TRANSIENT PROCESS OF A SOLAR PANEL AS THE BASIS OF A DYNAMIC METHOD FOR MEASURING ITS ELECTRICAL PARAMETERS AND CHARACTERISTICS

Abstract

The use of solar energy in measurement technologies encourages the search for original circuit solutions. An example of this is the use of the Mendocino motor, a feature of which is levitation magnetic suspension and commutation of the rotor windings based on periodic changes in the illumination of solar panels located directly on the rotor itself. Analysis of the transient process of a solar panel provides the ability to measure the series resistance of a solar panel. This method is an alternative to the measurement method based on obtaining several current-voltage characteristics at different illumination. The development of a dynamic method for measuring the electrical parameters and characteristics of solar panels received a significant and essential boost with the creation of a means of their non-contact measurement.The transient process of a solar panel is the basis for a dynamic method of measuring its electrical parameters and characteristics. In particular, the period of free oscillations in the current sweep circuit in the initial phase of the short-circuit mode measures the electrical capacitance of the solar panel, and the decay decrement measures its series resistance.
