Reply to comment by IWasGregInTokyo in NASA astronauts unfurl 4th solar array outside space station by IslandChillin

I think I remember them being marginally more efficient, but all solar arrays start losing efficiency at first light, especially in the harsher environment of space. They’ll be way more powerful just by being newer.

See my other comment in this chain. New space solar is 30% efficient, compared to 12% for the old Station arrays when new. That's why the new roll out arrays can be so much smaller.
