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
Solar panel cleaning has become a standard part of maintaining domestic and commercial solar systems across the UK. While rain does help keep panels partially clean, it does not remove stubborn build-up such as bird droppings, algae, traffic film, or pollen residue. Over time, this
Solar panels are designed to be low-maintenance, but “low-maintenance” does not mean “no maintenance”. Over time, panels naturally collect dirt, dust, pollen, bird droppings, traffic film, and other environmental debris. In the UK, where weather conditions range from heavy rain to dry, dusty spells and
