Abstract

A novel concave component is composed of an inner component and an aluminum frame, wherein the inner component is a double-wave component composed of the following materials arranged in sequence: front glass, packaging material, a solar cell, back panel glass and a junction box. The inner component is combined with the aluminum frame by using a framing device, so that an alpha angle is concavely formed by the concave component along the short side direction, wherein the alpha angle is an included angle between the connecting line of the short side end point of the concave component and the connecting line of the short side middle point of the concave component, the alpha angle is 2-0.3 degrees, and the longitudinal direction of the component is kept straight. The invention provides a novelconcave component framing method, which uses a curved frame and utilizes the self-toughness of the component to make the component concave to form a concave surface, and the component is concavely formed with a curved reflecting surface, so that multiple reflections are formed on the surface of the component, thereby increasing the amount of incident of the secondary reflected light, and increasing the power generation output of the power station.

Description

Technical field [0001] The invention relates to a high-power component, in particular to a new type of concave component. Background technique [0002] The contradiction between energy supply and demand in my country is becoming increasingly fierce. The new energy industry represented by photovoltaic power generation will take on the important task of solving energy problems. How to increase power generation is a long-term problem that people have explored. It is known that the original dual-glass module structure is glass + packaging material + cell + packaging material + glass + aluminum frame. When installing this module, the surface of the module is always flat due to the aluminum frame support, but this does not improve light utilization. rate. If the aluminum frame is squeezed to form an arc, the components can directly form a concave surface after assembly, and the components form a concave surface, and the actual outdoor power generation will increase.
