To address this challenge, the emergence of floating solar panels, also known as floating photovoltaics or “floatovoltaics,” presents a promising solution. By deploying solar panels on bodies of water like non-recreational lakes or reservoirs, floating solar systems offer a range of benefits that go beyond space efficiency..
What are Floating Solar Panels?
Floating solar panels are photovoltaic systems that float on water bodies, leveraging large bodies of water for solar energy generation. They are typically installed on lakes, reservoirs, or industrial ponds, utilizing polyethylene floats to keep the panels above water and angled towards the sun.
Tethers secure the panels in place, preventing drift and ensuring optimal sun exposure. This innovative approach to solar deployment has gained traction globally, with floating solar systems accounting for a growing percentage of solar installations worldwide.
Why are Floating Solar Panels Used?
Optimal Space Utilization: Floating solar panels maximize space utilization by tapping into bodies of water that are not used for recreational activities. This approach enables the effective use of otherwise unused expanses, optimizing land use efficiency.
Environmental Preservation: Unlike ground-mounted solar farms that may require land clearing, floating solar panels have minimal impact on terrestrial ecosystems. They can coexist with existing land uses and conservation efforts, preserving natural habitats and biodiversity.
Enhanced Performance: Water-cooled solar panels exhibit improved efficiency compared to their land-based counterparts, benefiting from natural cooling effects. This boost in efficiency translates to higher energy production and better return on investment (ROI).
Benefits of Floating Solar Panels
Reduced Water Evaporation: Floating solar panels reduce water evaporation from lakes and reservoirs by blocking direct sunlight. Studies suggest that covering 30% of global reservoirs with floating solar could save enough water to serve millions of people annually.
Algae Prevention: The shading effect of floating solar panels inhibits algae growth, improving water quality and ecosystem health. This benefit extends to enhanced safety for aquatic life and reduced risks of harmful algal blooms.
Carbon Emission Reduction: Floating solar systems complement existing hydroelectric dams, offsetting their carbon footprint and enhancing renewable energy generation. They contribute to cleaner energy production and environmental sustainability.
Tourism and Aesthetics: Some floating solar installations, like the one in Ubon Ratchathani, Thailand, double as tourist attractions. The integration of solar panels with recreational areas underscores their visual appeal and eco-tourism potential.
Challenges of Floating Solar Panels
Despite their numerous benefits, deploying floating solar panels presents unique challenges:
Harsh Environmental Conditions: Water-based installations face challenges such as high wind speeds, water erosion, and potential contaminants. Robust materials and design considerations are necessary to withstand these elements.
Wildlife Impacts: Careful site selection is essential to minimize impacts on aquatic life. Tethers and installation activities can pose risks to wildlife, necessitating strict adherence to environmental regulations and monitoring protocols.
Complex Installation Process: Floating solar systems require meticulous planning and installation due to the complexity of mooring and anchoring systems. Electrical safety measures are critical when working in water environments.
