Common Questions About Going Solar in Whitstable
How much do solar panels cost in Whitstable?
A 3-4kWp system in Whitstable typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 4,080 kWh/year, paying for itself in 6-8 years.
Can I get solar panels on an east or west facing roof in Whitstable?
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 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.
Are solar panels worth it in Whitstable?
Yes. With estimated savings of £1142+ per year, 0% VAT, and export income of 3-15p/kWh through the Smart Export Guarantee (SEG), a solar system in Whitstable pays for itself in 6-8 years and lasts 25+ years.
What size solar system do I need for my home in Whitstable?
Most homes in Whitstable benefit from a 3-6 kWp system. A 4kWp system (10 panels) covers 107% of average household electricity use. Your installer will assess your roof space, orientation, and energy usage to recommend the optimal size.
How does shading affect solar panels in Whitstable?
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 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.
