State-owned engineering major Bharat Heavy Electricals Limited—which also provides solar EPC services—has invited bids for manufacturing and supply of multicrystalline PV modules with peak power output of minimum 330 W.
A total of 231,200 quantities are to be delivered by February 10, 2020, for BHEL’s 100 MW project at Raghanesda Solar Park and 75 MW project (Phase II) at Dhuvaran Gas Based Power Station in the state of Gujarat.
To be eligible, the bidder must have module manufacturing capacity of 300 MW/annum. Further, it must have cumulatively supplied 300 Wp and above wattage crystalline silicon PV modules for a minimum capacity of 100 MW in India. Out of this, minimum 10 MW PV modules must have been supplied to at least one solar power plant of minimum 10 MW capacity.
The modules must be designed with 72 numbers of cells in 12×6 series configuration and be suitable for 1500V DC system voltage application. These shall have efficiency of 15% minimum, fill factor of 0.75 minimum and power temperature coefficient of -0.43% or better.
Further, the modules shall be able to perform satisfactorily in relative humidity up to 85% with temperature between -40°C to +85°C and shall withstand adverse climatic conditions, such as high-speed wind with dust/sand particles and saline climatic/soil conditions.
PV modules must be warranted for their peak output capacity (watts), which should not be less than 90% at the end of 10 years and not less than 80% at the end of 25 years from the completion of the trial run. Degradation of PV module for first year shall be limited to 2.5%.
The PV module power output warranty as per the technical specification shall be insured and backed up through an insurance policy by a reputed insurance company which will cover against the PV module power output warranty in case of insolvency or bankruptcy of the PV module manufacturer.
BHEL requires first lot delivery of 25 MW commencing from 4 weeks from the date of manufacturing clearance or manufacture quality plan approval by BHEL, whichever is later, and subsequently 25 MW within every 4 weeks.
The delivery schedule will be the same for all vendors even in case of splitting of the quantity among more than one vendor.
