Abstract—This paper presents the capacitance effect on the output characteristics of solar cells (SCs). For this purpose, a current sweep circuit was built to bias the SC. We show that the output characteristics begin to split due to charge or discharge of the internal. . High efficiency modules have high capacitance which can cause errors when measuring I-V curves, if not measured properly. The capacitance can also cause a large in-rush current which can pose challenges for curve tracers being able to measure at all. Experimental. . High efficiency (HE) solar modules can store significant electronic energy as excess charge i.e. capacitance. This charge is released instantaneously, as an inrush current when the module string is “shorted” during field testing. The capacitance can even cause measurement errors, when it is not.
