Floating solar is making waves—literally—in the renewable energy space. By harnessing idle water surfaces like reservoirs, lakes, and dams, this technology tackles land constraints while unlocking new power potential. India is leading the charge with large-scale floating solar farms that deliver clean energy, conserve water, and use existing infrastructure more efficiently.
A Growing Global Trend
Floating solar, also known as floatovoltaics, has gained momentum worldwide. Countries like China, Japan, South Korea, and the Netherlands have been quick to deploy floating solar farms on lakes, flooded mines, and even offshore waters. China leads with several gigawatts of installed capacity, while Japan was among the earliest adopters, launching large-scale projects as early as 2007. Globally, floating solar capacity surpassed 5 GW by 2023, with massive potential still untapped.
In India, where land is at a premium and energy demand is surging, floating solar presents an ideal solution. Several states have announced ambitious plans, with projects being implemented on reservoirs and dam backwaters in Kerala, Maharashtra, Madhya Pradesh, and Gujarat.
Technological Advancements Powering the Shift
Recent innovations are making floating solar more efficient, durable, and viable at scale:
Bifacial Solar Modules: Absorb sunlight from both sides, boosting output by up to 20%.
Custom Anchoring Systems: Stabilize panels despite floods or water level changes.
Leak-Proof Floating Platforms: HDPE floats offer UV resistance and thermal stability.
Floating Inverter Barges: Reduce land use and improve transmission efficiency.
Environmental and Economic Benefits
Floating solar offers multiple advantages beyond clean electricity:
Water Conservation: By covering water surfaces, floating panels reduce evaporation, helping conserve millions of cubic meters annually.
Land Savings: They eliminate the need for expensive or fertile land, freeing up space for agriculture or development.
Algae Control: Shading from solar panels can inhibit algae growth in water bodies, improving water quality.
Emission Reductions: Projects can avoid over 100,000 tons of CO₂ emissions per year, contributing to climate goals.
India’s Floating Solar Journey: The Omkareshwar Case Study
One standout example is the Omkareshwar floating solar park, implemented on the backwaters of a major dam in Madhya Pradesh, central India.
The project, led by top renewable energy firms, incorporates many industry firsts:
•Over 240 MW of floating solar capacity has been developed in the initial phase.
•Use of bifacial glass-to-glass modules and FRP inverter barges sets new benchmarks for efficiency.
•Rock bolt anchoring and leak-proof floats ensure stability amid fluctuating water levels.
•Supports local employment and energy access, while also conserving water and reducing emissions.
This initiative underscores India’s ability to scale innovative green technologies and adapt them to diverse geographical challenges.
Future Potential and Global Outlook
With a planned expansion to 600 MW, this Indian case study reflects the potential for floating solar to grow across the world. As countries seek to balance development with environmental stewardship, floating solar offers a unique opportunity to:
•Repurpose existing water infrastructure (dams, canals, and reservoirs).
•Boost grid resilience in remote or land-constrained areas.
•Drive investments in renewable energy without competing for land.
According to industry estimates, India alone could install 15–18 GW of floating solar capacity by 2030, if supported by conducive policies, financing, and infrastructure.
