PROJECT BRIEF DETAILS

  • 5 MW grid-connected solar photovoltaic power plant is situated in Gurugram, Haryana at the manufacturing facility of Maruti Suzuki Limited
  • The solar PV plant is fixed at an optimum tilt angle and made south facing to maximize power generation
  • The PV modules used for the project are of c-Si type
  • The DC electrical output from the PV modules is fed via cables to string monitor boxes leading to the inverters
  • The inverters convert the DC power to AC power to step it upto 11kV medium grid voltage

PROJECT USP

Kirloskar Brothers Limited (KBL) is a world-class pump manufacturing company with expertise in engineering and manufacturing of systems for fluid management. Established in 1888, KBL is the flagship company of the $2.1 billion Kirloskar Group. KBL, a market leader, provides complete fluid management solutions for large infrastructure projects in the areas of water supply, power plants, irrigation, oil & gas and marine & defence.

CHALLENGES & SOLUTIONS

  • The team had to face several impediments but they overcame each difficulty with dexterity, determination and efficacy.
  • Tackling limited accessibility to the roof for a 30-metre high roof with a slope angle of about 15 degrees
  • Developing a shadow-free roof to accommodate 1500kW of solar PV module installation
  • Appointing a special HSE manager to train the workers during a dearth of skilled labour force and customising special staircases to allow easy access
  • Deploying strict health and safety measures in a remote site with an extreme height
