Re: MultiMeter Question
- Shorting out a _small_ solar panel to determine the short circuit
current should not harm anything. A reading of "23" on the 500 mA
scale is 23mA assuming that you have a digital multimeter. A 500mA
scale is a little odd for a digital multimeter though.
23mA is about the right output for the application you have described.
o What is the area and open circuit voltage output of a single panel?
