What Are the Main Applications of Floating Solar Solutions?
Floating solar solutions are gradually becoming an important force in the global energy transition. Its biggest advantage is that it does not occupy valuable land resources, and thanks to the cooling effect of water bodies, its power generation efficiency is usually 5% to 8% higher than traditional ground power stations. At present, the applications of floating solar solutions have expanded from simple inland waters to complex marine and extreme environments, which can be mainly classified into the following categories.
1. Inland Waters and Ecological Restoration
This is currently a widely used field for floating solar solutions, achieving a harmonious coexistence of "water power generation and underwater ecology". Installing floating solar solutions in drinking water reservoirs not only generates electricity, but also effectively blocks sunlight and reduces water evaporation. In addition, abandoned water bodies in coal mining subsidence areas can be turned into treasures, or a "fishery photovoltaic complementary" model can be implemented in agricultural irrigation reservoirs and aquaculture ponds. By controlling the contact coverage between floating bodies and water surfaces, the dual benefits of fishery and photovoltaic power generation can be achieved while ensuring the dissolved oxygen content of the water.
2. Ocean and Deep Sea Development
With the advancement of technology, floating solar solutions are stepping towards the ocean, exploring the comprehensive utilization of "energy islands". In response to challenges such as seawater corrosion, biological attachment, and tidal fluctuations, the new floating PV system adopts specially designed floating bodies and supports that are resistant to salt spray corrosion and barnacle attachment, as well as an underwater anchoring system that can adapt to large tidal drops. In deep-sea areas, semi-submersible, bamboo based composite materials, or carbon fiber cable net structure floating solutions are exploring new models for the comprehensive utilization of marine new energy, including "fish farming in water, surface power generation, hydrogen production at sea, and green alcohol supply to ships".
3. Extreme Environments and Special Working Conditions
The floating photovoltaic system, with its highly customized anchoring and structural design, can adapt to various extremely harsh natural environments. In areas with frequent typhoons such as the Philippines, floating solutions can withstand the invasion of strong typhoons through scientific wind load calculations. In places such as the Jirata Reservoir in Indonesia, floating power stations have successfully overcome the huge challenges of water depths of up to 100 meters and water level fluctuations of up to 18 meters. In addition, in the face of special water quality such as strong acidity, specially designed floating materials can also ensure the long-term stable operation of the power station.
4. Industrial Integration and Emergency Support
In addition to large power stations, photovoltaic floating solutions also demonstrate unique flexibility in industrial transformation and emergency support. Constructing floating power stations on industrial water pools of high energy enterprises such as steel and chemical plants can absorb green electricity on site, providing a demonstration for the green transformation of enterprises. At the same time, at the construction site of water conservancy projects, small floating photovoltaic solutions or vehicle mounted emergency power stations can quickly provide energy for monitoring equipment, drainage pumps, etc., without the need to set up cumbersome temporary lines, becoming a new tool for water conservancy emergency support.
At present, the application of floating solar solutions is constantly expanding, from inland lakes and reservoirs to vast and far-reaching seas, from ecological restoration to industrial integration. With extremely high environmental adaptability and diverse "photovoltaic+" modes, it provides a highly potential solution for the development of global clean energy.
