across east and west faces to spread generation throughout the day, which can improve self-consumption and reduce the amount of electricity exported at the lower SEG rate. East-facing panels generate more in the morning, while west-facing panels peak in the afternoon, both align well with typical household usage patterns. Only north-facing roofs are generally unsuitable for solar in the UK.

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 Peacehaven generating 4,120 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.

Get at least 3 quotes from MCS-certified installers to compare pricing, equipment brands, and warranty terms. Check each company is registered with MCS at mcscertified.com, this certification is required for Smart Export Guarantee eligibility. Look for 25-year panel performance warranties and 10-15-year inverter warranties as a minimum. Ensure your installer includes the DNO notification (G98/G99 application) and handles all paperwork. Remember that 0% VAT applies automatically to residential installations, so you should not be charged any VAT on the total cost.
