I want to develop micro solar rc car, but I'm confused about Volts and mA on the solar panel.The micro rc car recharge through the remote control and the remote control use 3V (Two AA batteries). So, what Solar panel volts and mA should I use? Thanks?
Assuming this is a small model you will need to get a motor that uses a minimum of current - Often called solar motors they used to be often used in portable walkman type tape players but are still available.

this is a 2 volt motor and uses 0.06 amp so is ideal for solar use.
