Solar panel degradation rates vary based on factors like panel quality, technology, and environmental conditions. On average, high-quality solar panels degrade at a rate of 0.3% to 0.5% per year. This means that after 25 years, a well-maintained solar panel might still operate at around 85% to 90% of its original efficiency.
A typical degradation rate for solar panels is between 0.5% and 0.8% per year. This means that a panel might produce 12-15% less power after 25 years compared to when it was first installed.

The degradation of a PV (photovoltaic) module is the term used to describe the steady decline in efficiency and output power of a solar panel over time as a result of numerous environmental influences, manufacturing flaws, and material degradation.
Solar panel degradation is a gradual decline in efficiency due to exposure to sunlight and weather. Most solar panels degrade at a rate of about 0.5% per year, meaning they still work well for many years. Quality of materials and installation practices greatly affect how quickly solar panels degrade.
Appropriate degradation rates of solar panels are estimated at 0.5% per year considering a well-maintained PV system featuring ideal conditions. However, solar panel degradation rates can reach up in some extreme cases, going as high as 1.4% or 1.54% per year.
