Solar Collector Operation

  • Step 1: The absorber coating on the inner glass tube absorbs sunlight and converts it into heat.
  • Step 2: Steam forms inside heat pipe which transfers heat rapidly up to the manifold.
  • Step 3: A pump circulates water or heat transfer fluid through the header pipe, carrying heat back to the
  • storage tank. Gradually throughout the day the tank is heated up.<o:p>
