The invention provides a photovoltaic assembly surface pollution degree determination device comprising the following units: a glass substrate attached to the photovoltaic assembly surface; a reactioncoating coated on one side of the glass substrate so as to form a structure laminating pollutants on one surface, wherein impedance changes can be formed through making contacts with the pollutants;a signal processor connected with the reaction coating so as to transmit impedance change signals, wherein the processor is used for calculating and processing the reaction coating signals, determining an impedance value variance according to the pollutant lamination impedance changes, and outputting a polluted/non-polluted determination signal. The photovoltaic assembly surface pollution degree determination device can sense the photovoltaic assembly surface impedance changes so as to effectively determine the assembly surface lamination pollution degrees, thus ensuring a proper washing period for the solar generating
