Input data requirements for performance modelling and monitoring of photovoltaic plants

Publikation: Bidrag til tidsskriftTidsskriftartikel

Abstract

This work investigates the input data requirements in the context of performance modeling of thin-film photovoltaic (PV) systems. The analysis focuses on the PVWatts performance model, well suited for on-line performance monitoring of PV strings, due to its low number of parameters and high accuracy. The work aims to identify the minimum amount of input data required for parameterizing an accurate model of the PV plant.

The analysis was carried out for both amorphous silicon (a-Si) and cadmium telluride (CdTe), using crystalline silicon (c-Si) as a base for comparison. In the studied cases, modelling the performance of the PV modules at high irradiances requires a dataset of only a few hundred samples in order to obtain a power estimation accuracy of ~1-2\%.
