5.2 MOTOR CONTROLLER DESIGN
In the actual design of our project, there is controller to control the speed of the motor. In our
implemented design we use a rheostat for control the speed of the motor manually but in future
we will control the speed of motor using microcontroller.
5.3 IMPLEMENTING FLEXIBLE SOLAR PANEL
In future we are planning to use flexible solar panel in our solar powered clean car. Flexible solar
cells are manufactured by depositing photovoltaic material on flexible substrates, such as
ordinary paper, using chemical vapor deposition technology. By using flexible solar panel we
can use the total surface area of the car and we get more energy from the solar panel to drive the
car. In conventional solar panels, the supporting structures of the panel like glass, brackets metal
etc. are mostly twice as costly as the photovoltaic materials manufactured on them. As paper
costs approximately a thousandth of glass, solar cells using printing processes can be much
cheaper than conventional solar panels. Such solar panels can produce a voltage more than
50volts. The current efficiency of the solar panel is near 1% and it will improve in the near
future. Addition of Possible Large loads
5.4 INCREASING VEHICLE SIZE
The original design of our vehicle is for two passengers only. In future we will try to make it
large because if the vehicle is large then more passengers it can carry and if the size of vehicle is
large then there is a large area to implement the solar pane.
