500kW Floating Solar Banasurasagar, Kerala

Project Details

The project involves fiber steel-based floating structures that are able to adapt to varying reservoir water levels by means of an innovative anchoring system. The conceptual and detailed engineering design was provided by Regen Power

Kerala State with large stretches of water bodies has huge potential for floating photovoltaic systems. Regen power is a consortia member undertaking the design, installation and commissioning of a 500 kWp Grid Interactive Floating Solar Power Plant for Kerala State Electricity Board (KSEB) in the Banasurasagar dam in Wayanad- the first of its kind in India.

The floating solar power plant, was commissioned in late 2017. It generates about 700,000 kWh per year which is fed directly to the grid. Scientific studies have proved that floating solar panels generate higher output due to lower ambient temperature existing on the surface of the waterbody. Apart from this, evaporation of water from the reservoir is minimal as the surface is covered by solar panels.
