Frequently Asked Questions About Solar Panels in St Neots
How much do solar panels cost in St Neots?
A 3-4kWp system in St Neots typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 3,780 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.
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.
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.
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.
Do I need to clean my solar panels?
In most cases, rain keeps solar panels clean enough in the UK. If your panels are near trees or at a low angle, an annual clean may improve output by 2-5%. Never use abrasive materials. A soft brush and water is sufficient.
Do solar panels increase property value in St Neots?
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 St Neots is a long-term investment in your property.
