Integrated photovoltaic module taking printed circuit board (PCB) as bottom plate

Abstract

The invention discloses an integrated photovoltaic module taking a printed circuit board (PCB) as a bottom plate. The integrated photovoltaic module comprises a PCB bottom plate, photovoltaic cell pieces, printed circuits, an inversion control circuit and two output sockets, wherein the printed circuits are arranged on a front surface of the PCB bottom plate and are used for connecting the photovoltaic cell pieces, a plurality of photovoltaic cell pieces are sequentially arranged on the front surface of the PCB bottom plate, positive leads and negative leads of all photovoltaic cell pieces arewelded on corresponding welding points on the printed circuits to form a photovoltaic cell string comprising the photovoltaic cell pieces, an output of the photovoltaic cell string is an output port,the inversion control circuit is printed at the top of a reverse surface of the PCB bottom plate, an input end of the inversion control circuit is connected with the output port, and an output end ofthe inversion control circuit is connected with the two output sockets. By the integrated photovoltaic module, the production efficiency and the product quality of the photovoltaic module are improved; and meanwhile, the photovoltaic cells and the inversion control circuit are integratedly designed, maximum power tracking of each photovoltaic module can be achieved, maximum energy utilization isachieved, and great convenience is brought to application.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to an integrated photovoltaic module with a PCB board as a base. Background technique [0002] Solar energy is an inexhaustible clean energy. In recent years, with the advancement of technology and the improvement of people's awareness of environmental protection, solar photovoltaic power generation has developed rapidly. [0003] At present, photovoltaic power generation systems are generally composed of photovoltaic cell module arrays, inverters, controllers, and batteries. After the photovoltaic cells form a square array, centralized control and inversion are performed. Due to the difference in power generation of each photovoltaic cell, this centralized control and inversion is not conducive to improving the efficiency of photovoltaic cells. [0004] At the same time, in the production of photovoltaic modules with traditional structures, it is necessary t...
