Multipurpose Floating Structure: Solar Power and Shade
Abstract

This innovative structural system is designed for applications such as Floating Solar Power Plants (FSPV), floating shades, floating water treatment plants, and floating aerators. It utilizes cost-effective HDPE pipes and a modular design for easy deployment and maintenance. The system significantly reduces costs and enhances stability through the use of an underwater floating sub-anchor and maintenance boat lanes.

Problem Statement

Existing floating structures for solar power and similar applications are costly, complex, and often unstable under adverse weather conditions. Traditional designs necessitate expensive anchoring systems and overly robust floaters to ensure maintenance safety, leading to high costs and potential instability.

Uniqueness of the Solution
  • The floating modules constructed from HDPE pipes with internal compartments, provide a robust platform for mounting solar panels, shades, or other equipment. 
  • The system's modular design allows easy deployment and scalability with quick-release connections (clamps/ropes) and optional boat lanes for maintenance.
  • Its underwater floating sub-anchor, such as a steel truss supported by buoys, improves stability and reduces costs.
  • Boat lanes replace traditional walkways, enabling maintenance via boats, thus eliminating the need for high-cost floaters.
  • It allows for cost reduction for FSPV structural systems (from Rs. 15-20/Wp to Rs. 4-8/Wp).
  • It is eco-friendly, as it uses UV/corrosion-resistant HDPE, compliant with water standards. 
  • The system’s shading helps reduce algal blooms, and the potential integration of aerators can aid in lake rejuvenation.
