If you’re considering installing solar panels in Worksop, Nottinghamshire, or across South Yorkshire, one question you might have is: “How long do solar panels last?” The good news is that while solar panels do degrade over time, the impact is minor—and it shouldn’t deter you from making a long-term investment in solar energy.
Solar panel degradation refers to the gradual decline in performance as panels age. Research shows that the average degradation rate is about 0.5% per year. That means after 20 years, your panels will still generate around 90% of their original output. In a recent article by SolarQuotes, independent data supported these findings across numerous panel brands and installations.
“We only install products that meet the highest standards. Degradation is normal, but with good-quality panels and proper installation, it’s minimal,” says Lee Rolfe, Managing Director at Wright Renewables.
Several factors influence how quickly a panel degrades:
Even after two decades, most solar systems continue to produce reliable energy, helping reduce your electricity bills and carbon footprint. Most panels come with 25 to 30-year performance warranties, offering extra peace of mind.
At Wright Renewables, we support you beyond installation with:
“Degradation is simply part of a panel’s natural life. With today’s technology, it’s hardly noticeable—and the benefits far outweigh the drop in output,” adds Adam Roberts, Development Directer, Wright Renewables
Going solar is still one of the smartest energy decisions you can make. With rising energy costs, increasing incentives, and the growing push for decarbonisation, solar panel installation in Nottinghamshire and South Yorkshire is more valuable than ever.
