Description

Technical Field

[0001] The utility model relates to the technical field of solar photovoltaics, in particular to a connection structure of solar photovoltaic strings. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panels (modules), controllers and inverters. The main components are made of electrical components. Solar cells are packaged and protected after being connected in series to form large-area solar cell modules, which are then combined with power controllers and other components to form photovoltaic power generation devices. The main principle of photovoltaic power generation is the photoelectric effect of semiconductors. When photons shine on metals, their energy can be completely absorbed by an electron in the metal. The energy absorbed by the electrons is large enough to overcome the Coulomb force inside the metal atoms to do work, escape from the metal surface and become photoelectrons. When the P-type and N-type are combined together, an electric potential difference will be formed on the contact surface to become a solar cell.

[0003] Although the existing connection structure has the characteristics of good fixing effect and good anti-corrosion effect, the connection structure of the traditional solar photovoltaic string does not have the function of automatic adjustment, resulting in the solar photovoltaic group can only be fixed in one direction, so the utilization rate of sunlight is relatively low, unable to receive light all day long, resulting in limited resource utilization.
