Your solar questions for Exmouth
How much do solar panels cost in Exmouth?
A 3-4kWp system in Exmouth 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 Exmouth's solar yield of 1066 kWh/kWp, a 4kWp system generates approximately 4,264 kWh/year, paying for itself in 6-8 years through electricity savings of £1194+/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.
Do I need to clean my solar panels?
In most cases, regular UK rainfall keeps solar panels clean enough to perform well. If your panels are near trees, under bird flight paths, or at a low pitch angle (below 15°), an annual clean may improve output by 2-5%. Never use abrasive materials, pressure washers, or household cleaning products — a soft brush and clean water is sufficient. Professional panel cleaning services typically cost £50-£100 per visit. Your panels have no moving parts and require very little maintenance over their 25-30 year lifespan.
Can I get solar panels on an east or west facing roof in Exmouth?
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.
Do I need planning permission for solar panels?
Most residential solar installations in the UK are classed as permitted development and do not require planning permission, provided panels do not project more than 200mm from the roof surface. Listed buildings, conservation areas, Areas of Outstanding Natural Beauty (AONBs), and World Heritage Sites may have additional requirements from your local planning authority. Ground-mounted systems are also permitted development if they do not exceed 9m² in area. Your MCS-certified installer can advise on any local restrictions that apply to your property.
How long does solar panel installation take?
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.
Do solar panels increase property value in Exmouth?
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 28p/kWh. A solar system in Exmouth generating 4,264 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.
Do solar panels work in winter in Devon?
Yes, solar panels generate electricity all year round, including during winter months. While output is lower from November to February, Devon still receives usable daylight hours even in December, and panels work from diffused light on cloudy days. With 1,850 sunshine hours per year, the annual generation figure of 4,264 kWh for a 4kWp system in Exmouth 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.
