Hole in solar panel

When I arrived at the cabin, I found that one of my panels has a small hole through it, much like a rock hole in a car windshield. The panel is still generating some power. If I just seal over the whole to prevent water leaking under the glass, is there any downside?

    Well, tape sealed over the hole will help some, didn't the glass completly shatter, or is this a homemade panel ?

    When vater vapor gets in and condenses (like in a wristwatch), you cannot get it out, and eventually the cells metal plateing corrodes and the panel is dead.

    You can buy a kit at most auto parts stores that's made to repair "bulls eyes" in auto windshields. It's made by Permatex and costs about $6 (last time I got one).

    There's a syringe that adheres to the windshield and draws a vacuum, then fills the bullseye with a resin that hardens by exposure to ultraviolet light (sunshine).

    Would this fix your hole?

    if the hole is too large that windshield repair kit won't work too well. look over this item from another thread.
