Floating Solar PV

Solar Power That Floats – An Introduction to Floating PV

Floating solar PV systems use modular solar panels mounted on buoyant platforms that rest on the surface of water bodies—such as reservoirs, lakes, canals, and industrial ponds. These platforms are engineered to stay afloat while securely supporting photovoltaic modules, inverters, and necessary wiring.

Unlike traditional land-based setups, floating solar panels come with anchoring and mooring systems that prevent drifting and withstand wind, waves, and water level variations. The inverters and transformers are typically mounted either on the platform or nearby onshore structures, depending on the scale of the installation.

What makes floating solar technology stand out is its dual advantage: it generates clean energy while reducing water evaporation. Plus, the natural cooling effect of water improves panel efficiency, often outperforming land-mounted solar plants in terms of energy output per panel.

Proven Engineering & Deployment for Floating Solar Farms

WattNexx brings deep technical expertise in executing floating solar PV systems—from design to grid connection. Our turnkey EPC model ensures every stage is covered: hydrological analysis, system design, float selection, procurement, and final installation.

We use high-durability floats and anti-corrosive mounting structures engineered to withstand long-term exposure to water, wind, and heat. All components are selected for rugged performance and compliance with global standards.

Every project is tailored. We adapt the anchoring and mooring design to local wind speeds, water depths, and site-specific constraints, ensuring long-lasting stability and efficiency.

With experience across floating solar farms and floating solar plants, WattNexx delivers reliable, high-yield solar infrastructure on water.

Why Floating Solar Power is the Future of Clean Energy

• Improved solar efficiency – Water's natural cooling effect boosts the performance of floating solar panels compared to land-based setups.
• Optimized land use – Perfect for land-scarce regions, floating solar power converts idle water bodies into energy assets without affecting agriculture or urban development.
• Water conservation – Solar coverage reduces evaporation from reservoirs, helping manage water levels in hot, dry regions.
• Better water quality – Shading from floating solar technology curbs algae growth and keeps water cooler.
• Reduced dust accumulation – Fewer airborne particles mean lower cleaning needs and consistent output.
• Lower installation temperatures – Cooler surroundings extend equipment life and reduce system stress.

Where Floating Solar Works Best

As land becomes increasingly scarce and energy demands rise, floating solar PV systems offer a smart alternative for large-scale solar deployment. These systems utilize underused water surfaces to generate clean energy, without disrupting land use or operations.

Ideal applications include:

• Water reservoirs at thermal power plants
  Offset fossil fuel use by installing floating solar PV systems on cooling ponds and auxiliary reservoirs.
• Dams, canals, and irrigation tanks
  Turn long stretches of water infrastructure into active power-generating assets using marine solar power systems.
• Drinking water treatment facilities
  Lower operational energy costs by placing floating solar panels on water treatment tanks and holding areas.
• Industrial campuses with captive water bodies
  Use onsite ponds or wastewater tanks to host floating solar farms, powering facilities without additional land acquisition.
• CSR and government-led sustainability projects
  An ideal choice for corporates and municipalities aiming to combine clean energy adoption with water conservation.

Whether for private industry or public utilities, floating solar technology can turn idle water surfaces into high-efficiency energy hubs, sustainably and economically.
