If you already have a solar light, remember that it needs direct sunlight.Solar outdoor lighting is sensitive to the weather.If you want it to last, you should know some precautions and it is important to ensure proper care in order to keep it alive.If you want to know if solar outdoor lighting can still work at cold temperatures, the good news is, yes ---They are still working under these conditions (depending on the manufacturer and brand) and for owners living in cold northern weather you can expect your solar outdoor lighting to work as usual.There are some solar brands that are climate and waterproof, so please check with your supplier.Also, please note that the sunlight available in winter is reduced and may not be fully effective, so it is natural that your exposure time or the running time of solar outdoor lighting can also be minimized.To ensure its maximum functionality, keep in mind that solar panels are charged in direct sunlight.As a result, almost anything that blocks the surrounding lighting can adversely affect it, especially if it blocks the sun, which is the main light source for solar outdoor lighting panels.Although in most cases the light output may work, the available sunlight collected will still affect the intensity of solar outdoor lighting.In fact, while solar energy without sufficient sunlight may last for several hours at night, for your solar outdoor lighting, if you let it receive direct sunlight every day during the day, you still highly recommend it to play at its best to guarantee its maximum efficiency throughout the night.Regarding the photo sensor, they do have an on/off switch and will turn on automatically at night.This is how it works: when placed in the "on" position, the photocell device or sensor will be activated, the night light will be activated automatically, and it will be turned off automatically at dawn.Then, if the solar outdoor lighting is in "off" mode, the battery will still continue charging during the day.However, the photocell sensor will not be triggered, so the "dusk to dawn" process will not be started and the lights will be notified.If you think solar outdoor lighting is hard to maintain, think about it.The advantage of solar lighting is that you don't have to find an electrician to install complex wires for your lights.To meet your installation needs, you can use it simply by supporting the ground pile lights on the ground.You have to install your solar lights in street lights, trees, or other places where the lighting will not be hidden, which will activate the sensor, assuming it is the day, it is actually the evening.If so, your solar outdoor lighting will not turn on when the sensor light is activated by darkness
