The document discusses solar Stirling engines, which can convert solar energy to mechanical energy. A Stirling engine uses heat from an external source to power its operation. It was invented in 1816 and can achieve near-maximum theoretical efficiency. For solar applications, the heat source is solar energy collected via a dish collector. It then works by using pressure changes from heated gas to power pistons or generate electricity. Some benefits are its efficiency, quiet operation, and ability to provide power independent of transmission lines. It has potential applications for electricity generation, industries, homes, agriculture, and rural electrification. However, it also faces challenges in manufacturing and competing with established solar technologies.

2. INTRODUCTION
• Limited availability of petroleum products,
electricity in rural areas
• Limitation of fossil fuels
• Solar energy as source and make more
suitable for rural areas.
• More efficient than gasoline and diesel
engine.

3. WHAT IS STIRLING ENGINE
• Invented by Robert sterling (1816)
• Heat engine
• Converts heat energy to mechanical energy.
• Theoretical efficiency is nearly equal to their
maximum efficiency
• Developed in the automobile field

4. BASIC STIRLING ENGINE

5. STIRLING ENGINE WITH SOLAR
• Solar Heat energy source can be used
• Convert solar power into mechanical power
• Reduce cost and complexity
• Operate by letting heat flow of a hot source
• Efficiency is more than photo voltaic cell

6. SOLAR DISH COLLECTOR

7. WORKING PRINCIPLE
• If we have a fixed amount of gas in a fixed
volume of space and we raise the temperature
of that gas, the pressure will also increased
• If we have a fixed amount of gas and we
compress it (decrease the volume of its space)
the temperatures of the gas will be increased

8. SCOPE IN INDIAN MARKET
• On a medium-Large scale electricity
generation
• For industries
• On a small scale- home and buildings
• In agriculture
• Rural electrification

9. LARGE SCALE ELECTRICITY
GENERATION
• The cost of electricity generated is cheapest
when compared to other solar techniques.
• AC output
• No need of another setups
• There is no need for new transmission lines

10. FOR INDUSTRIES
• Reduced power cuts
• Each unit can generate from 10KW or even
lower up to 1MW
• Each individual unit is capable of producing
electricity
• An industrial area can be given its own power
generation instead of each company as no
larger scale, the system are cost effective

11. ON A SMALL SCALE
• Better than photo voltaic systems.
• Gated communities,municipalities etc
• 24 hour electricity guarantee is an attractive
feature to put up

12. AGRICULTURE
• Solar Stirling water pumps
• Solar Stirling pump is very compact hence can
be shared by various field

13. RURAL ELECTRIFICATION
• To reduce transmission losses
• Solar Stirling Generators can be set up in the
village premises itself.
• Single plant can be used for various
surrounding villages

14. PRIVATIZATION
• Small investment
• Manufacturing of Solar Stirling Generators is
possible with minimum hassle.
• Industries in private sector can manufacture
these and market not only within the nation,
but also abroad
• Private sectors find maximum scope in this
field.

15. COMPARISON WITH OTHER
TECHNOLOGIES

16. COMPARISON WITH OTHER
TECHNOLOGIES

17. HURDLES IN TODAY’S MARKET
• Well established PV market
• Few manufacturing challenges
• Known for being impractical
• Comparatively higher investment

18. FEATURE OF SOLAR STIRLING
ENGINE
• Environmental Friendly
• Quiet operation
• No need of new transmission lines
• Lesser payback period
• Comparatively longer life
• Cheap electricity generation

19. FEATURES OF SOLAR STIRLING
ENGINE
• Minimum Maintenance
• Digital display
• Easy to implement
• More utilization of sunlight due to the solar
tracker
• Hybridization

20. Applications
• Mechanical output and propulsion
• Electrical power generation
• Heating and cooling
• Other applications

21. ADVANTAGES
• The silence of operation
• The high efficiency
• The multitude of possible “hot sources”
• The ecological aptitude
• Reliability and easy maintenance
• An important lifetime
• The very diverse uses

22. DISADVANTAGES
• The variety of models
• The problems of sealing
• Heat transfers
• The lack of flexibility

23. CONCLUSION
• The new era in harvesting solar energy has
begun.
• It is just a matter of time before these engines
become a verypotential source of solar
electricity.
• Many countries have already invested in this
technology and are reaping the twin benefits
of nation development and environmental
fortification.
