These thermal panels are designed in the same way as those on the market: a solar collector containing a heat transfer fluid is sandwiched between an insulator and a sheet of glass. In this case, we will use the grill you find at the back of a fridge for the solar collector.. And we will use the door of the fridge as the insulator. The glass is from old double glazed windows. You will find many fridges in landfills or recycling areas, and double-glazing windows at many glaziers.
