TESTING SYSTEM FOR SOLAR CELL

摘要

PURPOSE: A solar cell demonstrating system can easily draw the best circuit structure for a certain solar cell. CONSTITUTION: An environment detecting sensor senses and transmits the temperature of solar cell and the minimum solar radiation quantity. A relay multiplexor connects the output terminal of an input channel first relay to load. A voltage current detector having a first input and a second input terminal connected to a first output and a second output channel respectively detects current and voltage values of a solar cell applied according to switching of a controller and measures the current-voltage characteristic curve. The load is connected to the second output terminal of the first relay and consumes electric power produced by the solar cell. A computer monitors and analyzes data extracted by the environment detecting sensor and the voltage current detector.
