AI Technical Summary

Technical Problem

In existing photovoltaic panels, the connecting layer cannot be connected stably with the metal backplane or photovoltaic module for a long time, resulting in the photovoltaic panels being unable to generate power or be damaged.

Method used

A connection structure is provided between the photovoltaic module and the connecting layer or between the metal backplane and the connecting layer to increase the contact area with the connecting layer. The connecting structure may include bumps, grooves, spikes, and columns, etc. to enhance the connection strength.

Benefits of technology

By increasing the contact area, the connection strength between the photovoltaic module or metal backplane and the connecting layer is increased, the probability of phase separation of the photovoltaic panels during long-term use is reduced, and the stable connection and normal power generation of the photovoltaic panels are ensured.

Abstract

The utility model discloses a photovoltaic panel, and relates to the technical field of photovoltaic panels. The photovoltaic panel comprises a photovoltaic assembly, a connecting layer and a metal backboard which are connected in sequence. A connecting structure is arranged between the photovoltaic module and the connecting layer, and / or a connecting structure is arranged between the metal back plate and the connecting layer; the connecting structure is at least used for increasing the contact area between the photovoltaic module or the metal backboard and the connecting layer. The connection structure capable of increasing the contact area with the connection layer is arranged between the photovoltaic module and the connection layer or between the metal back plate and the connection layer, so that the connection strength between the photovoltaic module or the metal back plate and the connection layer is improved, and the probability of separation of the photovoltaic module and the metal back plate in the long-term use process is reduced. Even if the photovoltaic module and the metal back plate can be stably connected for a long time, the probability that the photovoltaic panel cannot generate power or is damaged due to the separation of the photovoltaic module and the metal back plate is reduced.
