Regarding the (maybe completely absurd) possibility of powering a satellite via a ground-based laser, and perhaps (theoretically) also using that same laser to destroy any incoming projectiles or debris that might threaten the satellite, this might be most useful for a satellite that a) has little access to solar power, and/or b) is designed to be as small as possible in size (perhaps for reasons of defence?), lacking room for big solar panels or fuel tanks or batteries.. With that sci-fi thought in mind, which low-earth-orbits spend the least amount of time in the sunlight?
