In order to determine the prospects of the use of solar panels as a basis for the creation of the charger, you must know the several parameters: short circuit current, open circuit voltage, coefficient of efficiency and others. In this paper, these parameters are measured based on the results of research the current-voltage characteristics of the solar panels, resulting in an automatic mode with the use of a computer and a digital meter E7-20.

Keywords: Solar cell, solar panel, solar battery, power source, charger, current-voltage characteristic, coefficient of efficiency, LCR meter
