The maximum accumulated solar radiation varies greatly by latitude when taken over the whole astronomical summer. At the 80S the max is 2870 MJ/m2, at 60S it is 4200MJ/m2 and at 40S 5300MJ/m2. That's why on the map with raw energy values the Antarctic appears significantly whiter than the north, even when regions are mostly icefree. Instead of energy values the chart on the left shows the percentage of locally avaliable solar radiation.
