Solar PV Cable 8 AWG (8.36mm^2)
[345]

I have a 280W monocrystaline panel and a 500W inverter. I started with 12 AWG wire and was only pulling around 180W. After switching to this 8 AWG wire I'm now seeing the full 280W that the panel will produce. I highly recommend this wire in order to receive the maximum output from your panel(s)!!!
