An Alternative Image Analysis Method for Parameter Extraction of Solar Cells and Panels

This article proposes a method that utilizes image analysis for the extraction of parameters in solar cells and panels. The method leverages the I-V curve image, provided by the manufacturer in the device's datasheet (solar cell/panel), which is processed using image editing software (Adobe Photoshop). Using Matlab, a reference system is established, enabling the calculation of key pa-rameters such as series resistance, shunt resistance, and maximum power point of the solar device. In this way, this method eliminates the need for formulating complex systems of equations, conducting prior measurements, employing costly equipment, or acquiring a dataset, as is the case with other parameter extraction methods for solar devices.
