Solar panels degrade slowly, losing about 0. 5% output per year, and often last 25–30 years or more. Most residential panels in 2025 are rated 250–550 watts, with 400-watt models becoming the new standard. Panel efficiency and longevity stand as critical factors shaping sustainability in the solar industry. Quality of materials and installation practices greatly affect how quickly solar panels degrade. Ultraviolet exposure, thermal cycling, and weathering all contribute to reduced efficiency. Manufacturers typically warrant that output will not drop more than a certain percentage—often around 0.
