Photovoltaic module not shielded by front frame

Abstract

The invention relates to a photovoltaic module without front side frame shielding, and the module comprises a glass mechanism which comprises a step-shaped front side mechanism facing the sun; the step-shaped front surface mechanism comprises a first front surface and a second front surface, and the second front surface is arranged on the periphery of the first front surface and is shorter than the first front surface; the mounting assembly comprises two mounting frames which are horizontally arranged; a U-shaped clamping frame is arranged at the top of the mounting frame and is used for clamping the peripheral part of the step-shaped front mechanism; the inner wall of the U-shaped clamping frame abuts against the second front face, and the top face of the U-shaped clamping frame does not exceed the first front face. Through the arrangement, the problem that the whole solar cell module is damaged due to a serious hot spot effect caused by the fact that accumulated dust is left and the module is shielded due to the specific frame design on the front side of the existing photovoltaic module can be solved.

Description

technical field [0001] The invention relates to the technical field of crystalline silicon solar modules, in particular to a photovoltaic module without front frame shielding. Background technique [0002] Due to the unique frame design of photovoltaic modules, a lot of dust will remain under many installed modules / cause local shadows, which will cause the "hot spot" phenomenon of some batteries heating. [0003] If the effect of dust is not eliminated and exists for a long time, when the hot spot effect reaches a certain level, the solder joints on the components will melt and destroy the grid lines, which will lead to the scrapping of the entire solar cell component. [0004] It can be seen that the above shielding phenomenon seriously affects the service life of the junction box and the battery board. Among them, due to the accumulated dirt on the panel surface, the battery efficiency loss may reach more than 15%; the annual average power generation efficiency may decrea...
