Performance characterisation of photovoltaic modules
conference contribution
posted on 2011-02-03, 09:42 authored by Ralph GottschalgA review of the performance characterization of
photovoltaic modules is given, that charts the progress
made in the European research project ‘PV-Performance’
as well as other work carried out in Europe. The aim is to
illustrate the measurement and prediction accuracy of
energy delivery. It is shown that direct inter-comparisons
of PV modules may have as much as 6.5% uncertainty in
the comparability between modules and that any
difference much lower than this is not a meaningful
conclusion. A significant contribution to this is the
determination of the rated power of the modules chosen
for the inter-comparison and the lack of statistical
numbers. The rated power is also important in the context
of modeling the performance and thus must be as
accurately as somewhat possible. It is shown that the
uncertainties of the calibration laboratories are not borne
out by round robin inter-comparisons and further work is
needed in this field. Uncertainties for wafer-based devices
are shown to be in a range of ±3%, while different thin film
technologies may have higher uncertainties. It is shown
that even simple modeling approaches are good enough
to predict PV performance to within the measurement
accuracy of most datasets.
