Solar Panels and Arduino
Solar Panels and Arduino
(OP)
Hey everyone,
First off I would like to say that I am a computer scientist not an engineer so this question might seem I little foolish but I recently started programming an Arduino I wanted to use solar power to power it. I bought two .5W 6V solar panels from radioshack. However when I tired to power the arduino it would not turn on. I measured the voltage using a multimeter and got 4.33V, I connected them to a 10ohms resistor to measure current and got .83mA, but according to Ohm's law shouldn't I be getting about 433mA. What is wrong are the panels not working correctly or am I doing something wrong. The measurements were taken with the solar panels connected in parallel, but I have also tried with the panels connected in series and still nothing(very little current).
Thanks for the help

RE: Solar Panels and Arduino
> A 10 ohm resistor would pull 0.6A, which is way more than your panel's capacity
> Your solar panels are too wimpy; the Arduino, whichever one it is, since you haven't said, is allowed to draw up to 0.5A.
