Hi @Lerla_8! Even after already setting up your Cam, the Solar Panel can be introduced afterwards and it should operate as intended. Please ensure the Spotlight Cam battery is fully charged, the Solar Panel is plugged in securely, and it is receiving several hours of direct sunlight. The best way to know if your Solar Panel is charging as intended is to monitor battery level over time.
Keep in mind that excessive motion events, lengthy live view times, poor wifi signal, or even cold weather can drain your battery quicker than the Solar Panel can charge depending on these factors. I hope this helps!
