However, there are some challenges concerning the durability of photovoltaic modules that need to be overcome. Several factors lead to its degradation with a progressive reduction in its efficiency over the years. This aging depends on the type of photovoltaic technology and on the environment where the modules are installed.
Solar panels are generally very durable. Most solar panels are designed and tested to withstand the elements like hail, high winds, and heavy snow loads. And thanks to their lack of moving parts, solar panel systems usually require little to no maintenance. Still, maintaining your solar panels can boost production.
Manufacturers of solar photovoltaic modules usually guarantee the life span for more than 20 years. It is therefore necessary to track and mitigate degradation of PV modules over this period to satisfy such guarantees and beyond this period to identify maintenance and repair requirements.
These panels are designed with degradation in mind; manufacturers often provide a limited power warranty of 25 years, guaranteeing that the panels will maintain at least 80% of their output capacity for the duration of this period. Some solar panels even exceed this expectation, maintaining efficiency levels higher than 80% past their 25-year mark.
Here are some factors that affect the life expectancy of solar panels: The quality of the solar panels themselves is a vital factor that influences their longevity. High-quality panels, manufactured with stringent quality control and premium materials, are less susceptible to degradation over time.
Photovoltaic cells degradation is the progressive deterioration of its physical characteristics, which is reflected in an output power decrease over the years. Consequently, the photovoltaic module continues to convert solar energy into electrical energy although with reduced efficiency ceasing to operate in its optimum conditions.
