Hi all -
I've been theorizing about powering a micro-rc (zz in my case) entirely off a solar cell mounted on top of the car. I'm trying to figure out what the minimum voltage/amperage would be to run the car. It sounds like a standard battery provides 1.2V at 100uA, and that voltage effects motor power and amperage effects run time. It kinda makes sense since total wattage in battery would be V*A. I've found several sites on the web that have indoor and outdoor cells that might do the job. But do I have to reach the volts more importantly that the amps, since it's a continuous powers source? ie would 1.5V at 30uA do it? As part of the solution a capacitor could be used to offset high power usages such as accelerating. I've found a couple cadidate cells here:
