All Electronics Corp is a supplier of surplus electronic and mechanical parts.
You can wire individual Solar cells into nearly any voltage you need. A single solar cell typically produces about 1/2 volt. The prefab panels have just connected a number of cells in series to obtain the higher voltages.

There are many distributor sites on the Internet. If you have a part number, that’s a good start. Here’s one but there are thousands.

Most Radio Shack stores have drawers in an inconspicuous place in the store where they keep such components. You will probably know more than most of the store clerks about these parts.
