They will also have to provide operation and maintenance support for the next five years from the date of trial run of all rooftop SPV projects.

The solar PV system shall use crystalline modules conforming to the latest edition of IEC 61215/IS 14286. The capacity of each of the solar modules design should not be less than 240Wp.

The tender stipulates suitable arrangement for metering of the output from each solar PV feeder for rooftop capacity of more than 30 KW.  For rooftops where metering is not provided, the inverter must be capable of measuring/displaying the electrical parameters. Integration with available nearest/feasible suitable grid source supply also comes in the developer’s scope.  All integration is to be done at 415V level.
