Solar Panels in Glastonbury, Somerset

A 3-4kWp system in Glastonbury 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 Glastonbury's solar yield of 1003 kWh/kWp, a 4kWp system generates approximately 4,012 kWh/year, paying for itself in 6-8 years through electricity savings of £1123+/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.

Solar PV panels generate electricity from sunlight using photovoltaic cells, while solar thermal panels heat water directly using the sun's warmth. For most UK homes, solar PV is the better investment: it is more versatile (powering all electrical appliances), benefits from 0% VAT, and you can sell excess electricity via the Smart Export Guarantee at 4-6p/kWh. Solar thermal only heats water and does not generate electricity or qualify for SEG income. Solar PV panels also last longer (25-30 years versus 15-20 for solar thermal) and have lower maintenance requirements.

Yes, solar panels generate electricity all year round, including during winter months. While output is lower from November to February, Somerset still receives usable daylight hours even in December, and panels work from diffused light on cloudy days. With 1,650 sunshine hours per year, the annual generation figure of 4,012 kWh for a 4kWp system in Glastonbury 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.

Yes. A home battery (typically 5-10 kWh capacity) stores excess solar electricity generated during the day for evening and overnight use. This increases your self-consumption from around 30-40% to 60-80%, significantly reducing your reliance on grid electricity. Batteries currently cost £3,000-£6,000 and also benefit from 0% VAT on residential installations. Most batteries are warranted for 10-12 years and can be retrofitted to an existing solar system. Popular options include the Tesla Powerwall, GivEnergy, and Fox ESS units.

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.

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.

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 Glastonbury generating 4,012 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.
