Comparative Reliability Analysis of PV Modules under tropical conditions

The lifetime of PV modules is reduced due to a variety of degradation modes. Failure modes that contribute significantly to PV module output power losses include snail trails, hotspots, micro cracks, bubbles or delamination, and dust accumulation. The correlations between these phenomena, like those between corrosive environment and potential-induced breakdown, are not well understood. As a result, in this review, we will try to explain the relationship between snail trails, hotspots, microcracks, bubbles or delamination, and dust accumulation on photovoltaic module components in order to ensure the PV modules' reliability. This paper in the Photovoltaic literature gives an overview of several Maximum Point Tracking (MPPT) techniques that have been recently designed, simulated and/or experimentally validated. The main objective of every MPPT technology is to maximize the output of a photovoltaic array with shade or unshade conditions. The characteristics presented in this paper are unique, and they provide researchers with a starting point for choosing and implementing an appropriate MPPT technique.

Photovoltaic (PV) modules are generally considered to be the most reliable components of PV systems. The PV module has a high probability of being able to perform adequately for 30 years under typical operating conditions. In order to evaluate the long-term performance of a PV module under diversified terrestrial conditions, outdoor-performance data should be used. However, this requires a wait of 25 years to determine the module reliability, which is highly undesirable. Thus, accelerated-stress tests performed in the laboratory by mimicking different field conditions are important for understanding the performance of a PV module. In this paper, we discuss PV-module degradation types and different accelerated-stress types that are used to evaluate the PV-module reliability and durability for life expectancy before using them in the real field. Finally, prevention and correction measures are described to minimize economic losses.
