Solar Panels in Wellington, Somerset

A 3-4kWp system in Wellington 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 Wellington's solar yield of 1000 kWh/kWp, a 4kWp system generates approximately 4,000 kWh/year, paying for itself in 6-8 years through electricity savings of £1120+/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. With a solar yield of 1000 kWh/kWp and estimated savings of £1120+ per year at current electricity rates of 28p/kWh, 0% VAT saving approximately £1,000 on installation, and export income of 4-6p/kWh through the Smart Export Guarantee (SEG), a solar system in Wellington pays for itself in 6-8 years. Somerset ranks #7 of 102 UK counties for solar yield, putting Wellington in an excellent position for solar energy. After payback, you benefit from 17-22 years of near-free electricity as panels last 25-30 years. Total lifetime savings typically reach £15,000-£25,000 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 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.

Solar panels need very little maintenance over their 25-30 year lifespan. UK rainfall keeps them clean in most cases, and there are no moving parts to wear out. Your inverter may need replacing once during the system's lifetime (10-15 year lifespan, costing around £500-£1,000). An annual visual check to ensure no debris, bird nesting, or damage is recommended, along with occasional cleaning if panels are near trees or at a low pitch angle. Some installers offer maintenance packages, but these are generally optional rather than essential.

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.

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.

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.
