Research of volt-ampere characteristics testing method for photovoltaic cells Abstract:Volt-ampere characteristic(I-V) curve is one of the most important characteristics of solar arrays, and is an indispensable reference for field performance testing and designing of concentrating photovoltaic power generation system.
This paper introduces a diagnostic methodology for photovoltaic panels using I-V curves, enhanced by new techniques combining optimization and classification-based artificial intelligence. The research is organized into two key sections.
Electrical characterization of a PV panel is attained by measuring the I-V characteristics of field-aged modules and comparing them to the module's initial measured I-V characteristics before deployment in the field. Thus, any electrical properties variations are recorded to study PV panel performance .
Figure 1. Classification of photovoltaic technologies [18, 19, 20, 21]. The PV characteristic curve, which is widely known as the I–V curve, is the representation of the electrical behavior describing a solar cell, PV module, PV panel, or an array under different ambient conditions, which are usually provided in a typical manufacturer's datasheet.
The most widely used method of modeling the performance of a solar cell/panel (based on its I-V curve, where I is the output current and V the output voltage) is an equivalent circuit based on one current source, one
This paper introduces a diagnostic methodology for photovoltaic panels using I-V curves, enhanced by new techniques combining optimization and classification-based artificial intelligence.
