The diagram depicts how a solar-powered
water
pump is used to supply water
to a village. In a nutshell, the system contains an underground well, a solar panel, a pump and a storage tank
.
Initially
, the photovoltaic cells convert sunlight into DC electricity. The produced energy is transmitted to the water
pump. As a result
, the motor inside the pump rotates and creates enough pressure to lift water
from the underground well to the overhead tank
. Eventually, an outlet at the bottom of the container releases water
to the village.
In contrast
, the bore pump is situated below the ground level while
other major components are located above the ground level. Moreover
, the inlet of the water
tank
is placed at the top of the tank
. The solar panel is directed towards the sun to harness more energy. Overall
, this
simple system is sustainable because,
it only consumes renewable energy from the sun's rays.Remove the comma
