The urgent need to transition to renewable energy is driven by the limitations and environmental impact of fossil fuels. Solar energy, especially in coastal areas with abundant sunlight, presents significant potential. However, coastal environments pose challenges such as seawater corrosion, high humidity, strong winds, and complex geology, requiring innovative design solutions for solar power equipment. This study designs and implements a photovoltaic (PV) booster station on a high pile platform in a seawater environment. It includes detailed planning of platform structure, anti-corrosion measures, pile foundation selection, and seismic design. By optimizing the platform layout and selecting appropriate materials, the study aims to enhance solar energy efficiency and ensure system stability and durability. Geological surveys and suitable pile types ensure the station’s stability. Anti-corrosion strategies, using resistant materials and multi-layer coatings, extend equipment lifespan. Seismic design addresses coastal seismic activity. The project effectively tackles marine environmental challenges, improving solar energy use in coastal areas. The methods and findings offer valuable insights for similar renewable energy projects. The study recommends further research to optimize PV system design, develop advanced anti-corrosion technologies, and integrate multi-energy systems, promoting renewable energy application and supporting global energy transition.
