those round cell ones look like OEM seimens panels
36 cells approx 18vmax 15.5v nominal
comparing them to size of the A/C they are small by todays standards, but normal when MFG, i would guessitmate them at abut 30w each
the 4th panel is more recent looks to be poly crystal
is as wide as the a/c unit and much longer could be 80~120w panel
i would guess about 200w total, would be a close guess
