Common Questions About Going Solar in Didcot
How much do solar panels cost in Didcot?
A 3-4kWp system in Didcot typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 3,820 kWh/year, paying for itself in 6-8 years.
Can I get solar panels on an east or west facing roof in Didcot?
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 solar panels work in winter in Oxfordshire?
Yes, solar panels generate electricity all year round. While output is lower in winter, Oxfordshire still receives usable daylight hours even in December. Annual generation figures (3,820 kWh for a 4kWp system) already account for seasonal variation.
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.
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 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.
Are solar panels worth it in Didcot?
Yes. With estimated savings of £1075+ per year, 0% VAT, and export income of 3-15p/kWh through the Smart Export Guarantee (SEG), a solar system in Didcot pays for itself in 6-8 years and lasts 25+ years.
