The Xisha Islands is one of the four major islands in the South China Sea, and it is an archipelago with a large land area in the South China Sea. Located in the central part of the tropics, the long sunshine time most of the year is very suitable for the construction of photovoltaic power plants. In order to meet the needs of electricity and water for production and living on the island, Sansha municipal government of Hainan province has started to build an independent photovoltaic smart microgrid project on the island since 2013. in order to improve and solve the problem of electricity and water for military and civilians on the island and improve the living conditions on the island, the construction scale will be expanded to 2MW in 2020.

The tropical monsoon climate of the Xisha Islands is one of the areas vulnerable to typhoons. There are 7 to 8 typhoons affecting the Xisha Islands every year. The air is full of water and salt, and the chloride ion in the salt has a particularly obvious erosion effect on the metal, so the island environment has a particularly high requirement for the corrosion resistance of the photovoltaic stent.

Xuke all-aluminum photovoltaic bracket with excellent material selection, beautiful and durable, wind and corrosion resistance and other characteristics from the market to join the construction of the project. In line with the craftsmanship spirit of keeping improving, Xuke team specially developed a new type of photovoltaic module installation guide rail for the 2MW photovoltaic project in Xisha Islands, and optimized four aspects on the basis of keeping the original system design of customers unchanged:

1. strong oxidation resistance, the overall support oxide film thickness of more than 20um

2. use 6005-T6 high-strength material, 1/3 higher hardness than traditional 6063 aluminum

3. superior structural performance, thickened T-nut anti-release design; Component guide rail double pressure block fastening design, quick and stable installation

4. 7-meter long-span aluminum load-bearing beam; The load-bearing beam has been changed from the original design steel to aluminum alloy, which greatly improves the convenience and corrosion resistance of structural installation.

Compared with the traditional steel bracket, the optimized and upgraded Xuke photovoltaic bracket has greatly improved the convenience and corrosion resistance of structural installation on the premise of meeting the wind resistance level, and can better adapt to the island environment and resist sea breeze and typhoon The impact of the photovoltaic power station ensures the service life of the photovoltaic power station to a greater extent. Due to the special geographical location of the Paracel Islands at the front line of the South China Sea border, the energy shortage problem of the Paracel Islands has always been an urgent problem to be solved. The use of 2MW photovoltaic power plants will definitely make a good supplement to local energy and help the development of local economy and industry.
