Solar Panel FAQs for Comber
How much do solar panels cost in Comber?
A 3-4kWp system in Comber typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 3,240 kWh/year, paying for itself in 6-8 years.
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.
What maintenance do solar panels need?
Solar panels need very little maintenance. Rain keeps them clean in most cases. There are no moving parts. Your inverter may need replacing once in 25 years (10-15 year lifespan). Annual visual checks and occasional cleaning if near trees is all that's needed.
Can I add a battery to my solar system?
Yes. A home battery (typically 5-10 kWh) stores excess solar electricity for evening use. This increases your self-consumption from around 30-40% to 60-80%. Batteries currently cost £3,000-£6,000 and also benefit from 0% VAT.
Do solar panels work in winter in Down?
Yes, solar panels generate electricity all year round. While output is lower in winter, Down still receives usable daylight hours even in December. Annual generation figures (3,240 kWh for a 4kWp system) already account for seasonal variation.
What size solar system do I need for my home in Comber?
Most homes in Comber benefit from a 3-6 kWp system. A 4kWp system (10 panels) covers 85% of average household electricity use. Your installer will assess your roof space, orientation, and energy usage to recommend the optimal size.
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.
