3. INTRODUCTION
SOLAR ENERGY 3
SOLAR ENERGY :is radiant light and heat from
the sun that harnessed using a range of
everevolving technologies such as solar
heating,photovoltaics,solar thermal energy.
It is an imporatnat source of renewable
energy and its technologies are broadly
chracterized as either passive solar or active
solar depending on how they capture and
distribute solar energy.

4. What is Solar Energy?
• Originates with the
thermonuclear fusion reactions
occurring in the sun.
• Represents the entire
electromagnetic radiation
(visible light, infrared, ultraviolet,
x-rays, and radio waves).
• Radiant energy from the sun has
powered life on Earth for many
millions of years.

8. Solar Collector
• Glass on outside
• Absorbent on
inside
• Circulating Fluid

9. Concentrating Solar Power (CSP)
•Concentrated solar power a
field of tracking mirrors
focuses sunlight onto a glass
receiver containing water that
can be heated to over 750F.

10. PHOTOVOLTAIC EFFECT
• Converting solar energy to
electrical energy by means of solar
cells =photovoltaic effect
• Photovoltaic panel consist of group
of solar cells
• Solar cells are predominantly made
from silicon,a semiconductor

11. CONVERTING SOLAR ENERGY (LIGHT)INTO ELECTRICITY
•PV panels consist of semiconductors
•PV cells have two types of semiconductors: one
positively charged and one negatively charged.
•When light shines on the semiconductors ,the
junction between these two layers causes an electric
current
•The greater the intensity of light, the greater the flow
of electricity SOLAR ENERGY 11

13. Why you should use solar power
Solar power is good for the environment
Solar power causes less electricity loss
Solar power is a free source of energy

14. SOLAR AIRPORT ; Cochin International
Airport,India:
this Indian airport the
seventh busiest in the
country is the first airport in
the world to run completely
off solar power. In fact it’s
not only 100 percent clean
energy its solar farm
actullay gives back energy to
the electrical grid.

15. SOLAR tindo bus Adelaide ,australia
• In 2013 ,the city of Adelaide in
south Australia put the first fully
solar powered public transit bus
into commission.called the tindo
,which is aboriginal for sun,the
bus can travel 125 miles before
needing to recharge,which is does
at base station at Adelaide central
bus station .it also it provides free
wifi and ac for upto 40
passengers.

16. Tesla solar roof
• Tesla and solar city developed a solar roof
system that integrates the solar cells and
modules inside the structure of the roof
rather than just panels on a roof .
• They are using a high efficiency solar cell
manufactured by Panasonic and covered
wuth a color louver film which allows cells
to blend into the roof while exposing them
to the sun above ,and finally a tempered
glass on top for durability .
• The company says that the typical
homeowener can expect to pay $21.85 per
squre foot for solar roof.
