Solar
power refers to the power supplied by the sun to the earth. All organic
lifeforms on Earth use this energy. Without it, life could not sustain on this
planet. Solar Power comes to this planet mostly in the form of Light and Heat
energy. This power can be harnessed and stored as energy for future use. The
energy obtained is usually converted to electrical form by use of
photo-electric effect.

 

The
sun is made up of a burning ball of gaseous mixture of Helium and Hydrogen.
Sub-Atomic fusion takes place and a massive amount of energy is created every
instant. Only a small portion of it reaches us. We can only use convert 15% of
the power to usable energy.

INSERT HISTORY AND PRODUCTION of PHOTO ELECTRIC EFFECT

The
production of solar energy began in 1953 in the USA where solar plates were
used to generate electric energy to supply nearby households. This became a
commercial success for its cheap production cost.

 

The
impending need of energy in this world is ever-expanding. Mankind has made
ground-breaking achievements and hopes for a future where technology
flourishes. To this need, power and energy are required. The need of energy
used in our daily lives doubles after every 5 years. The co-existing method of
energy production may run out in the near future. Coal, Gas, Oil and other
fossil fuel are extracted more quickly than ever before. At this rate, all
stored energy on our planet will be exhausted by the next 60-70 years.
Renewable energy like Water, Air and Solar can come to the rescue. We can use
solar energy as an alternate and non-exhausting source of energy.

 

Production
of energy is used as a parameter to determine the development of a country.
Bangladesh is lagging behind in huge proportions. We have to import energy from
nearby countries. Solar power can help provide a useful change. Blackouts in
the city can be prevented if people generate energy from solar power. Solar
plates can be set up at the roofs of apartments. In remote areas, generation of
energy from solar power can be a business opening. Many villages don’t have
access to electricity and a lot of them get for only a few hours per day.
Irrigation by water pumps is also hampered. In such cases, solar power will
help establish usable energy.
