How to create a robot with batteries charged by solar panels? I have a robot that normally runs off of approx 7v with nicad AAs, I have a solar panel (12v) that im hoping to integrate into the bot. I would like the batteries to be trickle charged by the panels during the robots normal operations, and then fully charged while the robot is in a lower power idling mode. Am I able to attach the panel through a regulator right to the batteries?
Hello.
Before getting to your question, please don’t ask new questions at the end of completely unrelated topics.
What is the capacity of the batteries and what is the output of the solar panel? In many cases, you might not ever be able to do more than a trickle charge, in which case connecting the panel through a diode to the batteries might be all you need to do. (Don’t do that with other battery chemistries!)
