Solar Power Debut
BLW, in Varanasi, introduced India's first removable solar panels between railway tracks. This initiative aims to promote renewable energy. The panels,
mounted using an indigenous technique, are designed to be easily removed during track maintenance. This project could be scaled across Indian Railways’ entire network, especially in yard lines.
Energy Generation Details
The project, which has a 70-meter track length, includes 28 solar panels. It is expected to generate 67 units of electricity daily, boasting a 15-kilowatt peak (KWP) capacity. The power density is 220 KWp per km, and the energy density is 880 units per km per day. This setup could generate 3.21 lakh units annually per km.
Panel Specifications
Each solar panel measures 2,278 mm by 1,133 mm and weighs 31.83 kg. These panels have a module efficiency of 21.31 percent. They use 144 half-cut mono-crystalline PERC bifacial cells, an IP68 junction box, and a maximum system voltage of 1,500 V. The panels are fixed on rubber pads with epoxy adhesive to endure train vibrations.
Sustainability Push
The Ministry of Railways described the project as a “historic first,” a step towards sustainable rail transport. BLW already operates rooftop solar plants. The new initiative is expected to complement existing green energy efforts, showing a combined focus on renewable energy, freight growth, and infrastructure modernization by the Indian Railways.
Future Potential
The project has the potential for wider adoption across the Indian Railways' 1.2 lakh km network. This is especially true for yard lines where additional land isn't required. Officials said the project may play a key role in the Indian Railways' endeavor to reduce carbon footprint and adopt sustainable practices across its operations.
