Description

technical field [0001] The present application relates to the field of photovoltaic technology, in particular to an ultra-densely arranged photovoltaic module. Background technique [0002] With the increasing shortage of energy, photovoltaic technology, as a technology that can directly convert sunlight energy into electrical energy, has been widely used. The structural design of photovoltaic modules directly affects the power generation efficiency of photovoltaic modules. [0003] In the prior art, there are relatively large gaps in the arrangement of cells in the photovoltaic module, which leads to a low space utilization rate of the module, which in turn leads to a low power generation efficiency per unit area. In addition, the cells in the existing photovoltaic modules are integrally welded, and the current of the cells is relatively large, resulting in large internal friction of the components and low power generation efficiency. In addition, the internal circuit s...

Problems solved by technology

[0003] In the prior art, the gaps in the arrangement of the cells in the photovoltaic module are relatively large, resulting in a low space utilization rate of the module, which in turn leads to a low power generation efficiency per unit area

In addition, the cells in the existing photovoltaic modules are welded as a whole, and the current of the cells is relatively large, resulting in large internal friction of the components and low power generation efficiency

In addition, the internal circuit structure of existing modules is mostly a series structure composed of multiple cells. When a cell operates abnormally (such as being blocked by foreign objects such as leaves and bird droppings), the power generation efficiency of the entire module will decrease, resulting in Big waste of resources

[0004] There are at least the following problems in the prior art: the gaps in the arrangement of the cells in the existing photovoltaic modules are relatively large, resulting in low space utilization of the components, the cells are welded as a whole, and the current of the cells is large, resulting in The internal friction is relatively large, and the internal circuit structure of the existing modules is mostly a series structure composed of multiple cells. When a cell operates abnormally (such as being blocked by foreign objects such as leaves and bird droppings), the power generation efficiency of the entire module will decrease. All of these lead to low power generation efficiency of existing photovoltaic modules
