Battery and Solar Panel

I bought a Stick Up Cam with a Solar Panel a month ago, I have already had to recharge the battery 2 days in a row because the Camera wont work. Right now, the battery is at 0% and as soon as the sun goes down, the camera turns off and wont record or send me notifications. I want to know why the battery is draining so fast and if the solar panel is not working correctly? The point for the solar panel is to keep the camera charged at all times isn't it? Please someone help, thank you!
