Take you to know the water surface floating photovoltaic power station


In recent years, with a large increase in the number of photovoltaic power plants on the road, there is a serious shortage of land resources available for installation and construction, which restricts the further development of this type of power plant. At the same time, another branch of photovoltaic technology - floating power station into the people's view.

Compared with traditional photovoltaic power plants, floating photovoltaic is installed on the water surface floating body, in addition to not occupy land resources, conducive to people's production and life, the body of water on the photovoltaic modules and cable cooling can also effectively improve the efficiency of power generation. Floating photovoltaic power plants can also reduce the evaporation of water, inhibit the growth of algae, which is beneficial to aquaculture and daily fishing catch.

Floating photovoltaic power plants

In 2017, the world's first floating PV power plant 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 one "moving" and one "wet".

The "motion" refers to the wind and wave flow simulation calculation. Since the floating PV modules are above the water surface, unlike the constant static state of conventional PV, 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 floating body structure to ensure the safety of the floating arrays; among them, the adaptive water level anchoring system of the floating arrays uses ground anchor piles with sheathed steel ropes to connect with the edge reinforcement of the attached arrays, and each arrays Anchoring point is set every 6 meters, and the cable is left with a margin to ensure uniform force, safety and reliability, and to achieve the best coupling of "dynamic" and "static".

The "wet" refers to the comparison of the reliability of double-glass modules, N-type modules and PID-resistant conventional non-glass back panel modules in wet environment for a long time, and the verification of the impact on power generation, and the verification of the durability of floating body materials, etc., in order to ensure the safety of the floating power plant design life of 25 years, and to provide reliable data support for subsequent projects. Data support.

Floating power station can be built on a variety of water bodies, whether it is a natural lake, artificial reservoir or coal mining subsidence area, sewage treatment plant, as long as there is a certain amount of water for equipment installation. When floating power plants meet the latter, not only can "waste water" be regenerated into a new power plant carrier, but also can maximize the self-cleaning ability of floating photovoltaic, by covering the water surface to reduce evaporation, inhibit the growth of microorganisms in the water and thus achieve the purification of water quality. Floating photovoltaic power plant can make full use of water cooling effect to solve the cooling problem encountered by road photovoltaic power plant, and at the same time, because there is no shade over the water, fully exposed to light, floating power plant is expected to improve the power generation efficiency by about 5%.

After years of construction and development, the tight land resources and the impact of the surrounding environment make the road photovoltaic layout is greatly restricted, even if it can be expanded to a certain extent by developing desert and mountainous areas, but still belongs to the treatment of symptoms but not the root cause. With the development of floating photovoltaic technology, this new type of power plant does not need to grab precious land with residents, but turn to a broader water space, and road surface to form a complementary advantage, to achieve a multi-win situation.
