Overview:
The World has great shortage of energy. The main sources of producing
energy are oil, gas, coal etc.
However, these sources are too much expensive and needs great efforts,
resources to be utilized for industrial as well as domestic purposes.
Sun is the main source of energy. it releases energy at a mass- The rate
of conversion of energy is 4.26 million metric tons per second, which
produce 3.846x10 26 W.
In Pakistan shortage of energy is the main problem. Industries and
household requirements are several times greater than energy production
by Hydroelectric mechanism.
Pakistan is seeking alternatives for production of energy. Solar Panels
are one of the cheap sources of production of energy.
Solar Photovaltaic was discovered back in 1839 by French scientist
Edmond Becquerel. Over the course of the next 100 years, many
discoveries and inventions were made and by 1954, Daryle Chapin, Gerald
Pearson and Calvin Fuller were the first to design the first silicon
photovoltaic cell which was the precursor of all silicon cells today.
Over the next few decades, solar power technology continued to develop.
Photovoltaic research and development discovered new material, cell
designs and novel approaches to solar material and product development.
Now a days, solar panels are available all over world for converting
solar energy to electricity. In Pakistan, they are widely used in areas
Where the hydroelectric power has not reached, or to cope with the
effects of load shedding in urban areas.
Today we are going to design assemble and demonstrate a model of a fan
run by a solar panel.
