How many hours can solar LED street light work in a night?
Many customers want to know how many hours does their solar LED street light can work a night, this would be decided by the power generation of solar panel, usually, most of solar LED street lights which are used for countryside can work around 6 hours a night, it can work around 8 hours for urban communities, it should work whole of night for factory. Currently, solar LED street light is widely used for countryside.
Taking the solar LED street light which is applied for countryside as example, it would bright 6h~8h each night, this lighting time is decided by customers when they purchased, manufacturers can allocate the power of solar panel, battery capacity and the size of solar panel according to customers’ requirement, so that it can meet night lighting and backup for rainy or cloudy days.
For example, if LED lamp consumes 0.1KWH to light 6 hours in a night, then the solar panel need generate electric power at least 0.1KWH each day, the surplus power can be stored into battery to backup for rainy or cloudy days.
Some customers just need low prices when they purchase solar LED street light, then they need reduce the lighting time, this allocation also can be made according to customers’ project requirement.
Usually, there are many normal allocations as below:
The lighting source of 5m height solar LED street light: 9W~18W;
The lighting source of 6m height solar LED street light: 18W~30W;
The lighting source of 7m height solar LED street light: 30W~42W;
The lighting source of 8m height solar LED street light: 42W~60W;
The lighting source of 9m height solar LED street light: 60W~80W;
The lighting source of 10m height solar LED street light: 80W~100W;
