Common Questions About Going Solar in Woking

A 3-4kWp system in Woking typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 3,900 kWh/year, paying for itself in 6-8 years.
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.
Do solar panels increase property value in Woking?
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 Woking is a long-term investment in your property.
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.
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.
Do I need a smart meter for solar panels?
You need a smart meter to sell surplus electricity back to the grid under the Smart Export Guarantee (SEG). Your energy supplier will install a smart meter for free. Your installer submits the G98/G99 application to your DNO after installation.
Do solar panels work in winter in Surrey?
Yes, solar panels generate electricity all year round. While output is lower in winter, Surrey still receives usable daylight hours even in December. Annual generation figures (3,900 kWh for a 4kWp system) already account for seasonal variation.
