Bharat Heavy Electricals Limited (BHEL), a government of India undertaking, has issued a tender inviting quotations for the manufacturing and supply of 4,500,000 DWS multi silicon solar wafers with a specification of 157-millimeters.
The bid submission deadline is July 29, 2019. The price bid opening date will be set later for vendors accepted in the technical process. The last date for the delivery of 4,500,000 units of the solar silicon wafers is September 24, 2019.
The technical specifications ask for a 157 mm square diamond wire saw (DWS) multi-crystalline solar silicon wafers. It is used as a raw material in the creation of solar photovoltaic (SPV) cells, which in turn are used in SPV modules. The wafers need to be p-type semiconductors doped with Boron and Gallium. The wafers should adhere to the quality standards and should be free from defects and deformities.
BHEL has listed various criteria that need to be satisfied by the bidding authorities. Primarily, only authentic multi-crystalline silicon wafer manufacturers can apply for this tender. The bidder should have a manufacturing capacity of at least 100 MW per year of in-house PV grade multicrystalline wafer manufacturing capacity. This is a global tender and foreign bidders can also apply.
Moreover, the bidder should have supplied at least 1,000,000 pieces of 156 to 157 mm multi-crystalline high-efficiency solar silicon wafers between January 1, 2016, and June 30, 2019. The wafers should comply with BHEL’s technical specifications as listed in the tender document.
A few days ago, BHEL issued a request for quotation inviting interested parties to submit their applications for the manufacturing and supply of solar cells. The bid submission deadline is July 15, 2019.
It has also floated a tender for the supply, instrumentation, and construction (I&C) of a module cleaning system for 129 MW of solar photovoltaic projects located at Singareni Collieries Company Limited in Telangana.
