I still think people are not reading the San Diego document. We posited a reasonable 60w DC for the C band amplifiers with an aggregate 20 -ish w output, split amongst the elements or something reasonable like this. That is 2-ish watts per antenna DC. Again, in the San Diego document, we guessed at the overall power budget and as before, we guessed at a number that is identical to the one you have been worried about our needing and further, we acknowledge in that document that is costs $1200/w. We are completely aware that the solar generator is MOST of the cost of the satellite and by a lot.
READ THE DOCUMENT.

Bob, I am very worried about this huge requirement for power. I am concerned that we are making a satellite that that AMSAT will not be able to afford.
We also need to resolve the question of how much power needs to be supplied during the worst case eclipse scenario. This has a major impact on the amount of energy storage is required.
Another question is whether we are going to stay with the requirement of being sun angle neutral. These are all drivers for the size of the spacecraft and the structure.
