How far can you run a portable solar panel from the battery?

[Derral Fiske]

Have you seen those portable solar panels? So my question is, I'm going to make a longer wire for this. So I can set up the solar panel further away from camp. Most times when I set up camp, I'm seeking shaded area. But that doesn't work for collecting solar rays. So my awesome idea of the day is to extend this wire. But my question is, at what point does the distance start to mess with the current getting from the solar panel to the battery?

Thank you for your help

I wouldn't go much further than 15'.

Only 15'? why is that?

Yes, the current gets dropped with longer stretches.
