Their ad sounds a bit "snake oil" to me. They claim their 68W panel will recharge 2 6 volt batteries in 7 to 10 hours. How is a 68W panel going to recharge a 220Ah battery pack in 10 hours? That's not even enough to recharge a single 100Ah 12v battery that has been discharged to 50%.
They leave out enough details to cover themselves. For example, they don't say "recharge," they say, "charge." And they don't specify which panel. They could be talking about their 18' long, 144W unit. And of course they fail to mention any details about how far the batteries are drawn down.
However, your point is still well taken. It's pretty misleading. But I think that's the retailer. I wouldn't blame Uni-solar for that.
I almost bought one of the longer units for a killer price! But alas... it was just too long for my rooftop. Wattage per surface area is definitely not their strong suit.
