Experimental Analysis of a Developed I-V Curve Tracer under Partially Shading Conditions

Photovoltaic technologies stand out for their reliability and durability. However, in order to verify the perfect conditions of a PV installation, it is necessary to carry out the commissioning process. One of the most important equipment for the commissioning process is the I-V trace curve. The I-V trace curve has a high cost, making it difficult for small installers of PV systems. At this point, the paper presents an I-V curve trace solution, with low cost and high precision. In order to do so, an I-V curve trace was designed and tested in situations of partial shading that generate curves of more difficult tracing. As a result, it was able to obtain values close to high-cost commercial equipment. Therefore, the developed I-V curve trace can be a solution for small PV system installers.
