What Is The Core Demand of Floating PV Power Station?

What is the core demand of floating pv power station?

Five years ago, people still gave a smile that they did not trust floating pv or were worth looking forward to it. Five years later, with the floating power stations covering all continents except Antarctica, the status of floating power stations on water surface was no longer questioned inside and outside the industry, and it even was honored as "the future of photovoltaic industry" and "the third pole of photovoltaic industry". In the global scope, floating power station is no longer an optional option, but as an efficient form of photovoltaic application, it is widely used. The advantages of non occupation of land resources and high power generation have attracted much attention. However, under the background of affordable price and the special application environment of water surface, we can not help but ask: what is the core appeal of floating power station on the water surface ?

As an early enterprise engaged in the research and development of photovoltaic equipment and technology on the water surface, the solar power water surface photovoltaic (hereinafter referred to as "sunshine surface photovoltaic") has been in the forefront of industry exploration, providing the water surface photovoltaic equipment and system for coal mining subsidence areas in Anhui and Shandong, which are extremely cold regions in Northeast China and Japan, where is typhoon areas in East and South Asia. As for the core demands of floating power stations, sunshine water photovoltaic has conducted a long-term survey with global customers, and it was found that environmental protection, service life, safety and stability have always been common problems, which are also the core demands of the industry for floating power stations.

Do not forget the original intention, environmental protection should be put in the first place. Photovoltaic power generation is a green, pollution-free, sustainable and renewable way to obtain new energy. This is the starting point for people to vigorously develop the photovoltaic industry, which is also the original intention and original aspiration of the photovoltaic industry. Therefore, for the floating power station on the water, environmental protection is one of the priority issues.

According to the solar water photovoltaic system, the floating power station is generally composed of floating square array, anchoring system, inverter boosting floating ship, electrical system, etc. The anchoring system is composed of concrete and stainless steel. The inverter boosting floating ship provided by solar photovoltaic on the water surface adopts environmental protection paint. While, the floating square array is generally composed of floating bodies, floating pv brackets and connecting pieces, among which the floating body has large amount and long-term contact with water body, so the floating body material is the key. Food grade high density polyethylene (HDPE) is used as raw material for solar water photovoltaic. The material has good temperature adaptability, good chemical stability and high mechanical strength. It is non-toxic and tasteless. The product adopts hollow design scheme instead of foam filling material such as foam plastics, which has been basically eliminated at home and abroad. This scheme will draw further apart from the original intention of PV industry because of water pollution caused by the floating body's split.

Water sampling by testing agency
In addition to strict control of raw materials and the use of high-quality HDPE raw materials from regular manufacturers, the modification, upgrading and optimization of the materials were also carried out for the solar water photovoltaic, and the strict test was carried out on the finished spline. International authoritative testing institutions such as TüV Nande, Hong Kong Jialigo test center and other international authoritative testing institutions were entrusted to carry out a number of tests according to relevant Chinese national standards and British standards for drinking water contact materials. The test results show that the floating material is environmentally friendly and pollution-free. In addition, 36 tests including total phosphorus, nitrate and chemical oxygen demand were carried out on two large floating power stations on the water surface operated before and after 2016. The results showed that the water quality met the European surface water standards, the European Union drinking water quality directive and the WHO drinking water quality standards.

Security and stability can ensure long-term benefits.
The water surface environment is complex, especially in the waters with big wind and waves. There may be the changeable climate and high water level drop, which puts forward higher requirements for photovoltaic equipment and system on the water surface. The safety and stability of products and systems are another core demands of the water surface photovoltaic power station. Only safety and stability can ensure long-term benefits.

In terms of the product design, the solar water photovoltaic system carried out system analysis test for the key performance of the floating body, combined with external resources to develop new rapid detection instruments, and established an effective evaluation method, which solved the problem of evaluating the service life of the floating body in the photovoltaic industry and even the modified plastic industry. In addition to meeting the requirements of conventional strength, anti-corrosion and high weather resistance, the product design also carries out professional creep simulation according to the national standards and the industry requirements that the service life of photovoltaic power station is not less than 25 years, so as to ensure that the product design meets the requirements.

In the aspect of system design, under the premise of the established goal, the sunlight water surface photovoltaic system checks the wind load, snow load, anchorage reliability, square array stability and the stress strength of individual parts, so as to ensure the safety and stability of the products, and issue professional simulation reports to ensure that the design and verification process has rules to follow. According to the design content of multi round evaluation scheme of specific project, the paper demonstrates repeatedly from the aspects of operation and maintenance convenience, installation convenience, overall stability, component compatibility, etc. The overall scheme design of solar water photovoltaic can be flexibly adjusted by square array buoyancy to meet the requirements of different snow loads, ensuring the scientific and reasonable buoyancy and adapting to different environments.

The era of parity is coming. It is an irreversible trend to reduce cost and increase efficiency. Sunwater Photovoltaic said that while pursuing cost reduction, we can not ignore the core demands of the water surface photovoltaic, and even need to pay more attention to it because this is the foundation of healthy and sustainable development of the industry. Therefore, we firmly oppose "reducing costs" through cutting corners and opportunism and strive to reduce costs through technological innovation.
