I'm installing a panel on my roof and wondering if 1-2 feet (maximum -- ideally it'll be more like 8 inches) of 16 gauge wire will mess things up.
The reason I'd use it is to get the wire through a small hole and through the roof. I've got a side-entry cable clam that can accept wire up to 7mm. I really want the wire to be as flat and low as possible. Finding UV-resistant wire (with my experience anyway) has been tough, especially 2 tray wire.
To stay below the 7mm so I can get it through the hole, 16 gauge was the biggest wire available. The rest of the run is:
The panel is a 90 watt Global Solar panel that might put out 5-6 amps -- under ideal conditions.
I've fiddled with DC/Wiring calculators, but I don't know what happens if you insert a short section of small wire in the middle.
So what would you say -- will I regret using that short section of small wire?
Thank you.

- 4 feet of 10 gauge from the panel (and will splice it to this 16 gauge section as close to the hole as possible)
- Then inside the camper they pre-wired with 12 gauge for the most part (that's maybe 20 feet of wire?)
- Then 3 feet of 10 gauge to the charge controller
