I  Project Overview

1. Project Introduction:Zhejiang Longshan 400MW Water Surface Pile Photovoltaic Power Station Project(圖1)

The project fully relies on the large-scale idle shallow tidal flats area of Longshan and relatively sufficient light conditions, and uses "photovoltaics +" as the development model to build a large-scale centralized fishing and light complementary photovoltaic power station with "upper power generation and lower fish farming". This new power generation model of "single land, dual use" not only greatly improves output efficiency, but also effectively promotes the transformation of the local energy structure and accelerates the development of energy construction in a green and healthy direction.

2. Construction Geological Conditions:

The construction site of the project is located in a shallow sea flat area, with flat terrain and superior development and utilization conditions. It is located on the southern edge of the northern subtropical zone and has a monsoon climate. The annual average temperature is 16.0℃, the northwest wind prevails in winter, and the southeast wind prevails in summer.

I  Project Features:

Water surface photovoltaic construction is different from ordinary photovoltaic projects. High humidity in the construction environment will cause serious PID effects and reduce power generation. Therefore, during the design and construction process:

1. The bottom of the pile shall enter the water bottom not less than 3m, and the pile end shall be higher than the water surface, and the reserved flood water level shall not be less than 0.4m.

2. Photovoltaic modules are laid on the water surface. As the water level changes, the boating cannot successfully complete the daily inspection. The cable tray is widened so that the cable routing and maintenance personnel can walk on it. At the same time, it can prevent the vigorous growth of vegetation such as aquatic plants and obstructing vessel maintenance.

3. A humid environment will also accelerate the corrosion of the metal parts of electrical equipment. The photovoltaic support and components are all galvanized materials to prevent the components from rusting and rotting when the environment is humid.
