3. Solar Energy
Solar energy is the energy received by the earth from the
sun.
This energy is in the form of solar radiation, which makes
the production of solar electricity possible.
Solar Energy is clean and renewable source of energy.
Once Solar Panel is installed Solar Energy
can be produced free of charge.

5. Two main types of devices are used to
capture solar energy and convert it into
thermal energy:
• Flat-plate collectors
• Concentrating collectors.

8. GENERATION OF SOLAR POWER
Solar power is the conversion of sunlight into
electricity, either directly using
Photo-voltics (PV)
indirectly using
concentrated solar power(CSP).
Photo-voltics converts light into electric current
using the photoelectric effect.

9. Photo-voltaics
• Converting solar energy directly into
electrical energy.
• Devices used are called solar panels.
• Solar panel is a group of solar cells.
• Solar cells work on the principle of
photoelectric effect.

11. Concentrated Solar Power
CSP is a power generation technology that uses
mirrors or lenses to concentrate the sun’s rays.
That heat a fluid and produce steam.
The steam drives a turbine and generates power
in the same way as conventional power plants.

13. Types of Solar Energy
Passive Solar Energy
Active Solar Energy
Photovoltaic Solar Power
Solar Thermal Energy
Concentrated Solar Power

14. Passive solar Energy
Passive Solar Energy is a method in which solar energy is
harnessed in its direct form without using any mechanical
devices.
Drying Clothes in daylight is an example of using solar
energy passively.
Passive Solar Energy has a few applications
which all of us can use (where ever there is sunlight).
 Day lighting
 Passive Solar Heating
 Passive Solar Cooling

15. Active Solar Energy
The Active Solar Energy employs mechanical or
electrical equipment for functioning and increase
system efficiency. As an example water pumps are
used to circulate water through the active solar energy
water heating system.
Some Applications of Active Solar Energy which can
be very helpful to all of us.
 Active Solar Water Heating
 Active Solar Pool Heating

16. Solar Thermal Energy
Solar Thermal Energy is the heat energy derived from
the incident solar energy (sunlight).
This is used by Solar Heating Panels.

17. Photovoltaic Energy
The Energy generated by incident solar energy (light) into
electricity is termed as Photovoltaic Solar Power.
This is done using Photovoltaic Solar Cells.
Every one of us can get the benefits of the applications of
photovoltaic solar power.
Solar Electricity
Photovoltaic Solar Lighting
Photovoltaic Cooling

18. Concentrated Solar Energy
• Concentrated Solar Power is a branch of Solar Thermal
Energy which is used to generate solar power electricity.
Electricity is produced on a large scale by using this
technology.
• This technology is not in either of our scope. But we can
surely get its benefits from a renewable energy supplier
or green power from the electricity supply company.

19. Uses of Solar Energy
• Heat Your Swimming Pool With Solar Energy
• Solar Energy Can Heat Your Water
• Solar Energy For Battery Charging
• Power Your Home With Solar Energy
• Solar Energy For Cooking
• Solar Energy for Indoor Lighting
• Solar Energy Used For Outdoor Lighting

20. How solar panels are made ?
Solar World manufacturers solar panels entirely in the
USA from raw silicon to completed solar panels. This
process involves four main steps:
Crystal growing
Wafering
Solar cell production
Solar panel assembly

21. Developing Solar Power In
PAKISTAN
In PAKISTAN, about 70% of the population lives in
some 50,000 villages dispersed around the country.
Many of these villages are far from the main
transmission lines of the national grid because of their
relatively small populations.
It is not usually economically viable to connect these
villages to the grid

22. Solar In Pakistan
• Solar energy has great potential in areas of PAKISTAN that
receive high solar radiation throughout the year.
• For e.g. 19 mega Joules of solar energy per square meter is
received everyday.
• The nation wide average is 5.5 kWh/mess/day.
• Enough energy potential for solar energy because there are 250-
300 sunny days per year.
• Continuous cloudy days are rare.

23. Advantages of solar power
development to PAKISTAN
• The power source of the sun is absolutely free.
• The production of solar energy produces no pollution.
• The technological advancements in solar energy systems have
made them extremely cost effective.
• Solar cells are also totally silent

25. Current solar power plants
in PAKISTAN
• SOLAR ENERGY PAKISTAN LTD. (THATTA SINDH)
• DACC LLC SOLAR (SINDH)
• WAH INDUSTRIES LIMITED SOLAR (TAXILA, PUNJAB)
• TEH ACCESS SOLAR (PUNJAB)
• CWE SOLAR (CHOLISTAN)
• BAKHSH ENERGY SOLAR (KASUR)
• ROSHAN POWER SOLAR
• Bahawal pur solar power plant (1000 MW)

26. Future prospects
• Pakistan has a lot of potential especially in
northern Baluchistan. It could also lead to
development in that area. As well as a supply
of electricity in Baluchistan. which is
presently lacking can be established. So the
production of solar power is beneficial for
Baluchistan.
