Floating Solar FPV in Water-Scarce Regions: Water-Energy Nexus and Sustainability


Water scarcity is a pressing global issue, and its intersection with renewable energy generation requires careful consideration. Floating solar photovoltaic (FPV) systems offer a sustainable solution by utilizing water bodies for clean energy production. This article explores the potential of floating solar FPV in water-scarce regions, focusing on the water-energy nexus and its implications for sustainability.

  1. The Water-Energy Nexus

    The water-energy nexus refers to the interdependence between water resources and energy production. Traditional energy generation methods often require significant water withdrawals for cooling and operational purposes, putting strain on already limited water supplies. Floating solar FPV presents a unique opportunity to mitigate this strain and promote sustainability.

    By deploying floating solar PV systems on water bodies, two key benefits emerge. First, the water surface reduces the ambient temperature of solar panels, enhancing their efficiency and power output. Second, the floating platforms help reduce evaporation, preserving water resources. This integration of renewable energy generation and water conservation offers a compelling solution for water-scarce regions.

  2. Sustainable Water Management

    Floating solar FPV systems can contribute to sustainable water management practices in water-scarce regions. By reducing evaporation, these installations help conserve precious water resources, particularly in regions facing drought conditions or struggling with water scarcity.

    Moreover, the shading effect of floating solar PV systems can minimize the growth of algae and reduce water contamination, thereby enhancing water quality. This co-benefit aligns with sustainable development goals, as it improves the availability of clean water for local communities and ecosystems.

  3. Synergies with Water Infrastructure

    Water-scarce regions often rely on reservoirs and other water bodies for both water supply and electricity generation. Floating solar FPV systems can be integrated with existing water infrastructure, providing dual benefits of renewable energy generation and optimized water management.

    For instance, floating solar panels installed on reservoirs can reduce evaporation, allowing more water to be available for municipal, agricultural, and industrial use. Additionally, the electricity generated by floating solar FPV systems can be utilized for on-site water treatment processes, enhancing water supply reliability and reducing reliance on grid electricity.

  4. Economic and Environmental Considerations

    Floating solar FPV in water-scarce regions brings economic and environmental advantages. In terms of economics, these installations offer an opportunity for renewable energy diversification and reduced reliance on fossil fuel-based power generation. The scalability and modularity of floating solar FPV systems make them suitable for various water bodies, including reservoirs, lakes, and wastewater treatment ponds.

    From an environmental perspective, floating solar FPV contributes to greenhouse gas emissions reduction and the mitigation of climate change. By displacing conventional fossil fuel-based energy sources, these systems help to reduce carbon emissions, air pollution, and the ecological impact of water-intensive energy generation.


Floating solar FPV systems in water-scarce regions offer a sustainable and innovative approach to the water-energy nexus. By integrating renewable energy generation and water conservation, these installations contribute to sustainable water management, improve water quality, and promote environmental stewardship.

The benefits of floating solar FPV extend beyond water conservation and include economic advantages, such as renewable energy diversification and reduced greenhouse gas emissions. To maximize the potential of floating solar FPV in water-scarce regions, policymakers, energy planners, and water resource managers must collaborate to develop supportive frameworks and regulations.

As water scarcity continues to be a global challenge, embracing floating solar FPV as a viable solution can drive the transition towards a sustainable and resilient future. By harnessing the power of the sun and conserving water resources, floating solar FPV demonstrates its potential as a key player in achieving a more sustainable water-energy nexus.
