Improving the prediction of photovoltaic power production in urban environments

This paper proposes an improved model to estimate the power and energy production from photovoltaic installations under dynamic shading conditions typical of urban environments. The impact of dynamic shades on the power production is analyzed, illustrating the large errors introduced by classical prediction approaches. Moreover, a procedure to model the shades profile in any environment is described and illustrated. Finally, an experimental irradiance profile is used to evaluate the performance of the proposed model in contrast with the classical approach, obtaining satisfactory results.
