Just a small correction here; the flares are not from the solar panels,
rather the Main Mission Antennas. I imagine the reflection of heat in this 
case is to prevent heat damage and deterioration, and possible to prevent 
warping or stresses that would shorten the life...I can't imagine they have 
to be perfectly flat for aiming purposes.
