Automatic snow removal device for solar module and control method thereof

Abstract

The invention relates to an automatic snow removal device for a solar module and a control method thereof. The device comprises an electric heating film; and the electric heating film is attached onto a back plate of the solar module. The electric heating film is connected with the module; an electronic switch is connected between the electric heating film and the module in series; a storage battery pack with a control switch is connected between a module string formed by the module and an inverter in parallel; the control switch and the electronic switch are in control connection with a control transmitter respectively; and the control transmitter is connected with an Ethernet. During the snowing or freezing time period, the control transmitter transmits a wireless signal to each wireless electronic switch, a circuit between the module and the electric heating film is switched on, and the electric heating film starts heating; and when the solar radiation is lower or at night, the control transmitter transmits a control signal to the storage battery pack, and the storage battery pack supplies the power for the electric heating film by utilizing the circuit of the module self. The invention has the beneficial effects that accumulated snow and frozen matters on the surface of the module can be effectively removed; the adaptability of the module in severely-cold areas and in icy and snowy areas can be improved; and the power generation efficiency can be improved.

Description

technical field [0001] The invention relates to an automatic snow removal device for solar modules and a control method thereof. Background technique [0002] As human beings pay more attention to the development and application of new energy, and increase capital investment, the solar photovoltaic industry has also developed vigorously, and the application field of solar photovoltaic has become wider and wider. However, in some severe cold and remote areas, due to the frequent hazards of ice and snow, under the condition of ice and snow cover, the power generation performance of the components will be reduced, and the support system will bear severe ice and snow loads. [0003] However, there is no good way to remove ice and snow in the industry. For light snow, it usually uses its own inclination and solar radiation to melt and eliminate it, which seriously affects the power generation performance of the photovoltaic system. For severe snow, it is usually manually removed,...

[0003] However, there is no good way to remove ice and snow in the industry. For light snow, it usually uses its own inclination and solar radiation to melt and eliminate it, which seriously affects the power generation performance of the photovoltaic system. For severe snow, it is usually manually removed, which is time-consuming and laborious. It is even more difficult to remove snow in remote areas like BIPV or alpine
