I
fear the day where we would ran out of resources. I fear the day that we would
have to pay an imaginable price for something like electricity. I fear the day
that I can no longer switch on the television, the air condition or the
computer anytime I want. I fear the day that we would have to live in the dark.
I fear the day where we would look back in our past and regret that we did not
do what we could have done.
There
are numerous ways we can do to save our energy resources. Simple examples are
turning off lights when not in use or use energy efficient light bulbs. We
ought to do these things to prolong our use of the resources we have. We
patronize non-renewable resource, which is why if we do not use them, the
future generations will not be able to enjoy and experience the things we tend
to overlook at present.
But
some of the great discoveries of Alexandre Edmond Becquerel and Russell Ohl
lead to the invention of “solar panel.” Solar panels are made up of
photovoltaic cells, also known as solar cells, which are responsible for
converting photons, or particles of light, into flow of electricity. To be
specific, “Light (photons) striking certain compounds, in particular metals,
causes the surface of the material to emit electrons. Light striking other
compounds causes the material to accept electrons. It is the combination of
these two compounds that can be made use of to cause electrons to flow through
a conductor, and thereby create electricity. This phenomenon is called the
photo-electric effect. Photovoltaic means sunlight converted into a flow of
electrons (electricity).” (Energy Matters)
There
are different types of solar panels for different household and establishments.
Their efficiency differ from one another and how the panels are to be used. First
type would be the monocrystalline silicon or single silicon. According to How
Solar Works, these are the most efficient type of solar panels at present. They
have high silicon content making them more expensive, but less of it would be
needed. The panels turns into electricity most of the sunlight that hits them. These
panels becomes more efficient if the sun directly shines on them at the correct
angle. They have diamond like shape blocks. Second type, polycrystalline
silicon or multi-silicon. These panels have less silicon level making them not
only less expensive but also a bit less efficient. The overall construction
design makes up for the efficiency loss. They have rectangular blocks. Next one
are the solar hot water (thermal) panels. This has nothing to do with
electricity. These panels produce hot water for households or big pools and can
also offer heat and air conditioning.
There
are several benefits that we can get from using solar panels. We all know that the
energy coming from the sun is endless and free and this would save us a lot of
money on our electric bills. It also provides clean energy and does not produce
harmful greenhouse-gas emissions. As there is always two sides of a coin, there
are also disadvantages to take in to consideration in planning to use solar
panels. You would spend relatively high depending on the home, the location,
the size and purpose of the system and what not. The location of the home is
also a factor if it is located in a shade area or the sun does not directly hit
the place. The fact that the sun doesn’t shine brightly for 24 hours a day also
affects the efficiency of the system. Also, the maintenance of the system and its
repair because of natural calamities should also be take in to consideration.
I
think it is time to take the risk and do definite actions to help in reducing
and protecting our remaining resources. It is in our hands to make a move and
start being a change for the better. Why not start save the sun’s energy to save the
whole planet?
