How does solar hot water work?
Active solar hot water systems use circulating pumps to keep the water heated as a it pumps through the system, whereas passive systems rely on heated pipes to keep the water heated as it moves through your home.
How does an active water system work?
With an active system, it will either use the sunlight stored by the solar collector panel or a heat exchanger to heat the water as it’s moving through the system. Thanks to the circulating pump, an active system is able to keep the water heated during its motion, making it more reliable than an passive system, which has to store, collect and heat the water in the tank unit before moving. Since there is no pump in a passive system, these units are often coupled together, using thermosyphon technology to both collect the solar power and heat the water in the same place.
What is an evacuated tube hot water system?
Evacuated tube collectors: These work similarly to flat-plate collector hot water systems. The difference is that this model collects sunlight using a series of glass tubes that have a vacuum seal. This allows for the efficient transferral of solar energy. As such, evacuated tube collector hot water systems are widely considered to be the most effective, however they are also the most expensive.

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 solar collector work?
Sunshine (or “solar radiation”) passes through a collector’s glass covering and strikes a component called an absorber plate, which has a coating designed to capture solar energy and convert it to heat. This generated heat is transferred to a “transfer fluid” (either antifreeze or potable water) contained in small pipes in the plate.
