Question

What is the material used in flat plate collector?​

Answer 1

Flat plate collector. A flat plate collector (FPC) is made of fluid tubes (filled with flowing HTF) connected to a darkened (high absorptivity) flat plate absorber that collects the sunlight and transfers the heat energy to the tubes.

Answer 2

A flat-plate collector (FPC) is a device to collect solar energy and transform it into thermal energy (low-grade energy) by using water as a working fluid. It is a heart of solar thermal devices that has many applications in a medium temperature range ≅100 °C from domestic to preheating to industrial sectors.
