What operational advantage do Peaks of Eternal Light (PELs) offer landers and habitats?

Providing constant solar energy without reliance on the two-week lunar night

Peaks of Eternal Light (PELs) are elevated areas, often the rims of craters near the South Pole, that stick out above the permanent shadow line and receive almost continuous illumination from the Sun, which hovers low above the horizon. This constant energy supply is vital for sustaining a long-term lunar presence. Without the lengthy, two-week-long lunar night experienced elsewhere on the Moon, habitats and ISRU operations situated on these sun-drenched ridges can draw uninterrupted power from solar arrays. This negates the necessity of carrying massive, heavy battery storage systems or relying on complex nuclear generators, making the PELs crucial components in the logistical blueprint for self-sufficiency.
