Dunmurry solar panel questions answered
How much do solar panels cost in Dunmurry?
A 3-4kWp system in Dunmurry typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 3,260 kWh/year, paying for itself in 6-8 years.
How do I get the best deal on solar panels in Dunmurry?
Get at least 3 quotes from MCS-certified installers. Check they are registered with MCS at mcscertified.com. Compare pricing, equipment brands, and warranties. Ensure your installer handles the DNO notification (G98/G99 application).
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.
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.
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.
How does shading affect solar panels in Dunmurry?
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 Dunmurry?
With a cost of £5,000-£8,000 (0% VAT) and savings of £913+ per year plus SEG export income, a typical solar system in Dunmurry pays for itself in 6-8 years. After payback, you get 20+ years of near-free electricity.
