4. INDIA’S
SOLAR
PROFILE….
 India has emerged as
the world's number one,
along with United States,
in annual solar power
generation.
 McKinsey & Company, in
its survey ended in May
2009, has stated that India
has one of the world's
highest solar intensities
with an annual solar
energy yield of 1,700 to
1,900 kilowatt hours per Solar radiation on India
kilowatt peak of the Source: TERI
installed capacity.

5. WHAT IS SOLAR ENERGY?
Photovoltaic
 Energy produced by (solar) panel
the sun.
 Clean , renewable
source of energy.
 Harnessed by solar
collection methods
such as solar cell
 Converted into usable
Sun and
energy such as electrical power
electricity. lines
Set of solar
panels

6. SOLAR CELLS ARE CONVERTERS
OF ENERGY…
Light energy
Solar cells are devices
that take light energy
as input and convert it
into electrical energy
Electrical energy (carried
through wires)
Solar cell - converts light energy to electricity

7. WHAT ARE SOLAR PANELS?
• Solar panels collect
heat energy from
the sun. We call this
heat solar thermal
energy. A simple
example of a solar
panel is a closed box
with a top made of a
transparent material
such as glass or
plastic. In some cases the inside of the box is painted black so
that it absorbs more heat.

8. HOW SOLAR ENERGY
PANEL WORKS..?
 Generate electricity
direct from sunlight..
 2 Main types:
 Single crystal silicon
(Traditional)
• Widespread
• Expensive to manufacture
• Fragile , rigid , thick
 Dye sensitized solar cells
• Thin, lightweight, flexible
• Inexpensive and simple to
manufacture.

9. MANY USES OF SOLAR
ENERGY….
Solar panels to heat air
Solar panels to heat water
Solar electric power generation
Industrial uses
Vehicles running on solar power
Heating living spaces
Practical applications through
solar cookers

10. SOLAR PANELS TO HEAT
AIR…
• A transparent top is
attached to a box. The
box has an inlet pipe for
cool air. The cool air can
be pushed into the box
using a fan. The cool air
moves through the inlet
pipe into the box. Inside
the box the air is
warmed by the heat
energy from the sun
rays.

11. SOLAR PANELS TO HEAT WATER…
• Solar panels that are
designed to heat water
work almost the same
way as ones designed
to heat air.

12. SOLAR ELECTRIC POWER
GENERATION….
• Thanks to the technology of photovoltaic cells,
it is now possible to convert energy from the
sun directly into electricity that can be used in
the home. With solar electric systems, you can
enjoy free, inexhaustible, renewable power
that is environment friendly as well.

13. INDUSTRIAL USES OF SOLAR
POWER…
 Welding helmets.
 Remote systems
 Water circulators
 Self powered sensors

14. VEHICLES ON SOLAR
POWER…
• Solar cars depend
on PV cells to
convert sunlight
into electricity to
drive electric
motors. Unlike solar
thermal energy
which converts
solar energy to
heat, PV cells
directly convert
sunlight into Ned, constructed in 1999 by the South
Australian Solar Car Consortium, can
electricity. speed up to 120 km/h.

15. HEATING LIVING SPACES…..
• A passively heated
home uses about 60-
75% of the solar
energy that hits its
walls and windows.

16. OTHER APPLICATIONS….
 Calculators
 Solar security
system Cam
 Solar watches
 Charging phones

17. STEPS TOWARDS
HARNESSING SOLAR
POWER IN
PUNJAB…..

18. Punjab Energy Development Agency
was formed in Sept. 1991 as a state
nodal agency for promotion and
development of renewable energy
programmes/projects and energy
conservation programme in the state
of Punjab. PEDA is registered as a
Society under the Societies Act of 1860

19. India's first solar power
PLANT OPENS IN PUNJAB…

20. Punjab allots 5
solar power
projects to Punj
LLOYD…

21. Punjab Energy Development Agency
(PEDA) has allotted five solar power
projects to construction major Punj Lloyd…
Atul Punj (chairman of Punj lloyd)

22. PUNJAB GOVERNMENT
to set up solar power plant in collaboration
with
U.S BASED SUNPOWER
CORPORATION
and
ENTERPRISE BUSINESS
SOLUTIONS (EBS)…

23. Collaboration to set up solar power plants….

24. The eco-friendly project will be
set-up under the
INDIAN GOVERNMENT'S
JAWAHARLAL NEHRU NATIONAL
SOLAR MISSION (JNNSM)
programme…

25. THE INSTITUTIONS ARE:
 Central university,
Bhathinda
 Guru Gobind Singh
Educational Trust,
Ludhiana
 Gian Sagar
Medical College,
Banur
 Shivali Public
Schools in Mohali
and Chandigarh.

26. Centre unveils new plan to
boost solar power in
PUNJAB….
• After inaugurating a workshop-cum-exhibition
on ‘Deployment of Solar Thermal Systems in
Northern States’ under UNDP/GEF Solar Water
Heating Project organized by Punjab Energy
Development Agency (PEDA) here Friday, Deepak
Gupta, Secretary, Ministry of New and Renewable
Energy (MNRE), Government of India said that
under the National Solar Mission it was proposed
to declare Chandigarh, Amritsar and New Delhi as
solar cities .

27. PUNJABI UNIVERSITY to tap solar
energy at lower costs…
• Punjabi University’s Department of Physics has
moved a step closer towards converting sunlight
into electrical energy and making it available to
the consumers at a cost nearly one-sixth of the
present cost.
• While inaugurating the newly created Solar
Energy Research Laboratory for running the
project, Vice-Chancellor, Dr Jaspal Singh said that
the effort to covert sunlight and making it
available to the masses at an unimaginably lower
price constitutes a landmark achievement of the
University.

28. Disadvantages of
Solar Energy
High initial capital outlay
Dubious reliability
Availability of sunlight
Polluting materials used in solar panels
The efficiency question

29. CONCLUSION
• The Sun provides a very abundant supply of energy that is available to all of us. This energy from the Sun
is completely under used. If we covered only 4% of the world's desert area with solar panels, this would
supply the same as all the worlds electricity today. Considering how much we rely on fossil fuels this is
far under utilized.
Solar energy from the Sun is available almost anywhere on the planet. Though it is not always available
depending on the obvious weather conditions and time of day. It could drastically change the way we
make energy. Especially combined with other forms of renewable energy such as wind energy.
There is so much potential energy to be gained from using solar energy. The amount of solar energy that
reaches our planets surface is so abundant that in a year it provides around twice as much as we will
ever be able to obtain from all of the Earth's finite resources. These finite resources include coal, oil and
natural gas.
This resource is not just available to businesses and major energy companies. It is also available to the
every day people who would like to utilize energy from the sun in their own backyard. Back yard and
roof top solar panels are being seen more and more all over the world. From professional installation
with manufactured panels to home made with do it yourself installation.
If your looking to move down the do it yourself path, this is by far the easiest, simplest and most
inexpensive way I have found to get started with utilizing the infinite supply of energy from the sun. The
supply is unlimited so it really just depends on how much of it we want to use. Run a small appliance or
two, or produce enough to replace your entire electric bill. It's all up to you.
