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. The system generates approximately 3,920 kWh/year, paying for itself in 6-8 years.
Can I add a battery to my solar system?
Yes. A home battery (typically 5-10 kWh) stores excess solar electricity for evening use. This increases your self-consumption from around 30-40% to 60-80%. Batteries currently cost £3,000-£6,000 and also benefit from 0% VAT.
What happens to my solar panels if I move house in Melksham?
Solar panels stay with the property as a permanent fixture. They add value to your home for the next buyer. Your installer can transfer monitoring accounts to the new owner.
Do solar panels increase property value in Melksham?
Yes. Solar panels improve your EPC rating and can increase property value by up to 4%. Buyers increasingly look for energy-efficient homes with lower running costs. A solar system in Melksham is a long-term investment in your property.
How long do solar panels last?
Modern solar panels are warrantied for 25-30 years and typically last even longer. Panel efficiency degrades by about 0.5% per year, so after 25 years, your panels will still produce around 87% of their original output. Inverters typically last 10-15 years and may need one replacement.
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. Many installers recommend splitting panels across east and west to spread generation throughout the day, which can actually improve self-consumption.
Do I need planning permission for solar panels?
Most residential solar installations in the UK are permitted development and don't require planning permission, provided panels don't project more than 200mm from the roof surface. Listed buildings and conservation areas may have additional requirements.
