In an indirect solar system, the panel is filled with a glycol (anti-freeze) solution and this is pumped through a heat exchanger fitted in the storage cylinder. Through this system the potable water in the storage cylinder is separated from the fluid in the solar panels.
Because of the glycol (anti-freeze) solution in the system, there is no risk of panels freezing and bursting in inclement weather. An added advantage is that the panels can be operated at nil to low pressures. This system is, however, more costly than that of a direct system.
