Heliostats are tracking mirrors that reflect solar energy onto a fixed target.
Concentrated solar water heater.
The cold water intake from the house attaches to one end and the hot water supply to the other end.
The receiver contains a heat transfer fluid which can consist of water steam or molten salt.
Concentrating solar collectors use shaped mirrors or lens to provide higher temperatures that flat plate collectors.
Heat transfer fluid flowing through the receiver tube absorbs the thermal energy.
Parabolic trough systems concentrate solar radiation specifically direct normal insola dni onto a receiver tube located along the focal line of a single axis tracking parabolically curved trough like reflector.
