Common Questions About Going Solar in Caldicot
How much do solar panels cost in Caldicot?
A 3-4kWp system in Caldicot typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 3,540 kWh/year, paying for itself in 6-8 years.
Can I sell excess solar electricity?
Yes. Under the UK's Smart Export Guarantee (SEG), you can sell surplus electricity at 3-15p/kWh. You need a smart meter and an MCS-certified installation. Your energy supplier pays you for every unit exported to the grid.
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.
How does shading affect solar panels in Caldicot?
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.
What is the payback period for solar panels in Caldicot?
With a cost of £5,000-£8,000 (0% VAT) and savings of £997+ per year plus SEG export income, a typical solar system in Caldicot pays for itself in 6-8 years. After payback, you get 20+ years of near-free electricity.
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.
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.
