Actual PV module performance including spectral losses in the UK
conference contribution
posted on 2011-03-11, 12:28 authored by Sheryl WilliamsSheryl Williams, Tom BettsTom Betts, Pongpan Vorasayan, Ralph Gottschalg, David InfieldSTC efficiencies are not sufficient to compare
photovoltaic devices of different semiconductor material
or device configurations. The energy yietd will change as
the variables of STC deviates from their original values
when the modules are placed in various climatic
conditions. The magnitude of this change for different
modules is not always clear and needs to be
investigated and modelled.
A modeling and analysis method named site
specific conditions (SSC) is demonstrated which is a
measurecorrelatepredict approach. It allows an
accurate estimation of the actual energy yietd for
different sites based on the measurements at one single
site. The method takes into account the effect of the
physical operating environment and translates this to
other meteorological conditions on the basis of physics
related formulae, Our results show a large seasonal
variation for modules for the different effects. For
crystalline modules losses of up to 12% in the summer is
due to the temperature effect while the multi-junction thin
film losses of more than 30% in the winter is due to
spectral changes and incidence angle effect for the UK.
