The solar inverters to be supplied by ABB for the project include TRIO and PVI series that vary 5kW to 50kW in power based on the size of the station. The inverters will be part of the solar installations being set up by Azure Power.

The installations of ABB, which has established solar inverter manufacturing facility in India, account for 40% of the country's solar installations.

Azure Power chairman and CEO Inderpreet Wadhwa said: "Azure Power has superior rooftop solar power solutions for infrastructure, commercial and industrial customers in cities across India to lower their energy costs and meet their greenhouse gas (GHG) emission reduction targets.

"We are pleased to partner with ABB and Indian Railways in reducing GHG emissions through deployment of solar energy at railway stations across India."

The Indian Railways, which claims to be one of the largest and most used railway corridors in the world, carries over 8bn passengers every year.

The Indian Railways operates over 12500 trains and 23m passengers per day. The firm functions over 8000 stations across the country. The railways currently has renewable energy generation capacity of 36MW and focuses on increasing to 1000MW.

Recently, ABB's reached a milestone of 5GW of solar inverters installed in India. Its solar inverters are installed in the world's first fully solar powered airport in Kochi.
