Title: Analysis of solar system power required for 75 hp vessels With the popularization of environmental protection concepts and the development of renewable energy technology, solar energy systems have been widely used in many fields as a clean and sustainable energy solution. Especially in the field of water transportation, the application of solar energy systems has gradually become a trend. This article will focus on the core topic of "solar system power required for 75hp vessels", focusing on how to reasonably match the solar system power to meet the actual needs of ships. 1. Understand the relationship between solar energy system and marine power Solar energy systems provide power or auxiliary energy to ships by harvesting sunlight energy and converting it into electricity. Understanding the power conversion efficiency of the solar system and the horsepower requirements of the vessel is the key to choosing the right solar system. Second, the relationship between conversion horsepower and kilowatts Horsepower and kilowatts are both units of power, but in solar system applications, we use kilowatts more often. Usually, 1 horsepower is equal to about 0.735 kilowatts. Therefore, for a 75 horsepower boat, we need to convert it to the corresponding kilowatt to evaluate the required solar system power. 3. Determine the power required for the solar energy system When determining the power required for a solar system, factors such as the actual operating condition of the vessel, the intensity of solar radiation, and the hours of sunshine need to be considered. Generally speaking, the output power of a solar system needs to be able to cover the peak power demand of the vessel and have some energy storage capacity to cope with the lack of sunlight. For a 75-horsepower vessel, the required solar system power is typically between tens of kilowatts and hundreds of kilowatts. Fourth, the design and selection of solar energy system When designing a solar system, it is necessary to select the specific needs of the vessel and the horsepower analyzed above. The number, size, conversion efficiency of solar panels, and the capacity of energy storage devices such as batteries require careful planning and design. In addition, the integration and reliability of the system need to be considered to ensure that the system can operate stably under different environmental conditions. 5. Precautions for installation and maintenance The location and maintenance of a solar system is critical to the performance and longevity of the system. During the installation process, the structure and sunshine conditions of the vessel need to be fully considered to ensure that the solar panels can fully receive sunlight and convert energy efficiently. At the same time, regular maintenance and maintenance are also key links to ensure the normal operation of the system. 6. Analysis of economic benefits and environmental benefits The use of solar energy systems as a source of power not only reduces operating costs and emissions, but also contributes to the achievement of sustainable development goals. By comparing and analyzing the economic and environmental benefits of solar energy systems, we can better promote and apply the use of solar energy systems in the field of water transportation. Summary: This paper analyzes the relationship and influencing factors of the solar system power required by 75 horsepower vessels, and discusses how to reasonably select and configure solar energy systems to meet the actual needs of ships. At the same time, the importance of precautions in the design, installation, maintenance and other aspects of the solar energy system, as well as economic and environmental benefits, is emphasized. With the continuous progress of technology and the reduction of costs, the application prospect of solar energy system in the field of water transportation will be broader.
