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...

You really need a more expensive MPPT controller to get the most out of the 24v panels.

As you get into the 250 to 500+ watt range the larger panels make more sense IMO.

With MPPT controller you are just looking at physical size and watts. With a PWM controller and 12v panels it is the Isc rating that matters.

Need to post what you want to accomplish with solar.
