This research investigates the effects that electrical mismatches and partial shading can have on the performance of photovoltaic arrays. The analysis adopts a probabilistic point of view where the most relevant parameters of the solar units are seen as random variables. The analysis relies on an efficient and robust simulation technique, based on Wave Digital principles, that is tailored to the modular topology of solar arrays. It is shown how electrical mismatch, solar shading and array topology can interact among them in a quite complex way.

Abstract
This research investigates the effects that electrical mismatches and partial shading can have on the performance of photovoltaic arrays. The analysis adopts a probabilistic point of view where the most relevant parameters of the solar units are seen as random variables. The analysis relies on an efficient and robust simulation technique, based on Wave Digital principles, that is tailored to the modular topology of solar arrays. It is shown how electrical mismatch, solar shading and array topology can interact among them in a quite complex way.File in questo prodotto:
