Im Holding Anyone Harmless in case their Answer causes a catastrophe (Im sure its somewhere in the Site TOS too) so here it goes:
Ive been given hundreds of feet of 4x18AWG Speaker Wire. Normally they like to run Regular 12AWG for 150W Solar Panels. I'd like to use the 18AWG since I'll save and cannot really afford to buy more 12AWG wire going about 40 feet. Each 4x12VDC/150W wire for Positive, and ONE separate 12AWG shared Ground Wire = 600Watts.
What are your Credentials/Solar-Experience and in your opinion can I get by with this Gauge/Plan for at least a little while?
