BHEL invites bidders for NTPC’s 25 MW floating solar project in Andhra Pradesh

Bharat Heavy Electricals Limited (BHEL) has issued a tender for the design and supply of floatation platforms for a 25 MW floating solar project. The floating solar project will be installed at the NTPC Limited’s site in Simhadri, Andhra Pradesh. Apart from the design and supply, the scope of work also includes the inclusion of accessories with mooring and anchoring on which the project will be constructed. According to BHEL, nearly 107,700 PV modules will be installed for the project. Interested bidders should be a manufacturer of solar PV floater and should have manufactured and supplied solar PV floaters of a minimum capacity of 100 kW at a single location which were successfully commissioned. The last date for the submission of bids is October 30, 2019.

There are various kinds of floating solar platforms:

Pure-floats: Pure-float configurations use specially designed buoyant bodies which support solar panels directly. These floats have fewer metal parts and are easy to assemble and install. This is the most common floating solar solution worldwide, with several suppliers.

Pontoons and metal frames: Metal structures (frames or trusses) are used to mount solar panels to pontoons, which only provide buoyancy. Thus, there is no need for specially designed floats, and as floats are easy to make they can be easily sourced locally.

Membranes and mats: The entire water surface is simply covered with rubber mats or membranes fixed to floating rings to create a base for solar panel installation.
