Solar panels are designed to be low maintenance, but that does not mean they are maintenance-free. In the UK, panels are constantly exposed to rain, pollen, bird droppings, traffic film, moss spores, and general airborne dirt. Over time, this layer builds up and reduces how
Solar panels are often described as low-maintenance, but that does not mean they are maintenance-free. Over time, dirt, dust, bird droppings, algae, and general atmospheric grime build up on the surface. This layer can reduce efficiency and, in some cases, noticeably impact energy generation. A
Solar panels are widely seen as one of the most effective ways to reduce energy bills and lower carbon emissions, but they are not without limitations. While the benefits are often highlighted, the drawbacks tend to be less clearly explained or are sometimes oversimplified. The
Solar panels are often talked about as “25-year products”, but that’s slightly misleading. The 25-year figure mainly refers to the performance warranty, not the end of life. In reality, most systems continue producing electricity well beyond this point, just at a gradually reduced output. Understanding
What Is the Lifespan of Solar Panels in the UK? Realistic Expectations Solar panels are often described as a long-term investment, and for good reason. Most modern systems installed in the UK are designed to last for decades, but the real-world lifespan depends on a
The “20% rule” for solar panels is a simple way of explaining how much performance loss can be considered acceptable before cleaning or maintenance becomes necessary. In practical terms, it refers to a drop of around 20% in energy output compared to what your system
