True story: two football players who lived on my dorm floor were waiting for the elevator, on their way to a night math exam. One pulls a new calculator out to show his buddy: "It's solar. Now I don't have to worry about the battery going dead during a test."
His buddy puzzled on it for a minute then said "Yeah? But what if the lights go out?"

To be frank, if the lights go out, a regular calculator will also be useless, unless it s display is backlit.

Lots of old ones had LED displays, although you wouldn't be able to see the keys.
This was my previous calculator:
