Solar Panels in Pewsey, Wiltshire

A 4kWp system in Pewsey 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 Pewsey's solar yield of 980 kWh/kWp, a 4kWp system generates approximately 3,920 kWh/year, paying for itself in 11-13 years through electricity savings of £698+/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.

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.

Yes. With a solar yield of 980 kWh/kWp and estimated savings of £698+ per year at current electricity rates of around 25p/kWh, 0% VAT saving approximately £1,300-£1,700 on installation, and export income of around 13-15p/kWh through the Smart Export Guarantee (SEG), a solar system in Pewsey pays for itself in 11-13 years. Wiltshire ranks #9 of 102 UK counties for solar yield, which is about as good as it gets for generation in Pewsey. After payback, you benefit from 12-19 years of near-free electricity as panels last 25-30 years. Total lifetime savings typically reach £15,000-£18,000 depending on your electricity usage and self-consumption rate.

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, Wiltshire still receives usable daylight hours even in December, and panels work from diffused light on cloudy days. With 1,620 sunshine hours per year, the annual generation figure of 3,920 kWh for a 4kWp system in Pewsey 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.

Based on PVGIS satellite data for Pewsey's coordinates, a 4kWp system generates approximately 3,920 kWh per year at a yield of 980 kWh/kWp, covering 103% of average household use (3,800 kWh/year). The area receives around 1,620 sunshine hours annually. Wiltshire ranks #9 of 102 UK counties for solar yield, which is about as good as it gets for generation in Pewsey. 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.
