Method and device for measuring current voltage Method and device for measuring current voltage characteristics of solar panels Ingredient characteristics of solar panels

摘要

The invention relates to a method and apparatus for measuring the current-voltage characteristic curve of a solar panel (1). According to the method, a light pulse (12, 13) is applied to the solar panel (1), and the response (14, 15) of the solar panel to the light pulse is measured by varying the electrical load (5) connected to the output of the solar panel. According to the method, the measurement is carried out with the help of a short-duration decaying light pulse (12) such that the falling tail (13) of the pulse is used for such a short period that the intensity of the pulse (10) does not have time to change essentially during the measurement.
