Recent terminology change

When did they start calling deployed photoelectric power sources on spacecraft 'solar wings' rather than 'solar panels'?

I suppose they are very occasionally actually used as wings, but the only example I can think of it aerobraking into orbit around Mars.

If you're going to go for biology metaphors, "solar leaves" would seem more appropriate.
