Design and Simulation of Photovoltaic Array
Asian Journal of Electrical Sciences, 2019This paper illustrates a simple yet accurate method of modelling photovoltaic array. By adjusting the curve at three points: open circuit, maximum power, and short circuit, the parameter of the nonlinear equation can be determined. The information about these three major points is provided by all commercial array datasheets, using this data we can ...

Design optimization of photovoltaic arrays on curved surfaces
2018 Design, Automation & Test in Europe Conference & Exhibition (DATE), 2018Flexible photovoltaic (PV) arrays often have to be mounted on surfaces that have a significant amount of curvature. These include solar-powered vehicles, planes, and also some wearable devices. However, this inevitably leads to non-uniform solar irradiance among connected PV cells.

Self-Cleaning Microcavity Array for Photovoltaic Modules
ACS Applied Materials & Interfaces, 2018Development of self-cleaning coatings is of great interest for the photovoltaic (PV) industry, as soiling of the modules can significantly reduce their electrical output and increase operational costs. We fabricated flexible polymeric films with novel disordered microcavity array (MCA) topography from fluorinated ethylene propylene (FEP) by hot ...

About the criteria for triggering the reconfiguration of a photovoltaic array
2014 IEEE 23rd International Symposium on Industrial Electronics (ISIE), 2014The dynamical reconfiguration of the photovoltaic array is a feasible method for maximizing the electrical power it produces in presence of partial shading. Although in literature some algorithms aimed at determining the best configuration to be settled for a given shadowing pattern have been presented, no indications about the electrical conditions ...

Photovoltaic array loss mechanisms
Solar Cells, 1986Loss mechanisms which come into play when solar cell modules are mounted in arrays are identified. Losses can occur either from a reduction in the array electrical performance or with nonoptimal extraction of power from the array. Electrical performance degradation is caused by electrical mismatch, transmission losses from cell surface soiling and ...
