This presents a generalized idea of a solar application by an umbrella, which has powered by solar radiation. This umbrella used a solar panel which has a several advantages, and provide a ample surface for mounted the panels, its design to allow the exposure of sunlight and conveniently portable. The solar powered umbrella has uses of providing shades for the user making outdoor experience more enjoyable.

This presentation demonstrates on
the innovative idea to use of solar
energy.
“I’d put my money on the sun and
solar energy. What a source of
power! I hope we don’t have to wait
‘til oil and coal run out before we
tackle that.”

Future Aspect of Solar Energy

3. Solar Energy –a idea
• Solar energy is the ultimate Solar energy is the
ultimate source of energy from millions of years
and it is a renewable energy.
•This energy consists of radiant light and heat
energy from the sun.
•Out of all energy emitted by sun only a small
fraction of energy is absorbed by the earth.
•Just this tiny fraction of the sun’s energy that
hits the earth is enough to meet all our power
needs.
•Using present solar techniques some of the
solar energy reaching the earth is utilized for
generating electricity etc….
•Even then the energy demand met by using
solar energy is very less.

4. Solar Energy –on Earth
The surface receives about 47% of
the total solar energy that reaches
the Earth. Only this amount is
usable

5. Solar Umbrella- Introduction
•The installations of panels can be
modified a umbrella structure.
•In this way it can be installed in any
public places where required shaded
area.
•This umbrella used a solar panel
which has a several advantages, and
provide a ample surface for
mounted the panels, its design to
allow the exposure of sunlight and
conveniently portable.

6. Solar Panels required more area to
installed
Solar Umbrella used area required by
solar panels

7. Solar Umbrella-Design
• Solar umbrella is a generalized idea
of a solar application, which has
powered by solar radiation.
• This umbrella used a solar panel &
provide a ample surface for
mounted the panels
• Its design to allow the exposure of
sunlight and conveniently portable.
• The solar powered umbrella has
providing shades for the user
making outdoor experience more
enjoyable.

8. Solar Umbrella-Panels
• When solar panels are placed in
the sunlight , photons will strike
the surface and emits electrons.
• As a result electron hole pair is
created in the solar cell.
• When external circuit is
connected to the solar cell ,
electrons flow in the circuit and
the current is generated

9. Types of Solar Panels
Monocrystalline –
• Monocrystalline cells are made
from a thin wafer cut from a single
large crystal of silicon.
•The cells are then doped and the
fine current collecting wires printed
on or in the surface of the cell.
•This type of cell takes more energy
to make than any other, and so has a
greater energy payback period,
though this is usually still within five
years
.

10. Polycrystalline -
• Polycrystalline cells are made from
thin wafers of silicon cut from a large
cast billet.
•The billet is not a large single
crystal, but many crystals clumped
together, hence the name
•Polycrystalline cells must have
current Collecting grids printed onto
them
•Polycrystalline cells are usually
slightly less efficient than
monocrystalline cells, but because
they are square, can be fitted into
the rectangular frame of a solar
panel with high space efficiency

11. Amorphous –
• Amorphous thin film panels involve
deposition of very thin films of
silicon or other materials directly
onto a substrate such as glass or
stainless steel.
•This technique produces a cell with
a lower efficiency than the cut wafer
varieties, but has the advantage of
eliminating the need for inter-cell
connections.
•Uni-Solar makes triple-junction ,
nine-layer thin-film amorphous
panels with a much higher efficiency
than the older types.
•The layers of silicon are deposited
directly onto a stainless steel
substrate and are then coated in a
flexible plastic protective layer.
