Common Questions About Going Solar in Cranbrook
How much do solar panels cost in Cranbrook?
A 3-4kWp system in Cranbrook typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 4,080 kWh/year, paying for itself in 6-8 years.
Can I get solar panels on an east or west facing roof in Cranbrook?
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.
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 solar panels work in winter in Kent?
Yes, solar panels generate electricity all year round. While output is lower in winter, Kent still receives usable daylight hours even in December. Annual generation figures (4,080 kWh for a 4kWp system) already account for seasonal variation.
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 size solar system do I need for my home in Cranbrook?
Most homes in Cranbrook benefit from a 3-6 kWp system. A 4kWp system (10 panels) covers 107% of average household electricity use. Your installer will assess your roof space, orientation, and energy usage to recommend the optimal size.
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.
