The materials of floating solar systems mainly include high-density polyethylene (HDPE) and stainless steel. These materials have good corrosion resistance and weather resistance, and can meet the needs of long-term floating on the water surface.
High-density polyethylene (HDPE)
HDPE is a commonly used floating body material with the following characteristics:
Strong corrosion resistance : HDPE can resist the erosion of chemicals in the water and extend its service life.
Good weather resistance : HDPE material has good weather resistance and can work stably under various climatic conditions.
Environmentally friendly : HDPE is non-toxic and harmless to water bodies, ensuring safety of use .
Stainless steel
Stainless steel materials are also commonly used in floating solar systems, and their characteristics include:
High strength : Stainless steel has high strength and corrosion resistance, and can be used for a long time in harsh environments.
Strong durability : Stainless steel has a long service life and is suitable for use in marine environments .
Specific application examples and industry standards
In specific applications, the floating body of a floating solar system is usually made of HDPE material and made into a buoy through a blow molding process. These buoys are rigorously tested and quality-controlled to ensure they can meet their 25-year design lifespan. For example, some buoys are still in good condition after 20 years at sea, with only slight aging of the surface. In addition, the formulation of industry standards also provides guarantees for product quality and service life, such as the National Energy Administration's "NB_T 10187-2019 Technical Requirements and Test Methods for Floating Bodies for Floating Photovoltaic Systems".
