Solar Panel FAQs for Melksham
How much do solar panels cost in Melksham?
A 3-4kWp system in Melksham 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 Melksham's solar yield of 980 kWh/kWp, a 4kWp system generates approximately 3,920 kWh/year, paying for itself in 6-8 years through electricity savings of £1098+/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.
Can I add a battery to my solar system?
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.
What happens to my solar panels if I move house in Melksham?
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.
Do solar panels increase property value in Melksham?
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 Melksham generating 3,920 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.
How long do solar panels last?
Modern solar panels are warrantied for 25-30 years and typically last even longer with minimal maintenance. Panel efficiency degrades by just 0.3-0.5% per year, so after 25 years, your panels will still produce around 85-90% of their original output. Inverters typically last 10-15 years and may need one replacement over the system's lifetime, costing around £500-£1,000. With a typical payback period of 6-8 years, that leaves 17-22 years of near-free electricity generation. Panels require very little upkeep — UK rainfall keeps them clean in most cases.
Can I get solar panels on an east or west facing roof in Melksham?
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.
