Floating Photovoltaic System Mount - TGW03 series

I. Convenient Construction Features

• • High Installation Efficiency: The guide rail and front/rear support structure design is relatively simple, the installation process is clear, and construction operations are convenient, which can shorten the on-site operation cycle to a certain extent.

• • Flexible Layout Adjustment: The spacing between photovoltaic modules can be adaptively adjusted according to the actual requirements of different latitudes and installation tilt angles, which is beneficial to improving the light-gathering efficiency of photovoltaic modules.

II. System Adaptability

• • Adjustable Installation Angle: The module installation tilt angle supports adjustment within the range of 0° to 15°, which is convenient for matching the irradiance conditions of different regions.

• • Flexible Wiring Methods: Cable channels can be flexibly laid in a north-south or east-west direction according to the site layout, which can adapt to the cable routing requirements of different sites.

• • Diverse Anchoring Methods: Supports multiple anchoring schemes such as onshore piling anchoring, underwater piling anchoring, and concrete block anchoring, which can adapt to different geological conditions at the bottom of different water bodies.

III. Safety Performance Advantages

• • Operation and Maintenance Safety Design: The width of the operation and maintenance passage is no less than 460mm, and the buoyancy per unit area of ​​the floating body is greater than 198kg/㎡. The overlapping design between operation and maintenance passages helps to stably transfer buoyancy, providing a certain degree of safety for operation and maintenance personnel.

• • Load Relief Design: The U-shaped steel connectors adopt a hinged structure, which can release a certain degree of force under environmental loads such as wind and waves, contributing positively to the overall stability of the system.

• • Wind Resistance: Tested by the third-party organization SGS, under specific test conditions, the system can withstand a wind speed of 50m/s. The overall strength of the floating body is good, and no damage or significant deformation was observed during the test.

• • Comprehensive Testing and Certification: The product has a complete floating body test report, covering multiple aspects such as buoyancy testing, floating body wind tunnel testing, surface concentrated load testing, environmental cracking resistance and density testing, and chemical corrosion resistance testing, providing a basis for product reliability.

• • Design Service Life: The system is designed for a 25-year service life and has the ability to operate stably for a long time under reasonable operation and maintenance conditions, meeting the needs of long-term projects such as hydro-solar hybrid systems.

IV. Applicable Water Bodies

• • It can be widely applied to various water surfaces such as lakes, reservoirs, rivers (slow-flowing sections), and mining subsidence areas. It has a certain adaptability to water quality conditions and water level changes, and is highly practical.

Applicable Scenarios

▪ Reservoirs and lakes: Water areas that are not navigable or designated as drinking water source protection zones, suitable for implementing fish-solar hybrid or pure photovoltaic power generation systems.

 

▪ Slow-flowing rivers and channels: River sections with low flow velocity and relatively stable water levels.

 

▪ Mining subsidence areas: Abandoned mine pits with accumulated water, where land resources that are difficult to reclaim can be effectively utilized.

 

▪ Wastewater treatment plants and aquaculture ponds: Where the function of the water body does not conflict with the overall purpose of the water body, allowing for multi-functional space utilization.

 

Important Notes:

▶ Preliminary Survey Requirements:

A detailed survey of the water depth, water level fluctuations, maximum wind speed, maximum wave height, ice load (if applicable), and water corrosivity is required. This data will serve as input for anchoring and floating body design.

 

▶ Anchoring Design Requires Special Assessment:

The anchoring method and mooring scheme should be designed by an experienced technical unit based on geological and hydrological conditions to avoid system drift or collision due to anchoring failure.

 

▶ Anti-Biofouling Measures:

Long-term operation in warm waters may face biofouling such as algae and shellfish. It is recommended to assess whether additional antifouling coatings or regular cleaning are necessary based on water quality conditions.

 

▶ Regular Inspection and Maintenance:

This includes checking the integrity of the floating body, the tightness of connectors, anchor cable wear, and electrical wiring insulation. A quarterly or annual maintenance plan is recommended.

 

▶ Extreme Weather Response:

In areas prone to extreme weather events such as typhoons, strong convection, and extreme cold/freezing, the system's safety under extreme loads should be assessed. Temporary reinforcement or component tilt adjustments may be necessary.

 

▶ Ecological and environmental impact:

Floating photovoltaic systems may affect underwater illumination and dissolved oxygen. It is recommended to conduct an ecological impact assessment in advance in environmentally sensitive waters and to set up light-transmitting areas or oxygenation equipment as required.

 

 

Summary

Floating photovoltaic (PV) systems offer a technological solution that combines photovoltaic power generation with aquatic space. Based on a modular floating structure, this product incorporates adjustable supports, hinged connectors, and various anchoring methods, with targeted designs for ease of installation, system adaptability, and structural safety. Third-party testing has verified its good wind resistance and long-term operational potential under typical operating conditions. It is suitable for various non-navigable waterways such as lakes, reservoirs, and coal mining subsidence areas. However, in practical engineering applications, customized design and regular maintenance based on specific hydrological, geological, and meteorological conditions are necessary to ensure the system's stability and safety throughout its entire lifecycle.
