Problems solved by technology
see Figure 1A In the current series system, the cables connected to the components on both sides are directly connected to the terminals on the combiner box through connectors. In this case, more connectors and cables are used. In addition, multiple terminals need to be installed on the combiner box, and the volume of the combiner box will also increase; these will increase the cost, and the cleanliness of the system will also be affected due to more wiring

The invention brings forward a photovoltaic component branch connector and a component series system utilizing the photovoltaic component branch connector. The series system comprises a plurality of photovoltaic components arranged on both sides of a cable collecting area; positive and negative electrodes of adjacent photovoltaic components on the both sides are separately connected in series with adapters through cables; the positive and negative electrode connecting cables on the both sides are connected to the cable collecting area through a plurality of connectors; the negative electrode connecting cables on the both sides are connected to a negative electrode branch connector; and the positive electrode connecting cables on the both sides are connected to a positive electrode branch connector; and the negative electrode branch connector and the positive electrode branch connector are connected to a combiner box. According to the photovoltaic component series system, the cables are collected through the branch connectors in the cable collecting area and connected to the combiner box. The component series system are simple in routing, and the usage of the cables and connectors is reduced. Meanwhile, the size of the combiner box is reduced. The cost of the component series system and a whole photovoltaic power generation system is reduced. Furthermore, the component series system is high in safety degree.
Description
technical field [0001] The invention relates to the technical field of solar photovoltaic, in particular to a branch connector for photovoltaic components and a component series system using the same. Background technique [0002] With the global climate change and the increasingly severe environmental pollution caused by traditional fossil energy, the green renewable energy industry has received more and more attention and rapid development. Solar energy is a renewable resource, and solar cell technology that utilizes the photovoltaic effect to generate electricity has attracted worldwide attention. Solar cells are made of materials that can produce photovoltaic effects, such as silicon, gallium arsenide, indium selenide copper and other materials, which can convert light energy into electricity. At present, photovoltaic modules composed of multiple solar cells are widely used to build various photovoltaic power generation systems, or used as building curtain walls to buil...
