SOLAR PV
SOLAR
PHOTOVOLTAIC
The conversion of sunlight into electricity with the
use of solar cells is called solar photovoltaic, or solar pv for
short.
The technology is simpler than it would
seem.
The
photons from the sunlight are attracted to the solar pv panels
and interact with the electrons speeding them up and creating
energy.
The demand for this type of technology is on the
rise as globally, people are looking for clean energy sources.
What you see when
looking at the roof of a home or building that utilizes solar photovoltaic energy is a dark
panel.
The solar cells are organized together on a board
that is protected from the environment with a glass sheet. The cells are electrically connected to form a
solar photovoltaic module or what is commonly known as a solar
panel.
A single module can create enough energy to power
an emergency phone; however, to power a single home or an entire power plant the solar pv
modules must be arranged in arrays.
Essentially, solar photovoltaic cells are electrically linked to create a module
and the modules are electrically linked to create solar pv
arrays.

These arrays or series of panels are placed on
the roof of a home or within a solar field to face the sun and often follow the sun to
utilize as much of the solar photons as possible.
The electricity generated from the solar pv
arrays can power a home, assist in powering a home or can be collected and distributed
through a power plant.

Although the technology is readily available and
solar photovoltaic panels are being purchased and installed in locations around the globe the
cost is still significantly higher than the cost of conventional grid electricity, making it
continue to be on the wish list of many.
This wish list may soon be fulfilled for people
in Japan, Germany and the United States.
The significant financial incentives to use solar
pv in Japan and in Germany has triggered the increase in demand and thus the growth in
production.
In the United States the incentives to utilize
natural and renewable energy sources such as solar photovoltaic includes tax
breaks.
In addition, Australia and Israel also offer
financial incentives such as feed-in tariffs for solar generated
electricity.
On a global level the use of solar photovoltaic for
electricity has a long way to go; however, great strides are being made and the speed in
which this occurs is increasing.
The three leading countries in using solar pv
are: Germany, Japan and the USA and represent nearly 90% of the
usage.
This may soon change as China is developing a
solar pv production facility and is expected to have a peak capacity of about 1,500 mega
watts.
The technology continues to grow with solar
plants and farms being created around the world and exploration of the advances in solar
photovoltaic continues.
Currently, there is a 45 mile stretch of roadway
in Idaho that is being used to test the possibilities of using roadways for solar power by
installing the modules in the road since rural roadways often have unobstructed access to the
sun.
Soon, harnessing the sun will be the standard for
electricity generation.
