Which regions receive the least solar radiation throughout the year?

The regions that receive the least solar radiation over the year are the high-latitude polar zones — especially the interior of Antarctica and, to a lesser extent, the Arctic. Key reasons and details:

- Polar regions (above ~66.5° latitude): very low sun angles for much of the year, very long winter nights (polar night), and a long atmospheric path that scatters and absorbs more sunlight. These combine to produce the lowest annual totals of incoming solar energy.
- Antarctic interior / South Pole: the single lowest annual-insolation area on Earth because of extreme latitude, high surface albedo from snow/ice, and long, dark winters.
- Arctic sea-ice and surrounding high-latitude land: also low annual insolation, though somewhat higher than the Antarctic interior because of differences in land/ocean distribution and seasonal day length.
- Persistent-cloud regions at mid/high latitudes: places such as parts of the North Pacific, North Atlantic (northwest Europe), and some maritime subpolar zones receive reduced solar radiation relative to sunnier latitudes because of frequent cloud cover — but their annual totals are still typically higher than the polar interiors.

If you want, I can show maps or numbers (annual mean insolation) for specific locations or latitude bands.
