Your solar questions for Port Talbot
How much do solar panels cost in Port Talbot?
A 3-4kWp system in Port Talbot typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 3,480 kWh/year, paying for itself in 6-8 years.
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 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.
What roof direction is best for solar panels in Port Talbot?
South-facing roofs produce the most electricity (100% of potential). South-east and south-west roofs produce around 95%. East or west-facing roofs still produce 80-85%. North-facing roofs are generally not recommended for solar panels in the UK.
What is the Smart Export Guarantee (SEG)?
The Smart Export Guarantee (SEG) requires licensed energy suppliers to offer a tariff to small-scale generators for electricity exported to the grid. Rates are typically 3-15p/kWh. You need a smart meter and an MCS-certified installation to be eligible.
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 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.
