Description

Technical Field

[0002] With the increasing global demand for renewable energy, solar photovoltaic (PV) power generation systems are gradually becoming mainstream as a clean and renewable energy solution. The efficient conversion of solar PV power generation systems relies heavily on connectors, a key component that not only ensures stable and reliable electrical connections between PV modules but also helps them adapt to complex outdoor environments.

[0003] With the full development of terrestrial new energy resources, people are in urgent need of finding the next resource territory. The abundant wind and solar energy resources of the ocean and lakes provide more room for development, especially for coastal countries with high population density and scarce land resources.

[0004] Offshore photovoltaic systems are unobstructed by water, which lowers the operating temperature of the modules and thus increases power generation. However, offshore photovoltaic systems also face adverse factors such as strong winds, waves, and strong corrosion. Therefore, offshore photovoltaic modules require more stable and corrosion-resistant materials and structures.

[0005] As junction boxes responsible for transmission and connection between photovoltaic modules, connectors also need better corrosion resistance and connection stability. Utility Model Content
