Abstract

The invention provides a photovoltaic assembly with a lightning-protection device, comprising a discharge tube, wherein one end of the discharge tube is electrically connected with the output end of the photovoltaic assembly, and the other end of the discharge tube is connected to the ground. Thus the photovoltaic assembly can effectively prevent the damage of thunder and lightning. In the optimal scheme, the photovoltaic assembly also comprises a voltage dependent resistor, and the voltage dependent resistor is electrically connected between the discharge tube and the output end of the photovoltaic assembly and connected in series with the discharge tube. Thus the service life of the discharge tube and the voltage dependent resistor can be effectively prolonged.

Description

technical field [0001] The invention relates to the field of new energy, and in particular to a photovoltaic module with a lightning protection device. Background technique [0002] With the continuous progress of human civilization, the consumption of energy in the world is becoming more and more serious. With the outbreak of the energy crisis in recent years, the development and utilization of new energy has become an important part of social development and progress.
