Hi rjsurfer,
If you look at the manufacturer's data sheet you will see a term called "temperature coefficient Pmax". For example the temperature coefficient of a Suntech 190 W (monocrystalline) solar panel is –0.48%. What this means is that for each degree over 25?C … the maximum power of the panel is reduced by 0.48%. It is not "adjustable" so far as I am aware, but rather a "fact of life".
Voltage goes down as temperature increases.
