Things To Do When Your Solar Lights Won’t Work

The consumption of solar energy is getting popular by the day. Thanks to technology, we do not entirely need to rely on technology all the time and instead, get some effective solution from nature itself. There are many types of solar energy that we use in our day to day lives these days. Solar electricity, solar chargers, solar pool heaters etcetera. But among these, solar lights are actually more popular than the other ones. Because solar lights have made our lives much, much easier.

Because of for example solar motion sensor lights, the electricity bills have decreased in a life changing way. So much money is being saved and these lights are just as useful and efficient. So what do you do, when these lights decide to stop working without notice? It is rather a common problem. Sometimes situations like this may occur from time to time. But good news is that you do not necessarily have to be a victim here because this problem is easily solvable. If you know how to, that is. So, here in this article, we will go through a few small and easy steps or things that you could do, if your solar lights stop working.

1.Make a shield around the solar panel: If you cover the solar panel, it will work as a trick as it will confuse the lights thinking as if it is already dark. Solar lights save the energy they get from the sun all day long and usually do not work during the day time because the energy is utilized in the night and the energy is being stuffed in the batteries as well.. So if you cover the panel the solar lights might start working if there isn’t any other source of light is reaching to the panels.

2.Readjust the batteries: The batteries inside the solar lights are always rechargeable batteries and lasts up to two years and sometimes even more (rare cases). These batteries save up the energy during the day time as the lights are off during that time and during the nighttime the batteries are active. So, if the batteries for some reason run out of their charging capability may cause the lights to not work. So double checking that is a must. If they are functioning as they should be, this has less chances of happening.

3. Avoid the shadow: It is advised to always check if the panels are shaded, and if not always than frequent checking is crucial. Any shadow over the panel will resulting in causing less absorption of the sunlight by the panel which will gradually decrease the required energy or the kind of energy that the panel is supposed to absorb for the day. So if anything like this is taking place, remove the object which is causing the shadow immediately and reposition the panel if needed.

4.Know your angle: It is actually the most feature of the solar panel adjustment thus the proper functioning of your solar lights. Sometimes, the sun may act lazy. It could get covered in the clouds or it could be a rainy or foggy day and especially during the winter when the sun is hardly seen. So, in times like this, it is best if you could adjust your panels to a forty five degree because that would be the most productive angle and it would absorb more energy than it would have in other angles.

5.Is it facing the south: A solar panel will be at it’s most productive form if it is facing the west. Because if you think about it, it will get much clearer. The sun goes up in the east and sets down in the west. So if the panel is positioned in the south side, it will get a full coverage of sunlight from morning till the evening.

6.Problems cause by the water: Although, this problem is not that common. Usually solar lights with higher ratings and from well known brands almost never have these kinds of problems, but every now and then these scenarios do take a place on a random day. So, if this ever happens, firstly remove any kind of liquid material that is placed near the panel and then keep it under a hot temperature so that the wetness dries off.

Make sure that the batteries are not hampered and if so, change them if needed. After a day or two of charging the whole again, the solar lights should start back working. A proper functioned solar panel should come with supplies that would protect the panel from such incidents so it is advised to double check these things before buying.

7.Restart the machine: The classic. BUT, it works 90% of the time. If you’re solar lights are having problems that seem unusual or won’t work all of a sudden, simply switch off the machine and turn it back on, maybe reset it as well. Chances are it will go back to normal.

8.Dust proof your panel: It is actually an important one, like the shadow bit. So if your whereabouts are near the main road or the place it dusty just like that, it may hamper the performance of your panel leading the lights going and staying off. So it would definitely be a good idea to wipe of those dust from time to time and make sure that the device is clean and is in a proper state.

9.Never charge near glasses: One of the most interesting things about solar panels are that it does not function well when put near glasses even if they are double or even triple layered. If your panel is situated near a glass, that right there might be the problem for the solar lights not working as they should. So it is advised to change locations sooner than later.

10.The Lux sensor: The Lux sensor detects or calculates how dark exactly it has to be for the solar lights to get active. Also if there is any other source of light from which the panel is getting energy or light from might lead to the problem here because it may still think that there is light outside. So, the Lux sensor verifies about that and helps it to function accordingly.

So, basically these were ten basic and yet most helpful things you could try and fix if you ever face such problem. Solar lights not working actually pretty common sometimes, which is why there are so many suggestions regarding what you could do during that time. So when in need, do not panic and simply follow these guidelines and hopefully the problem will be solved.

  1. My solar light won’t come on after dark.However if I cover the solar panel the light will come on. I checked the battery and it is fully charged. What could be the problem?

  2. It makes sense that dust could hamper the performance of pannels. My dad called me because of his solar panels at his facility. Thanks to your article, I will call a cleaning company that specializes in solar panel cleaning.
