How do you get energy from there? How do you deal with waste heat of satellite which is being heated up by sun from one side and heated up by your mode of energy transfer from the other side?

Unless we have some magical solution which can convert waste heat into electricity and thus making such satellite working with 100% effectivity, then such satellite needs to transmit energy with very limited power otherwise it will fry itself up.

Why 100% now? None of those satellites are exploding right now from overheating. Just add a laser on each pointed at somewhere where the energy can be used, done.

None of those satellites are also trying to collect as much energy on one side and beam them on the other side. Notice how those satellite closer to the Sun are wrapped into reflective and isolating materials and only antenna, solar panels and sensors are sticking out.

Additionally high power laser has currently something around 80% of efficiency. So if you have 10kW of input from solar array on one side, then you are transmitting 8kW via laser and 2kW into satellite itself as a heat. And again, we are in vacuum of space, so good luck with radiating 2kW of power into vacuum.

The fact, that you can't get rid of waste heat would need whole satellite to work close to 100% effectivity, which we don't have technology today
