Why some solar light turn off early and other can work longer time while the same solar light(without quality problem) install in same place.

1 .Solar panel in different direction can get different battery charged Performance.The shelter will also lead to reduce the efficiency .This will lead the battery charged and lighting time different.

2. The solar light with motion sensor, If one light with many people pass by and another light with less people pass by, then one(with many people pass by) of them turn off soon. Because the motion sensor for high light need more power.
