Because the Moon always points it face at the Earth, it rotates on its axis only once a month. For this reason, at the equators, the Moon's day lasts for two weeks and its night also lasts for two weeks. If an initial base were to located near the equator it would have to have a power system such as nuclear power in order to provide the base with enough power to survive the two-week night.

Fortunately, the Moon's is barely tilted compared to its orbit around the Moon. As a result, there are locations near the north and south poles where sunlight shines for greater than 90% of the time. Additionally, these locations tend to be close to certain craters where the sunlight never hits their floor. In 2009, NASA's LCROSS mission conclusively demonstrated the presence of water ice and organic chemicals in one of these permanently-shadowed craters in useful concentrations.

So, how could the power from solar panels at the Peaks of Persistent Illumination (PPIs) get down to ice-harvesting telerobots on the nearby floors of the permanently-shadowed craters? There are a number of possible solutions which people in the field have discussed. The lander could drape a wire from the crater rim to the floor while it hops between those two points. Likewise, a small rocket could lay out the wire in a one-time shot. There are plausible ways of beaming power using either microwaves or lasers. The advantage of this approach is the savings of the mass of the wire. An interesting solution which could allow for a wide separation of ice and power would be to run the lander's residual propellant through a fuel cell to produce electrical power in order to provide the telerobots their power and body heat. Once full with water, the lander could hop to the power

The lunar poles requires only solar power.
Nuclear power is not necessary for the forseeable future.
