What is the difference between a direct and indirect solar system?

In an indirect system, solar energy is collected and held in a special antifreeze fluid. The antifreeze is circulated into your hot water storage tank, which heats water for use in your home. By comparison, in a direct setup, your water gets heat directly from the sun, rather than being collected in a transfer fluid first.

How does a direct solar hot water system function?

A direct solar hot water system functions by cycling potable water through your collectors, where it is heated by the sun and moves throughout your home. These systems work effectively in warm climates because heated water moving through pipes has less chance of losing energy when surrounded by warm air.
