Semi-Analytical Electro-Thermal Modelling of a Photovoltaic Module for Evaluation of Spatial Temperature Distribution

The paper presents a two-dimensional thermal model coupled with the electrical model to investigate the performance of a PV module. An iterative procedure is implemented by calculating analytically the boundary conditions for each cell of the PV module placed in the environment, considering the effect of solar irradiance and Joule heating. The temperature distribution is then calculated in each cell using a numerical model where an accurate description of connections is included. The electric...

Experimental Evaluation of Energy Degradation of Photovoltaic Plants after 20+ Operation Years

In the context of the ever-growing importance of renewable energy sources, the long-term reliability assessment of PhotoVoltaic (PV) systems emerges as a critical aspect of ensuring sustainable energy production with cost-effective technologies. Nowadays, the first PV plants, installed at early 2000s, have achieved more than 20 years of operation: this reflects their predicted lifetime. Hence, evaluating their efficiency at the end of the estimated lifetime can provide important information r...

Comparative Analysis of Energy Yield between PERC and HJT Modules Tested in Experimental Campaigns Carried out in Northern Italy

The heterojunction (HJT) solar cells based on the integration of monocrystalline silicon and amorphous crystalline layers provide a remarkable improvement in terms of efficiency with respect to the Passivated Emitter and Rear Cell (PERC) modules, which are currently installed in most of plants. However, the efficiency gain in terms of energy production is not estimated by recent works in literature for the Mediterranean area: hence, this paper presents a comparative study of energy yield in T...

Comparison of Equivalent Circuit's Parameters Obtained for Half Cells of PV Mini-Modules Tested under Sunlight and Partial Shading

This paper aims is included in a line of research aiming to develop an automatic acquisition system for the fault detection in PV plants. The performance of photovoltaic (PV) generators can be modeled using electrical equivalent circuits with parameters ranging from three to seven. This study compares the equivalent circuits to extract the parameters for half-cells of PV modules tested under natural sunlight and partial shading. The tests, conducted at Politecnico di Torino (Italy), reveal th...

Experimental Analysis of Equivalent Circuit's Parameters for Half-Cell Photovoltaic Modules Under Natural Sunlight

In literature, the equivalent circuits of solar cells permit to approximate the electrical performance of PhotoVoltaic (PV) modules. This work is inserted in a research field aiming to develop a model for the automatic diagnosis of PV plants by their inverters based on the equivalent circuit's parameters. However, identical PV modules, generally, have slightly different electrical performance, and, hence, different equivalent circuit's parameters. Since the diagnostic model will need to take ...
