absorbing plate
Black metallic sheet that harnesses heat from solar
radiation and transfers it to the coolant fluid.
insulation
Material placed on the back side of the collector to
reduce heat loss.
flow tube
Tube containing a coolant (water, air) that is used to
recover and carry heat to the absorbing plate.

7. frame
Collector’s insulating case that is enclosed in glass.
coolant inlet
Cold coolant flows into the circulation tubes to absorb
the solar energy trapped by the collector.
coolant outlet
The coolant exits the collector at high temperature (up to
about 175°F) and is stored or used immediately.

8. Solar Photovoltaic (PV)
Using solar photovoltaic, sunlight is
converted into electricity.
Solar photovoltaic uses photovoltaic
(PV) cells usually in the form of
panels,
also called solar panels
Solar Energy - How it works
Using the energy which is
Collected from the sunlight
it do many things.
