As I understand it, solar panels have a maximum theoretical efficiency that's much lower than that. 33% for a conventional design with others apparently going a bit higher, but I don't think you can ever get anywhere close to 95%. There's also the question of transporting the electricity efficiently. Still an interesting hypothetical question though. Maybe you could achieve the same effect more easily with mirrors.
