Abstract

The invention discloses a device for efficiently heating a photovoltaic module. The device comprises a semiconductor heater and a control circuit. The semiconductor heater is used for locally and intensively heating the photovoltaic module, and the control circuit is used for controlling the starting and stopping of the semiconductor heater. The control circuit comprises a light sensation controller and a current detection controller which are connected in series, wherein the light sensation controller or the current detection controller is electrically connected with the semiconductor heater,and the light sensation controller is switched on in the presence of light, or otherwise, the light sensation controller is switched off; and the current detection controller is closed when detectingthat the generation current of the photovoltaic module is smaller than a set constant value, or otherwise, the current detection controller is opened. When the device works, the photovoltaic module is locally and intensively heated; the unheated module part becomes a thermal load due to no power generation capacity, the released heat can gradually melt ice and snow to enlarge the power generationarea and generate a positive feedback effect; and finally, the snow melting of the photovoltaic module can be realized automatically and quickly with high efficiency and at low cost and without manual intervention, and the power generation capacity can be recovered or improved.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a device for heating photovoltaic components with high efficiency. Background technique [0002] With the advantages of "huge reserves, convenient application, long-lasting supply, clean and harmless", solar energy has received more and more attention and favor, and has become one of the clean energy sources with the most development and utilization potential. With the continuous expansion of its application fields and the continuous maturity of industry technology, photovoltaic modules have been able to be applied in remote areas and even in harsh environments, which can provide great convenience for off-grid power supply and unattended operation. However, in the northern alpine region, it is inevitable that photovoltaic modules will be covered with snow and frost in winter, which will affect the working efficiency of photovoltaic modules. In severe cases, it may freeze an...
