Floating Solar Photovoltaic system
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.

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.

Uniqueness of the Solution
  • Floating Modules constructed from HDPE pipes with internal compartments, providing a robust platform for mounting solar panels, shades, or other equipment 
  • Modular Design allows easy deployment and scalability with quick-release connections (clamps/ropes) and optional boat lanes for maintenance 
  • 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 
  • Cost Reduction for FSPV structural systems ( from Rs. 15-20/Wp to Rs. 4-8/Wp) 
  • Eco-Friendly: Uses UV/corrosion-resistant HDPE, compliant with water standards 
  • Algal Bloom Mitigation: The system’s shading helps reduce algal blooms, and the potential integration of aerators can aid in lake rejuvenation
Current Status of Technology

A pilot project based on an earlier design is operational in Powai Lake. The updated design, incorporating HDPE floaters with internal compartments and floating sub-anchors, is ready for prototyping and further pilot demonstrations.
