The plant was inaugurated at the Dwarka Sector 21 Metro station.
An official of Delhi Metro Rail Corporation (DMRC) said the power produced from this plant will meet the power requirements of the DMRC at this station.
"The Roof Top Solar Power Plant is expected to start by end of July," he added.
It has a power generating capacity of 500 kWp.
The Delhi Metro is the first Metro system in the country to install such plants at its Metro stations.
The official added a power purchase agreement (PPA) regarding the installation of the plant was signed last Feb between the DMRC and a multinational firm that is engaged in installation of solar power plants.
This is the largest roof top plant with such capacity in Delhi National Capital Region under the RESCO model. Under this model, the DMRC will pay for the units generated by the plant and the capital investment shall be provided by the developer.
