Can i install a solar water heating system if i live in an area that experiences frost?

In areas where the temperature drops to below 4° or where there is frost, an indirect solar water heating system must be installed.  In an indirect system, a solution of glycol, anti-freeze and corrosion inhibitors flows through the collector.  This prevents freezing and cracking of the collector.  A heat exchanger heats the water in the solar storage tank.
