Do cracked solar panels work?

Cracked panels work if we define a working panel as one that produces a current. At least most of the time, cracks don’t damage the solar cells themselves. These cells are among a solar panel array’s most critical components. Even if a solar cell has been damaged, that doesn’t compromise the entire panel.
