Question:
Is this available in 10awg? If not how long of an extension cable can I use for portable 220w panel? Also, what guage extension do you recommend? If 10 extension for longer distance and this is 12… does that work or wasting$ on 10 awg extension?

Hey Todd, unfortunately the Go Power RV SAE for Portable Solar Panels # GP49QR is not available in 10 AWG. For an extension you can use the 12 Gauge 2 Conductor Jacketed (Brake) Wire Per Foot # 12-2-1 since it's just bonded 12 AWG wire used on the pigtail.
I'd recommend using the Deka Heat Shrink Butt Connector # DW05745-10 to make your wire connections. I used to use these for everything when I was building performance boats and they always held up great, so I have no doubts that they'll work for you!
The wire is sold by the foot by the way, so if you want a 4 foot section you'd have to buy 4 of # 12-2-1.
As far as size goes for a 220-watt solar panel, 12 AWG wire can safely carry the current for runs up to about 100 feet, so if you're making a run longer than that you'd need to beef the wire up.
If you have any other questions, please feel free to drop a comment and let me know!
