Regarding StickUp Cam and Solar charger

I purchased a StickUp Cam and solar panel for my outside shed. The cam recognizes the Solar panel as a power source. However, I have to charge the battery every two days - even while connected to solar panel. It is clear the panel isn’t working and keeping the battery charged. This is a low traffic area so alerts aren’t hourly or daily. What do I need to do to change this to a spotlight cam? It’s clear the stickup cam isn’t ready for outside use, even with a solar panel attached constantly.
