Challenges

  • Height of the building
  • No access to the rooftop
  • Slanted shape of the rooftop
  • High wind speed
  • The dome-shaped metal roof of the brewery at Alwar is 20 meters high and at each end of the roof is a sharp curve slanting towards the ground. The daunting task was to install solar modules at the height of 20 meters on a curvy roof, where it is extremely difficult for people to even stand properly. This problem was further compounded by high wind speeds, due to the high altitude, and the lack of access to the rooftop.

Solution

Safety first: While working at heights and on Dome-Shaped Metal Roofs

Engineers from CleanMax enabled access to the roof, without compromising the safety of the existing infrastructure. They established an access route to the rooftop by setting up a ladder through which a safety line with harnesses and ropes was set around the dome. The wires with anchor points were designed to hold project staff and save them from falling from the rooftop. A walkway was created to enable easy movement across the roof.

The workers at the site were given special training at the beginning of each day, to highlight the risks and precautions to be taken for the day’s activities. To ensure maximum safety, a dedicated resource monitored the wires and ropes for their strength at all times. This additional safety measure ensured prompt action in case of emergency.

Highlights

  • Heavyweight solar modules installed at the height of 20m on a curved roof
  • Special training provided to workers each day to ensure maximum safety
  • Project completed in a record 60 days
  • Despite the mammoth challenge, the turnkey project was completed in record 60 days after the PPA was signed and the plant was commissioned in March 2016. The “safety first” approach enabled a swift and easy installation.
