Floating PV (FPV) systems, also known as floating solar farms, are an emerging technology that integrates photovoltaic panels on water surfaces such as reservoirs, lakes, and oceans. FPV research focuses on enhancing energy efficiency, optimizing system design, mitigating environmental impact, and improving durability in various aquatic environments.
1. Performance Optimization and Cooling Effects
- Research investigates temperature reduction effects due to water cooling, which enhances PV efficiency by 5–15%.
- Active cooling systems using water circulation and evaporative cooling are being tested to further increase power output.
- Bifacial PV modules are explored to capture reflected sunlight from water surfaces, improving energy yield.
2. Grid Integration and Hybrid Renewable Systems
- FPV-Hydropower Hybrid Systems: Research explores co-located FPV and hydroelectric plants to provide stable power generation by combining solar and hydro resources.
- Energy Storage Integration: Investigating battery storage and hydrogen production for better energy dispatchability.
3. Advanced Floater Materials & Structural Innovations
- Development of lightweight, high-strength floaters using HDPE (High-Density Polyethylene), fiber-reinforced composites, and corrosion-resistant aluminum alloys.
- Research on biodegradable and recyclable floating materials to reduce environmental impact.
- Modular and interlocking floater designs for scalable and flexible FPV installations.
4. Demonstration Projects
- Demonstration FPV 5kW plant and mobile FPV for agriculture irrigation at Puspiptek lake, Serpong;
- Feasibility studies of FPV power plant at Lake Towuti (South Sulawesi); Sigura-gura (North Sumatera), etc
