The guys name was Louis Palmer, who drove a vehicle called the Solartaxi around the world (32,000 miles) in about a year and a half.
The car and trailer together only came in at 1650lbs, boasted a top speed of 55mph and claimed to get 133wh/mile. The solar panels on the trailer came in at about 6 square meters. It used a liquid salt Zebra battery, and claimed 250 mile range, but it also mentions 14kwh when discussing battery costs, so I might be missing something. The whole thing feels a little light on facts, which I am guessing is because it does not quite deliver all it promises. Or because the whole thing was built by a bunch of engineering students, and the guy who drove it did not really fully understand how it all worked.
So, yeah, that array, if it was really efficient would be nearing 1.5kw. My array happens to be that size, and on a sunny summer day at 45degrees north lat. I can pull in 6kwh in a day. If that was feeding a car that used 133wh/m, it would equate to a 45 mile range. Some form of battery would be a must, as you would burn through that 45 miles in a couple hours, while needing a good 7 or 8 hours of sun to accumulate that much energy.
Anyway, it sounds like the OP wants someone else to do all the work for him, so maybe try contacting some local universities? I will say I am fairly impressed with the stats that this thing manages to put out. Granted, a relatively fit person could easily outdistance it on a bicycle, and since it is a fair weather proposition anyway, it would be a lovely bike trip.
