On rails, you could carry 10 times as much weight. A barge on a canal, 50 times as much. Allowing for losses, that's about a 100-watt panel in strong sunlight. If there is any uphill, that's an entirely different matter. Here is an antique table with guidelines as to how much a man or a horse can draw in a cart at various speeds:=&f=false

A barge on a canal, 50 times as much.

If there is any uphill, that’s an entirely different matter.

I do know that a cyclist cruising along at a moderate speed (say, 10 miles an hour) is expending about 1/10 horsepower. That's 80 watts. So on flat ground, a 100-watt panel push them over the 10 miles in an hour. Such a panel, if square, would be 2 to 2.5 feet on a side, if made with typical contemporary materials. If the terrain is more than gently rolling hills, more power would be needed. I came accross a new, proven and tested home made wind power system and solar power system which eliminates our electricity bills. It was written by a Renewable energy enthusiasts Michael Harvey the diy called Earth4energy. You can get your copy to save energy and help environment while eliminating your power bills.
