Problems solved by technology
In the prior art, the photovoltaic modules are connected to form an array through the terminals led out of the junction box. The junction boxes are all split, the material cost is high, and the photovoltaic resistance loss is high. In addition, the junction box needs to open holes on the back plate to lead out the electrodes, and the process is complicated. , High production cost, inconvenient connection between photovoltaic modules and troublesome operation

The invention relates to a novel photovoltaic module connected through magnetic attraction. The photovoltaic module comprises a photovoltaic cell string, an EVA layer, a protection panel, a backboardand a magnetic attraction connecting piece. The photovoltaic cell string, the EVA layer, the protection panel and the backboard form a photovoltaic power generation panel. The photovoltaic cell stringis formed by connecting a plurality of cells and copper wires in series / in parallel. The magnetic attraction connecting piece comprises a plurality of first magnetic attraction connectors and a plurality of second magnetic attraction connectors, the first magnetic attraction connectors are arc-shaped protrusions, the second magnetic attraction connectors are arc-shaped recesses, and the first magnetic attraction connectors and the second magnetic attraction connectors are matched in shape and are in magnetic conductive connection with each other. Adjacent photovoltaic power generation panelsare connected in a magnetic attraction connection mode, so components such as a junction box and a wiring terminal are omitted, material cost and photovoltaic resistance loss are reduced, holes do notneed to be formed in the back plate, the process is simpler, production cost is lower, wiring and wire disassembly are avoided during disassembly and assembly, operation is simpler and more convenient, and connection between adjacent photovoltaic power generation panels is firmer under the action of magnetic force.
Description
technical field [0001] The invention relates to the technical field of solar photovoltaics, in particular to a novel photovoltaic module connected by magnetic attraction. Background technique [0002] Due to the increasing scarcity of fossil energy and the deterioration of the ecological environment, the society's demand for renewable and clean energy is increasing. Due to its unique cleanliness and renewability, solar energy has enabled the rapid development of photovoltaic power generation, a renewable clean energy technology. Photovoltaic power generation panels are devices that use photovoltaic power generation technology to convert solar energy into electrical energy. They are generally composed of protective panels, EVA layers, photovoltaic cell strings, backplanes, junction boxes, and aluminum alloy frames. Due to the heavy weight and high cost of aluminum alloy frames , and it is easy to be struck by lightning, so a frameless photovoltaic module has gradually emerge...
