The invention provides a screen plate of a solar panel. The screen plate comprises a screen frame, stainless steel screen cloth and a pattern, wherein the stainless steel screen cloth is made by arranging a plurality of stainless steel screen wires vertically and horizontally; the edges of the stainless steel screen cloth are fixed in the screen frame; the screen frame is provided with at least two groups of detection ends; the two groups of detection ends are (A1, A2) and (B1, B2); screen wire endpoints on the four edges of the screen cloth are fixedly connected to four leads respectively; A1 and A2 are positioned on one group of opposite edges of the screen cloth, and are connected with the two leads on the opposite edges respectively; B1 and B2 are positioned on the other group of opposite edges of the screen cloth, and are connected with the two leads on the opposite edges respectively. In the screen plate of the solar panel provided by the invention, the screen plate is provided with the detection ends which are used for detecting resistance of the screen plate in order to judge the problems of screen plate deformation, wire breaking, damage and the like, so that the performance testing of the screen plate becomes easier and rapider on the premise of not influencing a screen plate structure.
