Question

What are the main components of flat plate solar collector, explain the function of each?

Answer 1

Answer:

In order to maximise efficiency, a solar flat plate collector normally consists of a big heat-absorbing plate, commonly made of copper or aluminium because they are both good heat conductors, which have been painted or chemically etched black to absorb as much solar light as possible.

Explanation:

• Several parallel copper pipes or tubes, known as risers, that run lengthwise across this blackened heat-absorbing surface hold the heat-transfer fluid, usually water.
• In order to achieve the greatest possible surface contact and heat transfer, these copper pipes are directly glued, soldered, or brazed to the absorber plate.
• The temperature of the absorbent surface rises as a result of solar heating.
• The fluid moving inside the copper pipes is heated as the plate gets hotter, and this heat is subsequently absorbed by the fluid and utilised by the home.

This is the functioning of the flat solar collector.
