Solar Panel FAQs for Clydach
How much do solar panels cost in Clydach?
A 3-4kWp system in Clydach typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 3,520 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 is the difference between solar PV and solar thermal?
Solar PV panels generate electricity from sunlight. Solar thermal panels heat water directly. For most UK homes, solar PV is the better investment: it's more versatile, benefits from 0% VAT, and you can sell excess electricity via the SEG. Solar thermal only heats water.
How does shading affect solar panels in Clydach?
Shading from trees, chimneys, or nearby buildings can reduce output significantly. Modern systems use optimisers or microinverters so that shading on one panel doesn't drag down the whole system. Your installer will assess shading during the site survey.
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 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.
Can I get solar panels on an east or west facing roof in Clydach?
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.
