solar pre-wired questions

Sure Mono panels are more efficient (by about 3%), but in practice, when comparing panels of ‘equivalent wattage’ the actual power difference is equivalent, except that the poly panel will have a slightly larger footprint, while at a slightly lower cost (per watt), and as far as I can tell, I’ve seen no substantial difference in warranty…At least that’s been my perspective, and my personal priority would be (1) shape/size (efficiency may be a factor…), while (2) closely matching voltages with other panel voltages - cost advantage would be of lesser concern…JMO - leaving room for others who might view this situation somewhat differently…
