Floating photovoltaic
In recent years, with the large increase in pavement photovoltaic power plants, there has been a serious shortage of land resources that can be used for installation and construction, which has restricted the further development of such power plants. At the same time, another branch of photovoltaic technology, the floating power station, has entered people's field of vision.
Compared with traditional photovoltaic power plants, floating photovoltaics install photovoltaic power generation components on surface floating bodies. In addition to not occupying land resources and facilitating people's production and life, water body cooling of photovoltaic modules and cables can also effectively improve power generation efficiency. . Floating photovoltaic power plants can also reduce water evaporation and inhibit algae growth, which is beneficial to aquaculture and daily catch.
In 2017, the world's first floating photovoltaic power station with a total area of ​​1,393 mu was built in Liulong Community, Tianji Township, Panji District, Huainan City, Anhui Province. As the world's first floating photovoltaic, the biggest technical challenge is “moving†and “wetâ€.
“Moving†refers to the simulation calculation of wind and wave currents. Since the floating photovoltaic power generation component is above the water surface, unlike the constant static state of conventional photovoltaics, detailed wind and wave flow simulation calculations must be performed for each standard power generation unit to provide a basis for the design of the anchoring system and the floating body structure to ensure the floating side. The safety of the array; among them, the floating square array adaptive water level anchoring system uses the ground anchor pile and the sheathed steel rope to connect with the edge reinforcement of the attached square array, and each square array is provided with anchor points every 6 meters or so, and the cable stays. The remaining amount is used to ensure uniform force, safety and reliability, and achieve the best coupling of “moving†and “quietâ€.
“Wet†refers to the long-term reliability comparison between the double-glass components of the water project, the N-type battery components and the anti-PID conventional non-glass backboard components in the humid environment, and the impact on the power generation, and the durability of the floating material. Verification, etc., to ensure the safety of the floating power plant design for 25 years, and provide reliable data support for subsequent projects.
Floating power stations can be built on a variety of water bodies, whether natural lakes, artificial reservoirs or coal mining subsidence areas, sewage treatment plants, as long as there is a certain amount of water can be installed equipment. When the floating power station encounters the latter, it can not only regenerate the "waste water" into a new power station carrier, but also maximize the self-cleaning ability of floating photovoltaics, reduce the evaporation amount by covering the water surface, and inhibit the growth of microorganisms in the water. Achieve the purification of water quality. The floating photovoltaic power station can make full use of the water cooling effect to solve the cooling problem encountered by the pavement photovoltaic power station. At the same time, because the water area is unobstructed and the light is sufficient, the floating power station is expected to increase the power generation efficiency by about 5%.
After years of construction and development, the impact of the tense land resources and the surrounding environment has greatly limited the layout of the road PV. Even if it can be developed to a certain extent through the development of deserts and mountains, it still belongs to the palliative. With the development of floating photovoltaic technology, this new type of power station does not need to rob the valuable land with the residents, but instead turns to a broader water space, complementing the road surface to achieve a multi-win.
