6. A solar Stirling
Engine (or Hot Air
Engine) takes
advantage of the fact
that concentrated
sunlight is a fantastic
heat source, and as
such can be used to
generate electricity
more efficiently than
photovoltaic solar
panels.
OVERVIEW OF STIRLING ENGINE
7. What basically Stirling Engine
is?
Reciprocating engine.
External combustion (get heat from external source).
Converts heat energy into mechanical power by
alternately compressing and expanding a fixed quantity
of the working fluid at different temperatures.
Work on both conventional and non conventional sources
Efficient , clean & silent
8. The Stirling engine was developed in 1816 by Robert Stirling
in order to offer an alternative to the frequently explosive
early steam engines. Basically a closed cylinder containing a
piston and helium, nitrogen or hydrogen gas is heated at one
end by concentrated sunlight, and cooled at the other end by
air or water. As the gas expands and cools with the
movement of the piston, a generator can be driven to produce
electricity. (If the engine is run in reverse then it produces a
cooling effect acting as a 'Stirling cooler'

11. A parabolic dish is used to get heat from
the sun, and for reflection of sun light the
aluminum foil is used there.
The size of the parabolic collector is
depending upon the power of stirling
engine.
Then a stirling engine is placed at the
focal point of the solar collector.
The electric generator is also coupled
with the stirling engine.
When cylinder of engine get hot by the
sun heat then it starts working thus power
produces by the generator.

13. Advantages of solar stirling
engine
The silence of operation.
Can run on any available heat source.
Supplying heat from continuous combustion process.
Some cases, allows the use of lightweight cylinders.
The engine mechanisms are simple in many ways.
Stirling engines are best for constant speed purpose.
Their maintenance cost is very low.
14. Disadvantages of solar
stirling engine
The initial cost of the engine
It needs to warm up.
The problems of sealing.
Design complexity.
Some stirling engines are large for the amount of power that
they produce.
Losses increased due to regenerator, heater and cooler.
15. THE SCOPE OF SOLAR STIRLING TECHNOLOGY
As we know that today the huge amount of
world’s power is produced by the fossil fuels
and that is also threaten to the environment.
Even the prices of power are increasing day
by day due oil crises and also the trend of
load shedding has been started.
So now the trend should be changed the
technology has to be switched off instead of
renewable energy resources.
The solar stirling technology is best option to
produce maximum power to overcome
energy crises.
The capital cost is high of this technology but
the source of energy is free till the universe
ends.
