About Clique Solar
  We are active in the Solar Thermal segment
  We are specifically focused on off-grid
  Concentrated Solar Thermal (CST):
   Industrial Process Heating (IPH)
   Solar-assisted Cooling
  We are pioneers in the IPH market
   First ARUN installation in Feb 2006
   Even today, the only commercially proven
   technology in the 140-250°C – ‘the IPH sweet spot’
Why Pioneers?
  We have expanded the potential applications of solar
  energy and made it technically & commercially viable
  We have customized the system to the needs of the
  end user
    We have understood and addressed the challenges faced by
    the users in adoption of solar thermal technology
  ARUN® is unique, patented and one-of-its-kind

  Probably the only technology in the solar domain
    that has been 100% indigenously developed
Facts about Clique Solar
  Working in the solar domain since 2004
  MNRE channel partner since Aug 2011
  Promoted by veteran IIT Bombay alumni
  Consortium member of one of India’s first CSP
  power plants coming up near New Delhi
