Frequently Asked Questions About Solar Panels in Erskine
How much do solar panels cost in Erskine?
A 3-4kWp system in Erskine typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 3,260 kWh/year, paying for itself in 6-8 years.
What is an EPC assessment and do I need one?
An Energy Performance Certificate (EPC) assessment rates your home's energy efficiency from A to G. While not required for solar installation, solar panels typically improve your EPC by 1-2 grades, which can increase your property value. An EPC costs around £60-£120.
How does shading affect solar panels in Erskine?
Shading from trees, chimneys, or nearby buildings can reduce output significantly. Modern systems use optimisers or microinverters so that shading on one panel doesn't drag down the whole system. Your installer will assess shading during the site survey.
What is the Smart Export Guarantee (SEG)?
The Smart Export Guarantee (SEG) requires licensed energy suppliers to offer a tariff to small-scale generators for electricity exported to the grid. Rates are typically 3-15p/kWh. You need a smart meter and an MCS-certified installation to be eligible.
What is the difference between solar PV and solar thermal?
Solar PV panels generate electricity from sunlight. Solar thermal panels heat water directly. For most UK homes, solar PV is the better investment: it's more versatile, benefits from 0% VAT, and you can sell excess electricity via the SEG. Solar thermal only heats water.
What happens during a power cut?
Standard grid-tied solar systems shut down during a power cut for safety reasons (to protect engineers working on the grid). If you need backup power, you can install a hybrid inverter with battery storage that provides power during outages.
Are solar panels worth it in Erskine?
Yes. With estimated savings of £911+ per year, 0% VAT, and export income of 3-15p/kWh through the Smart Export Guarantee (SEG), a solar system in Erskine pays for itself in 6-8 years and lasts 25+ years.
