Of course, the storage battery may not be provided, so that the power generated by the power generation unit 2 is connected to the grid, and the electric energy required by the heat generation unit 3 may be provided by the commercial power. Under the condition that the photovoltaic module can not generate power due to the fact that the ice and snow cover in winter, the commercial power can be used for supplying power and heating the heating unit 3 for a short time to melt the ice and snow. Since the ice and snow can be melted only at a temperature of 0 ℃ or more, the amount of electricity used by the heat generating unit 3 is small and the time is short. In some embodiments, the heat generating unit 3 may be powered by a voltage of 12-380 v.
In one embodiment of the present invention, the photovoltaic module body 20 further comprises: a decorative layer 4;
the decorative layer 4 is provided on the outer surface of the glass layer 1 near the heat generating unit 3.

In some embodiments, the decorative layer 4 can be made by high-temperature digital printing, and then sintered on the outer surface of the glass layer 1 by a toughening furnace at high temperature, and is completely free from problems when used in outdoor environment.
