Hi All,
Going to learn and start the ardunio journey. Planning to initiate the solar car project.
Can you please guide and share reference of some project. It should be pretty simple nothing fancy but works ! 
Regards,
Hemant
That's a very open question. Some suggestions:
Start by drafting requirements of what the car needs to be able to do. How big should it be and how much weight must it be able to transport? Do you want to have it run on solar power only, or also on a battery? Should it charge the battery from the solar panels if it's not driving, or if it's driving and not using all the available solar power? Under what kind of conditions should the car operate; e.g. temperature range, rain, what kind of road surfaces etc.
The other step to take would be to search for existing projects along these lines and try to learn from those. You'll find that many people have worked on this, ranging from small toy cars with a small panel and a single motor up to full-fledged cars that will fit one or more people and will run for thousands of miles (search for 'solar challenge') - the latter are anything but "pretty simple" and involve teams of people working with often cutting edge technology.
So take the first steps, and then as you run into questions you can't answer yourself, ask them here.
Why have you chosen this particular project?
Most people start with trying to blink an LED
What about learning the basics on programming and electronics first?
Thanks @rsmls for sharing your thoughts.
Yes - small toy car with a small panel and a single motor up. Solar panel charge the small battery - which can be be used for run the car.
Good, that gives a starting point. The question is if this will involve any Arduino at all; sounds to me it doesn't really need to.
What you'll need to figure out is how to deal with the various energy scenarios and charging/discharging the battery. Especially when the car is driving and there is not quite enough power from the solar panel to propel the car, so you need to use the battery. This can get complicated if you want to use both the solar panel and 'assistance' from the battery to supplement what the panel lacks at that moment.
The easiest solution is to just run the car off the battery and charge the battery when the car is standing still. In fact, that's where I'd start. Complicate matters later.
