The application of distributed modelling technique is becoming popular in characterisation of photovoltaic (PV) modules for its ability to investigate localised behaviour. A PV module is a 3D device in which there may be considerable inhomogeneities that can cause spatially non-uniform performances and hence, mismatches. Consequently, a distributed model containing the spatial information is required to accurately describe the performance of modules. This work presents a flexible, distributed network simulation engine that introduces a hierarchical architecture and a PV-oriented nodal analysis method. The module is split down to sub-cells, enabling the spatially-resolved and quantitatively analysis of electrical properties such as current generation or absorption, operating voltage, series resistance, shunt resistance, etc. It shows that this distributed network modelling approach is a promising tool in the characterisation of PV modules.
