Most modern panels degrade at a rate between 0. 8% per year, depending on quality, materials and environmental conditions. 5%, which means a panel will still deliver about 88% of its original. . The good news, however, is that they degrade very slowly and can produce electricity even decades later! This doesn't alter the fact that solar panels do lose efficiency as time goes on. There are two main reasons for this. The first is that continuous exposure to the sun's ultraviolet rays cause. . Solar panel degradation comprises a series of mechanisms through which a PV module degrades and reduces its efficiency year after year. Not just how long they last, but how well they perform along the way. The predicted progression for the current solar cycle (Cycle 25) is given by the magenta line, with associated uncertainties shown by the shaded regions.
