Additional Considerations for the General Layout of Floating Solar Power Plants

Introduction

Beyond the core elements discussed so far, several other factors must be considered when designing the general layout of floating solar power plants. These factors encompass the influence of surrounding structures, ensuring safe access and navigation, and designing appropriate protective measures for the power plant.

Impact of Surrounding Structures Floating Solar Power Plants

Line Tower Shadowing

It’s crucial to consider the potential impact of nearby line towers on the photovoltaic modules due to shadowing. Ideally, power lines should not traverse the photovoltaic area. If unavoidable, sufficient width should be reserved on both sides of the line to prevent shadowing and ensure maintenance access to the towers.

Dam and Embankment Considerations

If the site contains or is adjacent to dams, embankments, or similar structures, it’s essential to avoid placing photovoltaic modules too close to these structures. Maintain a safe distance between the modules and the dam top and base, and factor in any potential shadowing effects.

Anchoring for Floating Installations

 For floating solar power plants using shore-based anchoring, the safe distance between the modules and the dam should be calculated based on the anchoring length.

Fence Design of Floating Solar Power Plants

Fences for Land-Based Areas

If the photovoltaic area’s land acquisition falls outside the water level line (the area covered by the average annual water level), a standard fence similar to ground-mounted solar power plants can be used. Install an iron wire mesh fence with a minimum height of 1.8 m around the perimeter of the photovoltaic area.

Floating Barriers for Water-Based Areas

When the photovoltaic area falls within the water level line or experiences significant water level fluctuations, different approaches are needed:

Floating Platforms

For installations where the photovoltaic modules are far from the shore, a standard fence may not be necessary.

Floating Buoys and Markers

If the modules are closer to the shore or populated areas (e.g., villages), consider using floating buoys, warning signs, and water nets for perimeter protection.

Fences for Fixed Floating Solar Plants

 For fixed floating solar power plants, a fence design using support pipe piles with an iron wire mesh can be used. Ensure the fence height exceeds the difference between the highest and lowest water levels.

Waterway Access

To maintain safe vessel navigation, removable simple floats should be used to create temporary enclosures at the entrances and exits of waterways.

Conclusion

Beyond the core layout elements, ensuring safe access, minimizing potential impacts from surrounding structures, and implementing suitable protective measures are crucial for the successful operation of floating solar power plants. By carefully considering these factors, developers can optimize the safety, efficiency, and environmental impact of their floating solar installations.
