solar panel amperage

is there a method of figuring what is the max amperage a solar panel can provide?

Here's one I found with a Google search. http://www.mtmscientific.com/solarpanel.html

Re: solar panel amperage

is it my ampermeter or i can't measure the amperage directly from the ampermeter? it shows only 0 whenever i use the 2 leads to check its amperage

Re: solar panel amperage

You should connect an ammeter in series with a load across the output of the solar panel. The meter by itself is like connecting the two leads of the panel to each other, a short circuit, and is probably not good for the panel.

you mean anode,amp-meter,resistor,cathode ?

Usually you have to put the red wire in a different hole in the meter. But I don't know what meter you have. If you have done this but measure no current then you have likely blown the fuse in the meter, or it was previously blown somehow.

Yes. And also you need another meter measuring the voltage across the resistor. This is to find the point of maximum power. However, you did not ask to do that so you might not care, I don't know. And make sure these resistors have enough wattage so they don't burn up if the panel is large. I don't know what panel you are using.
