I have not experienced this but if it was putting out 19VDC and higher at 5-6AMPS I don't think I would like to do that. It could be the battery will load it down somewhat...
If it is a 12VDC type solar panel no problem...
Having 19VDC or higher might start blowing incandescent bulbs and other low current 12VDC devices...
This if course is the reason you should be using a SOLAR CONTROLLER to regulate the DC output to the proper setting for your battery bank...
Most panels produce the higher DC VOLTAGES to allow the solar controllers to output a good steady selectable DC VOLTAGE OUTPUT that you need.
just my thoughts...
