Embodiment Construction

[0013] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0014] like figure 1 , 2 As shown, it is the most preferred embodiment of the present invention, including a light-transmitting glass substrate 1, a solar cell array and a backplane composed of solar cells 2 at predetermined intervals, and the solar cell array is sealed on the glass substrate 1 by a resin material. and the backplane, the adjacent solar cells 2 in each column are electrically connected by leads 3, the solar cells 2 in each column are connected in series, and the output terminals of the solar cells 2 in each column are connected with patch diodes 4 . The polarity of the chip diode 4 is electrically reversed to the output end of each row of so...

Abstract

The invention relates to the technical field of photovoltaic components and particularly relates to a solar energy component internally provided with a diode. The solar energy component comprises a nonopaque glass substrate, solar cell slice arrays and a rear panel, wherein the solar cell slice arrays are composed of solar cell slices and sealed between the glass substrate and the rear panel through a resin material, adjacent solar cell slices in each column are electrically connected through leading wires, each column of the solar cell slices are in a series connection, and a patch-type diode is connected between output ends of the solar cell slices in each column. The solar energy component has the advantages that by means of the patch-type diode, the diode is installed in the component, sizes of the solar energy component and a connecting box are reduced, the solar energy component is convenient to stack and transport, the production and material costs are low.

Description

technical field [0001] The invention relates to the technical field of photovoltaic modules, in particular to a solar module with built-in diodes. Background technique [0002] Solar cell modules, also called solar panels, are the core part of the solar power generation system and the most valuable part of the solar power generation system. Its function is to convert the solar energy into electrical energy, or store it into the battery, or promote work load. The diode in the solar cell module can conduct the voltage, which is very beneficial to increase the output power of the photovoltaic module. [0003] In existing solar cell modules, the connecting wires are led into the junction box on the back of the solar cell panel, and diodes are installed between the wires to prevent current kickback. This makes the back of the solar cell panel protrude, the appearance is not beautiful enough, the volume is large, and the cost is high. Contents of the invention [0004] The te...
