Solar Panels in Draperstown, Londonderry

A 3-4kWp system in Draperstown 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 Draperstown's solar yield of 803 kWh/kWp, a 4kWp system generates approximately 3,212 kWh/year, paying for itself in 6-8 years through electricity savings of £899+/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.

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.

Most homes in Draperstown benefit from a 3-6 kWp system. A 4kWp system (10 panels at ~400W each) generates 3,212 kWh/yr at Draperstown's yield of 803 kWh/kWp, covering 85% 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.

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.

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 4-6p/kWh, with some suppliers offering up to 15p/kWh on time-of-use or agile tariffs 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.

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.

With a cost of £5,000-£8,000 (0% VAT included) and savings of £899+ per year based on Draperstown's solar yield of 803 kWh/kWp at current electricity rates of 28p/kWh, plus Smart Export Guarantee income of 4-6p/kWh for surplus electricity, a typical solar system in Draperstown pays for itself in 6-8 years. Londonderry ranks #91 of 102 UK counties, and solar still pays off here thanks to longer summer daylight hours and cooler temperatures that help panels run more efficiently. After payback, you benefit from 17-22 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-£25,000 depending on your usage pattern.
