Floating Solar Photovoltaic (FPV) Systems — Solar on Water. Power Without Land.
Ellence Energy LLP is at the forefront of designing and installing floating solar PV systems on reservoirs, lakes, ponds, and water bodies — generating clean energy without occupying a single square metre of land.
What Is Floating Solar (FPV)?
Floating photovoltaic (FPV) systems mount solar panels on buoyant structures placed on the surface of water bodies — reservoirs, lakes, ponds, canals, and irrigation tanks — generating clean energy without using land.
Ellence Energy LLP is at the forefront of designing and installing floating solar photovoltaic (FPV) systems across India. As land becomes increasingly scarce and expensive for solar development, floating solar offers a powerful alternative — generating renewable energy from the surface of water bodies that would otherwise remain underutilised.
Our floating solar projects are engineered to perform in India's diverse water environments — from Gujarat's large irrigation reservoirs to industrial water storage ponds — using marine-grade materials, certified pontoon systems, and advanced mooring designs.
Effective utilisation of water bodies to generate clean energy without occupying valuable land resources — ideal for land-scarce regions.
Floating solar panels reduce water evaporation from reservoirs by up to 30% — aiding water conservation in drought-prone regions of Gujarat and Rajasthan.
Eco-friendly installations that minimise environmental disruption — no land clearing, no excavation, no habitat destruction required.
Durable floating solar systems designed to withstand varying water levels, monsoon flooding, wind loads, and harsh weather conditions across all seasons.
Why Floating Solar Outperforms Land-Based Solar
Floating solar photovoltaic systems deliver measurable performance, environmental, and economic advantages over conventional ground-mounted solar installations.
10–15% Higher Energy Yield
Water naturally cools floating solar panels, keeping module temperatures lower than ground-mounted installations — improving efficiency and generating 10–15% more energy per kWp installed.
Zero Land Requirement
Floating solar systems use the surface of existing water bodies — reservoirs, ponds, canals — freeing valuable agricultural and commercial land for other uses while generating clean energy.
Reduces Evaporation by Up to 30%
Solar panels shading the water surface significantly reduce evaporation from reservoirs — a critical benefit for water-stressed regions across Gujarat, Rajasthan, and Maharashtra.
Suppresses Algae Growth
By reducing sunlight penetration into the water body, floating solar panels inhibit algae and phytoplankton growth — improving water quality in irrigation reservoirs and drinking water sources.
Dual Use with Hydropower
Floating solar systems installed on hydropower reservoir surfaces complement existing hydro generation — using shared grid infrastructure and reducing curtailment during peak solar hours.
Faster Deployment
Floating solar systems require minimal civil work compared to ground-mounted projects — no land clearing, no massive foundation work — enabling faster commissioning timelines.

Everything You Want to Know About Floating Solar (FPV)
A floating solar photovoltaic (FPV) system is a solar power plant where solar panels are mounted on buoyant structures — typically HDPE pontoons — floating on the surface of a water body such as a reservoir, pond, lake, or canal. FPV systems generate clean electricity from solar energy while conserving land and reducing water evaporation. They are particularly valuable in India where both land and water are scarce resources.
Water naturally cools the solar panels in a floating solar system. Solar panels are more efficient at lower temperatures — every 1°C reduction in module temperature increases output by approximately 0.4%. Since floating panels remain cooler than ground-mounted panels (which heat up from reflected radiation), floating solar systems typically generate 10–15% more energy per kWp installed compared to equivalent ground-mounted systems.
Floating solar systems can be installed on reservoirs, irrigation tanks, check dams, farm ponds, hydropower reservoirs, industrial effluent ponds, municipal water bodies, mining pit ponds, and irrigation canals. The key requirements are a minimum water depth (typically 1.5m+), stable water level variation, and access to grid connectivity. Ellence Energy conducts a detailed site feasibility study to confirm suitability before design begins.
Yes. Properly designed floating solar systems use HDPE pontoons — a food-grade, chemically inert plastic — that does not leach chemicals into the water. The shading effect actually improves water quality by suppressing algae growth. All cables and junction boxes are waterproof rated to IP68 standards. Ellence Energy follows MNRE FPV guidelines and conducts environmental assessments as part of every project to ensure zero negative impact on the water body or aquatic life.
Floating solar systems typically have a capital cost 10–20% higher than equivalent ground-mounted installations, primarily due to the additional pontoon, mooring, and marine-grade component costs. However, the higher energy yield (10–15%), land cost savings, and water conservation benefits significantly improve the overall project economics — often resulting in a comparable or better levelised cost of energy (LCOE) compared to ground-mounted solar, especially in land-constrained locations.
Yes. Ellence Energy provides complete support for all floating solar project approvals — including water body usage permissions from the relevant state water resource or irrigation authority, environmental clearances, DISCOM interconnection applications, MNRE compliance documentation, and any local government permits. Our experienced team has navigated these regulatory processes across multiple states in India.
