Any time you have a question on if you're using the right wire, this calculator will have the answer. Also, you need to provide the specs of the devices in use. If you want answers, don't make us chase down the specs.

Specifications
6 amps
60' round trip
36v
Yes, 10 gauge is OK for that distance. You want the voltage drop to be 3% or less. If you have more panels in series then it's even better. But too many panels in series will run up against the max PV input voltage of the solar charge controller. Never exceed that.

You say 100 watt panel which makes sense for a 10A SCC but then you say panels?
Assuming 1 100 watt 10 awg is good at 1.83% voltage drop.

Voltage Drop Calculator
This free voltage drop calculator estimates the voltage drop of an electrical circuit based on the wire size, distance, and anticipated load current.

Do you have one or two 100 watt panels?
Ok but then why did you not say something when the results were based on 2 panels in series?
You use Voc not Vmp to size the SCC for max volts input.
Sorry it took a while to get back to you, you are right I now see I think I just over looked it. I tell my kids all the time give me all the facts so I can make the right decision,
and look what I did.
Thanks for the info, I'm hooking up a 10 amp 12v pump motor for my wife to have drip irrigation for the garden. Do you think the 10 guage wire will work for hooking the SCC to the battery
It will only be about 1 foot
It will only be about 1 foot, I do have other guage wire if 10 will be to smallIt depends on the wire distance. Fact man, just the facts.
10 gauge is fine.
Thanks again for all your help you really seem pretty to know your stuff
I learned it all on the Internet.
Good to know, I know I will be picking your brain down the road.
Thanks Again

Wait until he sees my YouTube Certification document! I keep it right next to my participation trophy.
