The implementation of diffuse radiation shading computation in ESP-r

Research output: Contribution to conferencePaperpeer-review


Approaches to the modelling of irradiance and illuminance distribution
within the ESP-r system, based on direct computation and co-operating
programs respectively, are summarised. A recent extension to the
projection-based, solar shading algorithm of the former approach –
addressing diffuse beam shading quantification under realistic sky
conditions – is described. The paper concludes with results from an
example application of the extended algorithm to investigate the impact of
diffuse shading on photovoltaic component power output.
