Frequently Asked Questions About Solar Panels in Sidmouth
How much do solar panels cost in Sidmouth?
A 3-4kWp system in Sidmouth typically costs £5,000-£8,000 with 0% VAT. The system generates approximately 4,240 kWh/year, paying for itself in 6-8 years.

Is my roof suitable for solar panels in Sidmouth?
Most roofs are suitable. You need at least 15-20 m² of unshaded roof space for a typical 4kWp system (10 panels). South, east, or west-facing roofs work well. Your installer will assess your roof's orientation, angle, and structural suitability during a 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.
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.
Do solar panels work in winter in Devon?
Yes, solar panels generate electricity all year round. While output is lower in winter, Devon still receives usable daylight hours even in December. Annual generation figures (4,240 kWh for a 4kWp system) already account for seasonal variation.
How does shading affect solar panels in Sidmouth?
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.
