The implementation of diffuse radiation shading computation in ESP-r

Joe Clarke, Nova Scotia

Abstract: Approaches to the modelling of irradiance and illuminance distribution within the ESP-r system, based on direct computation and cooperating programs respectively, are summarised. A recent extension to the projection-based, solar shading algorithm of the former approachaddressing 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.
