Why are flat mirrors used in solar panels?
This has the advantage that flat mirrors are much cheaper to produce that parabolic mirrors, and also allows for a greater density of reflectors in the array, allowing more of the sunlight to be used.
How are mirrors used to reflect the sun’s heat?
Central Receiver Systems. Central receivers (or power towers) use thousands of individual sun-tracking mir- rors called “heliostats” to reflect solar energy onto a receiver located on top of a tall tower. The receiver collects the sun’s heat in a heat-transfer fluid (molten salt) that flows through the receiver.
