The flat-plate solar collectors are probably the most fundamental and most studied technology for solar-powered domestic hot water systems. The Sun heats a dark flat surface, which collects as much energy as possible, and then the energy is transferred to water, air, or other fluid for further use.
These are the main components of a typical flat-plate solar collector:
Black surface - absorbent of the incident solar energy
Glazing cover - a transparent layer that transmits radiation to the absorber, but prevents radiative and convective heat loss from the surface
Tubes containing heating fluid to transfer the heat from the collector
Support structure to protect the components and hold them in place
Insulation covering sides and bottom of the collector to reduce heat losses
The flat-plate systems normally operate and reach the maximum efficiency within the temperature range from 30 to 80 oC (Kalogirou, 2009), however, some new types of collectors that employ vacuum insulation can achieve higher temperatures (up to 100 oC). Due to the introduction of selective coatings, the stagnant fluid temperature in flat-plate collectors has been shown to reach 200 oC.

Great video, though I wish you can do 1 totally in English.

Can't we install a flat plate collector without using transparent cover?
Even the collector can collect the radiation without it. Isn't it?

Transparent cover kyo lagate hai

[@FreshersJobAlertOfficial]

Transparent nahi hoga toh sunlight kayseh enter karenga..So, transparent cover is used for entering sunlight.
