Description

Technical Field

[0001] The utility model belongs to the technical field, and particularly relates to a highly reliable and long - life photovoltaic module. Background Art

[0002] Photovoltaic modules utilize the photovoltaic effect, that is, when light shines on a semiconductor material, it causes a potential difference inside the semiconductor, thereby generating an electric current, which is a physical phenomenon. Photovoltaic modules mainly consist of photovoltaic cells (i.e., solar cells), encapsulation materials, junction boxes, brackets, etc. Photovoltaic cells are the central part of photovoltaic modules and are usually made of semiconductor materials such as silicon and cadmium telluride. When sunlight shines on the photovoltaic cells, photons interact with electrons in the semiconductor material, causing the electrons to jump from the valence band to the conduction band, generating free electrons and free holes. The free electrons and free holes form an electric field inside the semiconductor, thereby generating an electric current. The encapsulation materials are used to protect the photovoltaic cells and prevent the influence of the external environment on the cell performance.

[0003] However, the structures of photovoltaic modules currently used in the market will face factors such as the aging of connection joints and support joints during long - term use. Under the influence of these factors, and affected by strong weather and climate, these photovoltaic modules will experience situations such as lodging and damage and cannot be used directly.

[0004] Therefore, the utility model provides a highly reliable and long - life photovoltaic module. The present application utilizes the extension of the structure on the back of the longitudinal frame to expand the structural strength of the photovoltaic module and improve the service life of the photovoltaic module. The present application uses the winding devices on the left and right sides of the inner wall of the longitudinal frame to cooperate with the cover cloth to complete the back shielding and dust prevention and preliminary wind resistance treatment processes. At the same time, the folding support structure can cooperate with the pull rope to perform flexible traction and tension support processes.
