question,, which is better when looking at solar panels.??

Higher voltage, ie.. 24 vs 12 or max amps they can produce. example: I am looking at a panel rated at 195 watt, 24vdc that produces 5.38 amps and another one that is 160 watts, 12vdc that produces...

Up to about 360 watts or 30 amps, 12 volts and a PWM controller is better. Those would be 12 V panels, and you be concerned about what the lsc or amperage during short circuit reading is, the higher the better. 18V under max load is good, 17.0V under max load would be better, the amperage rating would be higher. This is all for 12 Volt rated panels. I'd also insist on Poly crystalline panels, not mono panels.
