I am new to electronics and need help. I have a mini radio that uses 2 AAA batteries to power it. The batteries are labeled Ni-Cd AAA 200mah 1.2 volt. My goal is to find a mini solar panel or 2 or 3 that can power the radio without batteries, but also charge the batteries when necessary. My question, how do I calculate or determine what strength solar panels I need to power the radio without batteries? I appreciate any help.
