Floating Photovoltaic Solutions: Innovative Technology and Global Application Analysis
After understanding traditional photovoltaic solutions such as centralized, distributed, rooftop, and agricultural greenhouse. In recent years, the new form of water-based photovoltaic solutions has gradually attracted people's attention. With the continuous tightening of land policies for photovoltaic power stations, the development space in this field is gradually emerging, and floating photovoltaic solutions have become a new investment hotspot as a result.
1. Overview of floating photovoltaic solutions
1.1 Concept of floating photovoltaic solutions
Floating PV solutions are one emerging form of energy that generates electricity by placing photovoltaic modules on water bodies. This form of power station utilizes the vast space of water bodies and provides an innovative solution for photovoltaic power generation. With the increasing scarcity of land resources, it has gradually become a highly concerned investment hotspot.
1.2 Technical composition and advantages
The core components of a floating photovoltaic solutions on water include photovoltaic panels, combiner boxes, inverter equipment, transformers, collection lines, and polyethylene floating platforms. Among them, the floating platform is one of the key parts of the power station, which plays an important role in stabilizing and supporting photovoltaic modules in water. By placing photovoltaic panels on a floating platform, the power station can effectively generate electricity on the water surface. This design not only simplifies the construction process, but also significantly improves the efficiency of photovoltaic power generation.
2. Examples and technical details
2.1 Utilization of coal mining subsidence areas
During the coal mining process, surface subsidence often occurs due to the extraction of underground coal seams. This kind of subsidence not only affects the use of land, but may also cause damage to the surrounding ecological environment. However, this so-called 'subsidence area' can be effectively utilized through the development of photovoltaic projects. By constructing photovoltaic power stations on water bodies in subsidence areas, not only has the economic value of the region been increased, but the power generation efficiency can also be significantly improved. Due to the natural cooling effect of water, the temperature of the solar panel decreases, thereby increasing the power generation capacity of the photovoltaic module.
2.2 Achievements and challenges of subsidence area renovation
The transformation of subsidence areas has brought many advantages, such as significantly improving the economic value of water bodies, promoting economic growth through comprehensive utilization of water bodies, and significantly increasing the power generation of photovoltaic power plants. However, this transformation also faces some challenges, such as the need for floating devices to have excellent corrosion resistance and low density characteristics to ensure long-term reliable operation in humid environments.
2.3 Construction and Global Applications
The construction complexity of floating photovoltaic power plants on water mainly stems from the special nature of the water environment, which makes it difficult to use heavy machinery for efficient construction. Therefore, the project requires innovative design schemes and refined management measures. However, its innovative design and efficient returns have been validated in multiple countries. At present, floating photovoltaic technology on water has been widely applied and practiced in Japan, India, South Korea, Singapore, the United Kingdom and other places, achieving significant success. Especially in Japan, due to its relatively limited land resources, they actively develop water resources and continuously optimize photovoltaic technology through long-term practice.
