Abstract
A testing method of a solar cell panel of the present invention, includes steps of: (a) providing an ambient light with steady illumination to the surface of a solar cell panel to introduce a steady signal to its electrical output; (b) providing a modulation light to a given area of the solar cell panel to introduce a modulated signal to its electrical output corresponding to the given area; and (c) analyzing electrical output of the solar cell panel to obtain electrical properties corresponding to the given area. The testing method can test the solar cell panel efficiently, detect and locate defects accurately so that the defects can be corrected and feed back to improve manufacturing process.
