Solar panels naturally degrade over time, typically losing about 0. 5–1% efficiency per year, but quality panels can still perform well for 25–30 years. Heat, poor maintenance, partial shading, and low-quality materials are the leading causes of faster solar panel degradation. . Solar panel degradation comprises a series of mechanisms through which a PV module degrades and reduces its efficiency year after year. What's Solar Panel Degradation? Solar panel performance degradation refers to the gradual decline in a solar panel's. . Because even a small decline in efficiency impacts how much electricity your system generates, your solar investment payback period, and ultimately, your long-term return on investment (ROI). Understanding how and why this happens can help you make informed decisions about your solar energy investment.
