At the same time, the geothermal source integrated system 47 reduces a lot of energy consumption for the deicing and snow removal system; while deicing and snow removal of the photovoltaic panel 29, it can also realize the trigeneration of cold, heat and electricity. In this way, the present invention has three working modes, corresponding to severe, moderate and slight snow accumulation conditions respectively; through the integration of the Kanot battery system and the supercritical CO2-ORC system, it is possible to provide heat source and power supply for snow removal of photovoltaic panels without consuming additional external energy, and with the cooperation of the Kanot battery heating network pipeline and the electric heating network, snow removal blades and snow removal brushes, the photovoltaic panels can be deeply and efficiently de-iced and de-snowed.
