2. 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.
What is solar energy ?
 Passive Solar Energy
 Active Solar Energy
 Photovoltaic Solar Power
 Solar Thermal Energy
 Concentrated Solar Power
Types of Solar Energy

3. 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).
Daylighting
Passive Solar Heating
Passive Solar Cooling
Passive Solar Energy

4. 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
Active Solar Space Heating

Daylighting
Passive Solar Heating
Active Solar Heating
Concentrating Solar

Photovoltaics (PV)

6. 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
and solar panel assembly.
 Crystal growing
Wafering
Solar cell production
Solar panel assembly

11. How a Power Tower Works

12. All chemical and radioactive polluting
byproducts of the thermonuclear reactions
remain behind on the sun, while only pure
radiant energy reaches the Earth.
Energy reaching the earth is incredible. By one
calculation, 30 days of sunshine striking the
Earth have the energy equivalent of the total
of all the planet’s fossil fuels, both used and
unused!
Advantages of Solar Energy

13. Disadvantages of Solar Energy
Sun does not shine consistently.
Solar energy is a diffuse source. To harness it, we
must concentrate it into an amount and form that
we can use, such as heat and electricity.
Addressed by approaching the problem through:
Collection
Conversion
Storage.
