A little advice re Solar Panels connected to Trail Cameras

Here we have one small detail that I overlooked in installing a Solar Panel to my battery charger setup, plugged into my trail cameras.

This information may be quite minor, but it is not detailed anywhere. Maybe people already know this but..

This detail only became apparent, when the solar panel had been left in the sunshine for month or so. It was noted that a thin plastic film was peeling off and going brittle at the edges.

I should have known. But this shows me peeling off the film. You might know get a few more volts/current out of the panel.
