Basically, you can tap on Sun Gun to make them temporarily blind zombies. But they can also run out of power if used too long, causing them to disable. To recharge them, you have to tap on them, which will spend 75 sun. After that, you will have to wait for 21 seconds till it is up and running.

Seems a bit too complicated for a weak plant that just blinds the zombies instead of damaging them.
