Photovoltaic energy occupies a significant place in the renewable energy
market, with photovoltaic (PV) modules playing a vital role in converting solar
energy into electricity. However, their effectiveness is likely to be affected
by variations in environmental conditions, including temperature and relative
humidity. The study examines the impact of these major climatic factors on
the reliability of PV modules, aiming to provide crucial information for optimizing
and managing these systems under varying conditions. Inspired by
Weibull’s law to model the lifespan of components, we proposed a mathematical
model integrating a correction factor linked to temperature and relative
humidity. Using this approach, simulations in Matlab Simulink reveal
that increasing temperature and relative humidity have an adverse impact on
the reliability and lifespan of PV modules, with a more pronounced impact
on temperature. The results highlight the importance of considering these
environmental parameters in the management and optimization of photovoltaic
systems to ensure their long-term efficiency.
