PV module degradation mechanisms under different environmental stress factors
conference contribution
posted on 2013-11-07, 09:54 authored by Dan Wu, Jiang Zhu, Tom BettsTom Betts, Ralph GottschalgUnderstanding the degradation behaviours of
photovoltaic (PV) devices is critical for
optimising its financial viability. The degradation
of PV modules is dependent on multiple factors
such as installation site, mounting conditions,
manufacturing process and module types. This
means that in order to understand the long term
behaviour of PV modules, one needs to assess
the stresses acting on the modules (first two
factors) and the module’s response to these. In
this paper, the possible degradation
mechanisms within a PV module according to
different stress factors are discussed and linked
to typical module constructions. The
relationships between degradation mechanisms
and electrical performance are analysed as a
first step to predict long term power degradation.
