Low-IAM-loss and high-generating-capacity assembly

Abstract

The invention relates to a low-IAM-loss and high-generating-capacity assembly. The assembly comprises a photovoltaic assembly obliquely installed on an installation surface, the photovoltaic assemblycomprises upper glass, a pattern structure is arranged on the upper glass, an acute included angle formed by the pattern structure and the horizontal plane of the photovoltaic assembly is alpha, and an included angle formed by the photovoltaic assembly and the installation surface is beta, when beta is 0 to 80 degrees, the included angle alpha between the pattern structure and the horizontal planeis 20 to 35 degrees, and when beta is 80 to 90 degrees, the included angle alpha between the pattern structure and the horizontal plane is 30 to 60 degrees. The optimal IAM is obtained by designing the angles of different glass patterns according to different angle mounting modes, the power generation capacity of the assembly can be improved, dust accumulation can be prevented, special patterns are arranged on the surface of the upper glass, and accumulated dust falls onto the installation surface along the patterns along with rainwater and does not stay on the surface of the photovoltaic assembly in rainy days; and meanwhile, the anti-dazzle effect can be achieved by reducing reflected light.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a component with low IAM loss and high power generation. Background technique [0002] Photovoltaic modules are an important component of photovoltaic power plants. The more fully the use of light by photovoltaic modules, the higher the power generation. Improving the utilization of light is a way to increase the power generation of photovoltaic modules. The light can reach the surface of the cell after being incident on the glass and film from the air. This process is that the light enters the optically denser medium from the optically sparse medium. In this case, the transmittance and reflectance of light vary with the incident angle. When the angle of incidence is 0 (vertical incidence), the transmittance of light is the largest and the reflectance is the lowest; and as the angle of incidence gradually increases, the transmittance of light gradually decreases and the ref...
