objectives
 study the uses of solar energy.
 find more uses of solar energy.
 let people know about the advantages of solar
energy.
 develop the department of the solar energy
 to find solution to problems of solar energy.
Literature review
 Florida Energy Extension
Service (1992) in this
article they discuss the
practical uses of solar
energy. They have talked
about new way of heating
the pools and water by the
solar energy. Also,
powering the electricity
uses in the houses by solar
energy. They have talked
about the benefits and
costs of replacing to solar
energy.
 Stitching TOOL,
Amsterdam (1990) this
article has talked about the
electricity coming from the
sun, and warming water
with solar energy. Also, the
author talked about
different uses and
applications of solar
energy.
Solar energy
 Solar energy is found by
collecting sunlight and
converting it into electricity.
They done it by using solar
panels.
 1,350 W/m2 is the solar
energy coming to Earth
 the amount of energy that
reach the earth is different
depend on (weather cloudy or
sunny- air pollution- Seasons
of the year.
Why solar energy?
 What is the special about it?
 limitless supply
 a free energy but not their
equipments
 more than enough (energy coming
to our world every day 10, 000 times more
than yearly requirement)
 Pollution Free
 flexibility (solar equipment can be
made in many degrees of perfection
and in a wide range of sizes and costs)
Uses of solar energy:
 we can make every electrical device
running by using solar panels
 Examples (cars- space programs)
 Solar water heating:
1. The Efficiency of the device can be
improved by spectrally selective
surfaces .
2. The sunlight heats the water
which is in the tank. Then, a pipe
that faucet the hot water to house
3. can be use for bathing,
dishwashing, and clothes washing
Leaders of solar energy:
 When it was expansive to
buy the coal, people have
found a new thing to
extract energy. So, they
moved to the oil and gas.
 nowadays the demands
and prices have increases
of fossil fuels. So, people
are moving to other
energy recourse.
Solar energy in Saudi Arabia:
 Saudi Arabia reaches between
1900 to 2500 W/m2
 Saudi Arabia is a wealthy
country because of the oil
producing
 it seems that the world will
leave the fossil fuels.
 if we did not move on to solar
energy while we have the
money, we will end up as before
the oil producing
Conclusion
 1,350 W/m2 is the solar energy coming to Earth
 a free energy- more than enough-Pollution Free –flexibility
 There are many uses of solar such as (cars- space
programs- Solar water heating)
