Solar Panels in Cumnock, East Ayrshire

A 3-4kWp system in Cumnock 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. The system generates approximately 3,320 kWh/year, paying for itself in 6-8 years through electricity savings 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.

A smart meter is required to sell surplus electricity back to the grid under the Smart Export Guarantee (SEG) and earn 4-6p/kWh for your exports. Your energy supplier will install a smart meter for free if you do not already have one — contact them before or shortly after your solar installation. You do not strictly need a smart meter for the solar panels themselves to work, but without one you cannot receive SEG payments. Your MCS-certified installer submits the G98/G99 application to your Distribution Network Operator after installation to register your system for grid export.

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.

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.

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.

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.

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.
