CEL tenders 36,500 quantities of 75 W solar modules


Government-owned Central Electronics Limited has invited bids for supply of 75 Wp solar modules based on crystalline silicon technology.

To be eligible, the bidder must have installed module manufacturing capacity of minimum 5 MWp, and supplied 50 Wp to 100 Wp modules with minimum 2 MWp in last one year (July 1, 2018 to June 30, 2019).

The modules must be made into 9×4 arrays using 36 cells each. Under standard test conditions, these should give nominal power output of 75 W with a module efficiency of 14.20%.

The solar panel glass should be a minimum 3.2mm thick with an anodized aluminum frame having an anodizing thickness of more than 15 μm.

The modules must measure 800x660x35 mm3 in dimensions, weighing around 6 kg. These should be BIS or IEC 61215 and IEC 61730 certified.

Delivery and warranty

Delivery is to be made in lots of 5000 to 10,000 modules per month as per the requirement of CEL, which will be communicated at the start of each month. The entire supply has to be completed by December 31, 2019.

The producer must provide a warranty against manufacturing defects for a period of 10 years from the date of supply. The modules should also be warranted for 90% power output after a period of 10 years and 80% power output after a period of 25 years.
