It is possible that she read the wrong number.  It would seem that 
the voltage from the array would be higher than the battery voltage 
as it was full daylight (despite shade),.but It is possible that the 
array voltage could have been lower.

This is what I'm beginning to think.  The actual charge rates I've 
seen are not that high, but the batteries are likely tired.
