This talks about the energy from the Sun being converted to Electricity!! It show the process and the facts along it! Go ahead and find out more!

Grade 6

3. What is it?
How does it work?
• Solar Energy is a renewable source of energy.
• Solar Cells use the Sun’s light energy,
transforms it into electrical energy and then it
is send to homes.

5. Solar Energy- renewable or
non-renewable?
• Solar Energy is a renewable source of energy.
• It is a natural source of energy.
• It is not depletable.
• It is unlimited.
• It can be replenished.

6. The history of the Solar energy source?
• In 1912, Shuman built the first solar energy
power station in Egypt.
• Shuman’s power station was delivering 45-52
kilowatts. While it is very less comparing to
today’s delivery of kilowatts but at that time it
was a notable event in history of Solar Energy.
• Shuman found the way to provide energy by
Solar Energy as the oil and coal was all used
up.

7. Where is it found?
• Solar Energy is found everywhere in the world.
• The rooftops of residential and commercial
buildings are having Solar Panels and can be a
source of solar energy.
• Solar Energy is also used to power traffic lights.
• It is present everywhere and all the time- except
on a rainy day or in the night when Sun is not
present, but it is present in other hemisphere.

8. How is the Solar energy recovered?
• Solar Energy is recovered by solar photo
voltaic cells as it generates electric power
using Solar cells.
• If Energy is not captured using these cells then
Sun’s light energy will not be captured.

9. How is the Solar energy stored once it
is recovered?
• The Energy can be stored with the help of:
 Battery Banks (storage device)
 Connect to the Grid (Connecting the energy to
the grid directly and sending it to other needy
areas)
• Most of the Solar Panels are connected to the
grid directly.
• A lot of building and residential roof tops have
solar panels that help generate electrical energy
and is used for power lights etc.

10. How is the Solar energy used today?
• Solar Energy is used to power:
 Homes
 City office and buildings, street lights.
 Electrical points and connected to the main
Grid.
• It is used as an alternative to coal energy.
• The usage of Solar energy is increasing with lot of
residential and office buildings having solar
panels on their roof tops.

11. Is the energy source efficient?
• Solar Cells convert only 20% of Sun’s rays to
Electricity.
• Solar Energy has low conversion of efficiency.

12. Advantages of Solar energy
• It is Re-usable and natural.
• Does not cause harm to the environment.
• It produces power without waste and
emissions i.e. it is pollution free.
• Energy from Solar panels is infinite and not
depleting like coal.
• Except the initial set up and Solar panel costs,
the running costs are zero.

13. Disadvantages
• Solar Panels are very expensive.
• The amount of energy depends on the
intensity of light and the weather. Hence, it is
little unpredictable and cannot be trusted for
critical functions.

14. The environmental impact
• Solar Energy uses extensive land. It destroys
habitat.
• To Generate Solar Energy, there are many
hazardous materials used.
• It generates clean electricity without toxic
pollution or emissions.
• Overall, very minimum impact and very
environmentally friendly.

15. Other Interesting facts about the Solar
energy
• 170 thousand billion watts hits the Earth every
moment from the Sun.
• Vitamin D is created in our body by Solar Energy.
• The first Solar Power Plant was built in 1912.
• Government offers tax incentives to install solar
panels on your home to encourage consumption
of Solar energy.
• Today’s 70% of energy is generated by coal and
non renewables while solar constitutes around
<5% of World Energy needs.

16. The future of Solar energy
The future is very bright because :
• Most of the people are wanting Solar Energy as it is a
one time investment with no running costs.
• There are Tax Incentives announced by the government
to increase more of solar energy.
• People are getting a substitute of coal and Solar is a
cheaper source.
• Newer technologies in solar panels have reduced the
overall costs of solar energy.
• The use of Solar energy and other renewables will
increase to substitute the costly and not so clean
thermal/coal energy.
