Solar two types of semiconductors, an N-type

Solar
energy is the first energy source to ever be created and the most common
efficient energy source used. This source of energy has been used since the
stone age. To this day solar energy is used to heat houses/buildings or can be
converted into energy to power factories, etc. They can be used to supply
electricity to remote areas, for distilling water in Africa or even open the
possibility of powering satellites in space. Solar energy is the light and heat
rays from the sun that is absorbed by photovoltaic (PV) solar panels that are
made up of silicon solar cells (semiconductors). There are multiple solar cells
in a solar module and the solar modules make the solar panels. A solar cell is
made up of two types of semiconductors, an N-type (negative) and a P-type
(positive). The negatively charged electrons will generate the electric voltage
that can be sent to the channel.

Solar
panels absorb the suns heat and light and convert it to direct current (DC)
energy, the DC electricity moves to an inverter that converts it to alternating
current (AC) electricity, which is then used to power/heat your homes. Solar
energy does not create any pollution and is a renewable energy source, it works
best during the day because the panels cannot trap the light coming from the
sun. Using solar power has a little to no harmful effect on the environment.
Traditional power/heating that we still use for our homes and buildings are
propane, coal, etc. These methods generate lots of carbon dioxide (CO2) that
does not help our global warming issues.

Manufacturing,
transportation, and installation of solar power systems cause emissions but
barely anything in relation to conventional energy sources. As much as solar
energy reduces greenhouse gases, there is always more work to do. We are still
very dependant on fossil fuels for lots of things, but maybe solar energy could
reduce the use of them. Using solar energy is very environmentally friendly,
having it be a renewable energy source means that it is unlimited as long as
the sun shines – according to NASA this will be another 6.5 billion years.  Earths surface receives 120,000 terawatts of
solar radiation which is 20,000 times more power than what is needed to supply
the entire world, the possibilities regarding solar energy are endless. Not
only does using solar energy help our environment but it also helps us humans
from increasing the number of dangerous pollutants in the air. A downside to
having solar panels is you never know what weather you will get. For example,
some factors that might influence the success of your solar panels are where
you live (ex. Florida vs. Canada), time of day (ex. morning, afternoon, night),
and how exposed you are to overcast. 

“One
solar panel that is 250-watt can produce an average of 1kWh per day” (Zientara
“How much electricity does a solar panel produce?” 2017). A large
piece of renewable energy sources is sustainable, meaning that it will not
impair the future generations ability to create new technologies and ways of
living. At the end of the day, sun-powered vitality is practical on the grounds
that it is extremely unlikely we can overconsume. As much as solar panels help
the environment and the health of humans there are technologies improving that
can help us fight the environmental crisis.
