That sure is an ambitious project... it is much more difficult than a satellite in earth orbit.
The issue you are facing is that a spot on the moon will receive sunlight for 14.5 days and then will
be in darkness for 14.5 days. During the sunlit period it will bake in the sunlight to temperatures
of 120C, during the dark period it will cool down to -150C and below.
It will be required to catch and store energy during the sunlit days and have enough of it in
batteries to heat the spacecraft to temperatures where it will not be killed during the nights.
Professionals can fall back to nuclear energy, but that is unpractical for amateurs.
It will not be easy... Good luck!
