What
is solar power? Why is it so
important?
Sun,
the brightest of all celestial bodies, emits a radiant
energy through its rays. The sun’s rays are necessarily
electromagnetic waves that give us the radiant energy.
This radiant energy is captured and machinated to
generate into electricity or mechanical power and even
chemical power and is known as what we call solar power.
The idea of how does solar power work
is undoubtedly an amazing one and definitely needs a
close consideration. In this article we will ponder on
some obvious aspects of solar
power.
How
does solar power work?
To
realize the regeneration, use and application of solar
power, we definitely need to realize this solar power as
a viable resource. As stated above let us discuss in
detail as to what at all this solar energy is and how it
can be regenerated into desirable and applicable forms
of power. The sun’s rays are made up of electromagnetic
waves that hit the earth’s upper atmosphere.
Approximately seventy percent of this radiation is
absorbed by the earth like the clouds, water bodies and
the landmasses. The remaining thirty percent is
reflected back to the space. The absorbed radiation
heats the landmasses, water bodies and the atmosphere
that fences the earth. This is called radiative heating
of the earth’s atmosphere. And the heat produced due to
direct sunlight causes solar radiation and the heat
produced is called radiant heat. This solar radiation
accounts for about 99 percent of the usable flux of the
renewable energy on earth. Now how does solar power work
in a particular field economically and practically
depends on how efficiently this solar radiation is being
tailored by the solar power technologies at that very
practical end.
The
application of solar radiation, that is, how does
solar power work majorly depends on the variation
of the requirements and various techniques have been
invented for the specialized deployment of different
forms of solar radiation. Broadly considering, solar
power technologies can be divided in to two streams,
namely active solar power technology and passive solar
power technology. Active solar power technologies make
use of the solar energy directly in the concerned
practical end like photovoltaic cells to convert
sunlight into heat, pumps to convert sunlight into
mechanical power and even fans to convert solar energy
into electrical power. On the other hand passive solar
technology emphasizes on the direct use of sunlight like
designing buildings with well-lit and well-circulated
spaces, citing a building optimally to the sun
etc.
Thus
it is very clear now that passive solar technologies
greatly discourage and actually minimize the use of
alternate power resources and active solar technologies
opt for more and more supply of solar power. Thus solar
power has justly become an integral part and parcel of
our lives. The various fields of application of solar
technologies, active or passive are domestic front,
urban planning and architecture, agriculture (that
include horticulture and greenhouse), solar lighting,
solar heating, ventilation and cooling, disinfection and
desalination, cooking, electricity and the list goes on.
Solar power, therefore, has tremendous influence on the
modern earth along with some disadvantages as
well.
Solar
energy: advantages and
disadvantages
To
empathize on the fact that how does solar power work, we
need to scrutinize each and every advantage and
disadvantage of this high tech application of modern
science. The main advantage of solar power is that it is
an inexhaustible source of power or fuel. Secondly, solar
energy is absolutely pollution free and none of the
solar power technologies produces any air pollutants or
greenhouse gases like the other conventional power
plants. Solar power is such an amazing supplement of
alternate resources that even cars and satellites are
being run with this versatile and specialized fuel!
However, the fact that a very strong sunlight and
therefore areas with very strong and consistent sunlight
are required for the solar power technology to work
limits the use of this technology to only some few parts
of the world. A diffused source would produce a low
energy which will not be economic to the expensive
set-up. Developments are happening though to overcome
these limitations so that solar power can be used
without any dilemma by the environ-conscious people
worldwide.
Solar
power will surely work for you and make you save a lot
of money on your electricity bills besides cleaning up
the environment too. So its time you considered
installing a home solar power system. The best way to
install the system is with the help of a guide that hand
holds you and shows you step by step where to set it up,
how to install it, how to wire the system, where to get
parts from cheaply, where to get batteries free and also
the safety precautions that you must always follow. Such
a guide will let you install the solar power system
quickly and safely.
