I'm not a solar power person (although I have 500Wp on my roof) so I 
am confused.  Is it the extra voltage from cold weather giving you 
your extra current?

I would doubt if 1% volt drop is a cost-effective target for volt 
drop in many cases.  The actual loss of current into the battery will 
be much less than 1%.  The overall % energy loss will be considerably 
less still, considering how often you will be getting below peak 
power.
