Place on Moon that always lit? Is there a place on Moon (sure it's near north or south pole) that is always lit by sun? It's to install solar panels if I will choose to make rancho there :)

What diameter of Moon Polar circle?
How high the hill or mast on the pole should be to be always lit?

I used some online calculators and found next:


  Axial tilt to ecliptic is 1.5424°, Lunar Radius 1738km
  
  Polar circle is 46.8km
  
  Spherical cap height 0.15km


Are my calculations correct? It shows that it should be near 150 meters high. Is any high enough hill exists on a poles? 

P.S. Where I can check good 3d model of Moon with elevation (sure there is no sea level but ideal sphere)?

Thanks
This kind of location is called a peak of eternal light.

Apparently there is no certain identification of such a peak on the Moon, but there are definitely places that get more than 86% sunlight during the lunar year (ignoring eclipses). Kaguya did not find any permanent peaks, but there is apeak near Peary at the North Pole that gets 89%, and several places near the South Pole that have multi-month illumination. 

Calculating the requirements for such a peak is complicated since the moon is definitely not spherical on the hundreds of meter scale; at the very least one needs an ellipsoid model. The south pole situation is complicated because there is a large basin around the actual pole.
