Technical Field

[0002] The ocean, which occupies 70% of the earth's surface, not only has rich resources such as aquatic products and oil, but also contains huge energy resources. Ocean energy mainly exists in the form of tides, waves, temperature differences, salinity gradients, ocean currents, etc. The utilization of ocean energy has great potential, and it is of great significance to increase the development and research of ocean energy.

[0003] Offshore photovoltaics is another important form of offshore energy utilization. Compared with land photovoltaics, offshore photovoltaics has natural environmental advantages. The water surface is open and there are no obstructions. The sunshine is long and fully utilized, which can significantly increase the power generation. The power generation of offshore photovoltaics is 5%-10% higher than that of land photovoltaics. It occupies less land and is easy to combine with other industries.

[0004] When photovoltaic panels are used in severe cold environments, their surface is prone to ice formation, which will greatly reduce the power generation of the entire system. Existing methods of breaking ice for offshore photovoltaic panels are mostly done manually. Workers take kayaks to break ice for photovoltaic panels along the way. The operation is dangerous and takes a lot of time. It can only remove ice from the photovoltaic panels. The residual ice water will still cause the photovoltaic panels to freeze again, which has no anti-icing effect. Workers are required to conduct regular inspections, which is labor-intensive and inefficient. Summary of the invention
