Microwave power transmission on the lunar surface

Assuming a lunar settlement uses solar power for all their energy
needs, the biggest problem is how to store power during the 328 hour
lunar night. If the solar panel 'farm' supporting the settlement were
split into three farms, evenly spaced around the circumference of the
moon, total power production would be relatively constant. This would
require greater production of solar cells than a single farm would use
but would eliminate the need to store energy for 14 days. Since the
cost to build and send the solar cell manufacturing system to the Moon
would probably far outweigh the operating costs, I expect even doubling
the total number of solar cells would be cheaper than building and
shipping a separate energy storage system to the Moon.

Rather than running cable around the Moon, would it be possible to
design wave-guides to carry the power efficiently as microwaves over
the 1000s of km between solar farms? How many would be needed and how
large might they need to be?
