2. Energy harvesting is also known as power
harvesting
o Energy harvesting is the process by
which energy is derived from external
sources
EXAMPLES:
oSolar power
oThermal energy
oWind energy etc.

3. WHY SOLAR?

4. It’s free
It’s clean
It’s infinitely
renewable
It can reduce
your utility
costs
It increases
your energy
self-reliance
It comes with
incentives
It can also
increase your
home’s value
It’s
extremely
reliable
?

5. FACT!
It provides approximately 1,000
watts of power that hits Earth
in just two hours is more than
enough to meet current global
energy consumption for an entire
year.

6. Average isolation showing land area (small black dots)required to
replace the world primary energy supply with solar electricity.

SOLAR POWER

8. HOW CAN WE MOST EFFECTIVELY
CAPTURE,CONVERT AND STORE THIS
TREMENDOUS NATURAL
RESOURCE?

9. SOLAR CELLS
Solar cells also known as Solar Photovoltaic cells or Photoelectric cells.
These cells convert the solar radiation into D.C electricity ,which can be
either used as it is or stored in the battery for use at night.
Solar photoelectric cells can be used for domestic and street lighting,
electrification of salty water as well as satellites on outer space.
EXAMPLES:
Calculators
Watches
Satellites
Electric lights
Radios
Highway lighting
Weather stations
Solar cookers
Solar furnace
Solar power plants
Solar water heater

11. SOLAR WATER HEATERS
Solar water heaters can be
installed on the roofs of the houses
It consists of a glass panels with water
pipes
When the sun’s radiation strikes
the panels and the pipes , the sun
rays warms the water for use in
homes and offices.

12. Solar Steam cooking Systems
This system employs a large number of solar concentrators to
trap solar energy to produce steam for use in large scale cooking
in community kitchens.

13. Solar Pump Sets
The solar pump sets operate on power generated using solar photovoltaic cells.
The system is used to lift water from bore or open well or water reservoir for
irrigating the agriculture fields and drinking water purposes

14. SOLAR DRYERS
The device is used for :
drying of agricultural crops
dehydration of fruits and vegetables in food processing industries
production of milk powder and
 casein in dairy industry
seasoning of wood and timber
drying of textile materials in the textile industries

15. SOLAR STILL
The device is used in desalination of brackish of saline water to
get potable water for use in industries , hospitals laboratories ,
homes etc

decathlon in Washington , D.C. with this passive house designed
specifically for the humid and hot subtropical climate.

20. Hope for a better
Solar future…..…..
