Building a solar powered 3 wheel vehicle

Hi
I want build a solar powered 3 wheel vehicle. But I do not know how much back up the vehicle named as auto rickshaw will get from the solar panel? Which type of solar panel should be used to back up the rickshaw for about 8 hours. My country is Bangladesh.
Thanks again.

Are you planning to use the panel to charge a battery, or to power a motor?
What are the battery and motor specs?
I think you'll find you need a very large panel, or panel array, if this is a full-size rickshaw rather than a model.

You will find the panels will need to be bigger than your rickshaw can hold.

Nah, you just have to think positive, anything is possible.

Funnily enough, I'm sat with four solar panels immediately behind me

They are 125cm x 81cm each, and I 'think' they are rated at 150W (they are secondhand, so no specs).

Bear in mind these are 150W absolute maximum, and I doubt the 600W of panels would be much good for powering a rickshaw?.

Incidentally, the MPPT controllers for them (we have six?) use a PIC16F877
