What is the difference between a solar hot water collector and a solar electricity panel?
Solar hot water collectors use heat from the sun and/or air to directly heat water. Solar photovoltaic (PV) electricity panels use sunlight to generate direct current which can then be converted to alternating current and used within the home or to feed power back to the electricity grid. Solar hot water collectors can’t be connected to the electricity grid and solar PV panels can’t be used to heat water – they are different forms of technology and are not linked.
