I can scarcely imagine what sort of marketing "genius" managed to produce the weird copy here. That solar panel looks to be about ten feet by thirty feet, so you can just about bet your sweet bippy that some assembly is required. Not that the assembly would be a problem, but why say such an irrelevant thing? Taking a guess that a favorable insolation value is about 7 watts/square foot, this panel might produce around 2100 watts. If you want to charge a 250 amp-hour 48-volt battery pack (to pick some rough numbers) from half to full charge takes 6000 watt-hours (125 x 48). Does anyone want to sit around for almost 3 hours to top off their batteries? And 4 customers during daylight hours? Welcome to GreenWorld, where arithmetic don't matter.

(No, I am not really so cynical about this, because there are indeed many good ideas; but there is so much DOA nonsense out there. Doesn't anybody check this stuff? And who rakes off the taxpayer-financed subsidies?)
