What is it about?
In photovoltaic systems, partial shading is a problem that causes losses. Interconnectivity with related systems is a feature that does not appear in many models. The computational weight is significant because the correct simulation of a model depends on it. These three factors are considered in the model presented in this paper: Partial shading, interconnectivity, and computational lightness.

Why is it important?
This paper shows that the capacity of interconnection and modularity can be preserved in photovoltaic systems to perform flexible modeling of photovoltaic arrays in conjunction with related systems, e. g. MPPT, power converters, electrical grid, loads, other sources, etc. The paper also shows the ability of the proposed method to deal with the problem of partial shading.
Perspectives
We hope that the article will get attention towards the area of modeling of photovoltaic systems through Bond Graphs. We would particularly like to point out the feasibility in computational terms of the proposed model, as well as its modularity, which allows two things: interconnection with related systems and the study of the phenomenon of partial shading.
