> The area with the highest incidence of sunlight was 89% at the north pole, followed by 86% at the south pole, equating to 324 and 314 days of sunlight a year, respectively. There were also many areas around crater rims where the yearly percentage of sunlight was at least 80%. The existence of polar areas believed to be in permanent shadow was confirmed by the survey.

They'll be fine with some batteries, and the poles are already prime spots due to permanently shadowed craters holding ice.
