Is my roof suitable for solar panels in Carlisle?
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.

How does shading affect solar panels in Carlisle?
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 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 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.
What is the payback period for solar panels in Carlisle?
With a cost of £5,000-£8,000 (0% VAT) and savings of £958+ per year plus SEG export income, a typical solar system in Carlisle pays for itself in 6-8 years. After payback, you get 20+ years of near-free electricity.
