Description

Technical Field

[0001] This invention relates to the field of marine technology, and in particular to a foldable solar panel system for ocean-going vessels. Background Technology

[0002] As the International Maritime Organization (IMO) continues to raise its requirements for the Energy Efficiency Design Index (EEDI) of ships, ocean-going vessels operating globally are facing increasingly stringent energy conservation and emission reduction requirements. Solar energy, as a green and renewable energy source, can effectively promote carbon emission reduction in ocean-going fleets.

[0003] The application of solar energy in the marine sector has proven to have significant economic and environmental value. The advantages of marine solar panels include reduced carbon emissions, fuel cost savings, and significantly reduced noise levels. Solar panels can be categorized into rigid and flexible types based on panel type. Rigid solar panels are the most common, made by encapsulating crystalline silicon within a glass panel. During installation, the panel cannot deform and requires a suitable bracket to adjust parameters such as installation height and angle. Flexible solar panels, on the other hand, use resin-encapsulated amorphous silicon as the main photoelectric element, laid flat on a flexible substrate. During installation, the panel is allowed to deform moderately to conform to the desired surface, offering greater flexibility in installation.

[0004] However, due to factors such as raw material costs and manufacturing processes, flexible solar panels are more expensive and have a slightly lower energy conversion efficiency than rigid solar panels, limiting their current application. Projects involving the installation of solar panels on ships also primarily use rigid panels.

[0005] Currently, solar panels are mostly used on small ships, and less so on large ocean-going vessels. This is because ocean-going vessels have high energy consumption and require a large area for solar panels. Conventional ocean-going merchant ships cannot reserve enough space to install solar panels in order to ensure that normal operations are not affected. Only a few ship types with a large area of ​​unused deck have the conditions to install solar panels.

[0006] There are already successful cases of installing solar panels on ocean-going vessels. For example, the "COSCO Shengshi," a 5,000-vehicle roll-on / roll-off (Ro-Ro) ship under COSCO Shipping Specialized Carriers, has become the world's largest ocean-going vessel using on-grid and off-grid photovoltaic technology after undergoing a solar photovoltaic system retrofit project. The success of the "COSCO Shengshi's" photovoltaic system retrofit project is largely due to the characteristics of its Ro-Ro ship type. Its top deck is flat, open, and has ample area, requiring only fixed brackets to meet the needs of solar panel installation.

[0007] However, for most ocean-going vessels, in order to save onboard space and avoid interfering with normal operations, a solar panel system that is easy to deploy and retract must be used, while also taking economic considerations into account.

[0008] Currently, solar panel systems used on ocean-going vessels are all fixed structures, which occupy a lot of space and can easily interfere with normal operations on board. Therefore, only a few ship types are capable of installing solar panels. Summary of the Invention
