What's the difference between a solar PV system and a solar hot water system? What are your sustainable water heating options?

  • A solar PV system comprises of solar panels, an inverter, and wiring. Together, these components make solar power that can be used by your appliances and lights in the form of alternating current (AC).
  • A solar hot water system can be a variety of things, usually a system that uses roof collectors (flat panel or evacuated tube) to heat water tanks and sometimes an instant hot water unit that boosts supply by gas or electricity if needed.

Both options are great solutions for reducing your energy bills and your carbon emissions, and there are many rebates and payments available to make investing in your sustainable future possible.

Although not technically a solar powered solution, heat pumps are also classed as 'environmentally friendly' and if you're looking at solar power to heat your wataer you may also want to look at this option. Heat pumps heat water efficiently by using the heat energy in the air and don't need direct sunlight. This is an especially good option if you don't have a well-positioned roof for solar panels or solar hot water collectors as the panels do need to be exposed to a significant amount of sunlight to be effective.
