9. PHOTOVOLTAIC ENERGY

10. SOLAR CELLS A solar cell converts solar energy to electrical energy
Photons in sunlight provide the energy that moves electrons from one layer of a semi-conducting metallic wafer to another
The movement of the electrons creates a current.
silicon and gallium arsenide cell are used

13. BODY & CHASSIS

14. BODY & CHASSIS
The main goals in designing the body are to minimize the aerodynamic drag
Minimize weight, and maximize safety.

15. CHASSIS
TYPES :-
SPACE FRAME
SEMI-MONOCOQUE OR CARBON BEAM
MONOCOQUE

16. CHASSIS SYSTEM
A space frame uses a welded or bonded tube structure to support the loads and the body
The semi-monocoque or carbon beam chassis uses composite beams and bulkheads to support the loads and is integrated into a non-load bearing composite belly pan.
A monocoque chassis uses the body structure to support the loads.

17. MECHANICAL SYSTEM

18. MECHANICAL SYSTEM Designed to minimize friction and weight. INCLUDES:
Suspension:-
Independent spring Wishbone type
Axle
Tyre & Wheels

19. STEERING SYSTEM FUNCTION:-
To meet turning radius & handling requirements.
TYPES :-
Bar & linkage steering
STEERING SYSTEM
