   The solar module (panel) with the lowest voltage I know of is rated at about a half amp at 15.6 volts. This module would charge any rechargeable battery of 12 volts or less. It would require resistors to limit the current, and would overcharge the battery without a sophisticated charge-limiting circuit.
   Look on the web for the Siemens ST-5
