The voltage and amperage depend upon battery charging status, charge controller, sunlight, tilt of panels, etc.
I have seen 14.2-14.4 volts with up to 16 amps at a time.
I have 1x100 watt panel and 2x120 watt panels.
It was July in Southern Idaho.
Batteries were at 60-75% at that time.
I do not tilt my panels.
All flexible and glued to the roof.
My experience has been 5 amps per 100 watts under ideal circumstances is realistic for those type of panels.
