The dependence of PR<1 and A<1 on PV system life cycle cost (LCC) and on design decisions is explored. Here we differentiate between the effects of PR, which is defined as a reduction in the instantaneous efficiency of the system, and Availability, which quantifies time that the plant is in service.
An overview of potential module failures, influencing factors and effects can be found in a previous report of IEA PVPS Task 13 . End-of-life is defined differently for PV modules, depending on the specific context or issue. The end-of-life is typically dependent on the use of the PV module and the specific conditions of the PV power plant.
To evaluate and predict the service lifetime of PV modules in real-world operating conditions, mathematical approaches are usually utilized , , . Physical and statistical methods have been commonly used and recently machine learning approaches are being applied.
The latest scientific work shows that service lifetime and degradation models for PV modules are of specific use if they combine different modelling approaches and include know-how and modelling parameters of the most relevant degradation effects.
The IEA Photovoltaic Power Systems Programme (IEA PVPS) is one of the TCP’s within the IEA and was established in 1993. The mission of the programme is to “enhance the international collaborative efforts which facilitate the role of photovoltaic solar energy as a cornerstone in the transition to sustainable energy systems.”
The lifetime of PV systems is difficult to quantify because most introduced systems are still in operation or were produced in the early stages of the technology’s development. However, studies on the life expectancy of PV systems have been conducted, and the results are outlined in Table 1.
