What is the energy efficiency of supercapacitor photovoltaic power generation of Mogadishu communication base station
A super capacitor consists of two metal plates on which the electrodes are deposited. These two electrodes are stacked together and separated by a membrane which serves, on the one hand, to isolate the two electrodes electrically, on the other hand, to drain the electrolyte. To have a simple model than the transmission line, while maintaining the validity of super capacitor electrical behavior, a three-branched model is proposed in. The parameters constituting the three-branch model are computed through an experimental full load of super capacitor with constant current. The load voltage is.
