Abstract
The deployment of building integrated photovoltaics
in the urban environment represents an opportunity for
energy production and use at source. It also has a
positive impact on expanding the market for photovoltaics
resulting in reduction in cell and systems costs. An
example of such a system is the subject of this paper.
The operation of the photovoltaic facade installed at
Southampton University is constantly monitored. In
addition to system energy yields, the mismatch losses,
notably at low irradiance levels and during periods of
shading, were measured and evaluated. The
determination of the operational characteristic of each
string in the array is critical in identifying the interactions
that may occur between strings. and the resultant
degrading effect on system performance. The results
indicate that the original design configuration of the
strings of the array, determined as the optimal from
theoretical and conventional principles, is not the most
efficient. After optimisation of the connection
characteristics of the 24 strings in the array, an increase
of 8% in system efficiency was achieved.
