Solar Panel FAQs for Ventnor
How much do solar panels cost in Ventnor?
A 3-4kWp system in Ventnor typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 4,280 kWh/year, paying for itself in 6-8 years.
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.
Do solar panels work in winter in Isle of Wight?
Yes, solar panels generate electricity all year round. While output is lower in winter, Isle of Wight still receives usable daylight hours even in December. Annual generation figures (4,280 kWh for a 4kWp system) already account for seasonal variation.
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.
How long do solar panels last?
Modern solar panels are warrantied for 25-30 years and typically last even longer. Panel efficiency degrades by about 0.5% per year, so after 25 years, your panels will still produce around 87% of their original output. Inverters typically last 10-15 years and may need one replacement.
Can I get solar panels on an east or west facing roof in Ventnor?
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.
How does shading affect solar panels in Ventnor?
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.
