Solar lights are perfect for illuminating your outside space as well as helping save on your electricity bills. But when your solar lights not working, it can quickly dampen the mood. Before you give up on those cheerful beacons of light, there are a few simple troubleshooting steps you can take.Here are ten main potential issues why your solar lights are not working, and how to fix them:
Why do solar lights stop working?
Solar lights not working can be a frustrating experience, especially when you’re not sure why they’ve suddenly gone dark. There are several reasons why your solar stake lights, hanging solar lamps, or even those brand new solar lights with on/off switches might have stopped working. It could be a simple fix like a dirty solar panel or a dead battery, or it might require a bit more troubleshooting to identify the culprit. Whatever the case, don’t give up on your solar lights just yet.
10 Things to Check Before You Give Up
Check the Power Switch
The first thing to check when troubleshooting your solar lights not working is the power switch. Many solar light models, whether they’re a Bell + Howell outdoor spotlight, a Magnavox stake light, or a simple hanging solar lamp from the dollar store, have an on/off switch. This is especially true for brand new solar lights that might not be activated out of the box.
The switch can usually be found on the underside or back of the solar panel, sometimes tucked behind a small cover. It might be a simple slide switch or a push button. If the switch is in the “off” position, the light won’t turn on even if the solar bulbs are working perfectly and the panel is receiving enough sunlight. So, if you’re staring at a seemingly lifeless solar lantern or a string of unlit mini LED solar lights, this simple step could save you a lot of unnecessary solar light repair work.
You see, the light does not come on during the day just because it does not mean that the light is defective. The solar lights are designed to turn on automatically when it gets dark, so don’t panic if they seem unresponsive in the daylight. Simply flip that switch to the “on” position, and you’ll be well on your way to restoring the glow to your garden or pation.
Inspect the Solar Panel
take a close look at the solar panel. This is the heart of your solar light system, as it’s responsible for converting sunlight into the energy that powers your lights. A dirty solar panel can’t absorb sunlight effectively, which means your lights won’t charge properly.
Dust, dirt, pollen, leaves, or even bird droppings can accumulate on the panel, especially if your solar lights are in a garden or another exposed area. A quick wipe-down with a damp cloth can make a big difference. For stubborn grime, try using a mild soapy solution.
The position of your solar panel is equally important. It needs to be facing the sun for the majority of the day to absorb enough energy. Ideally, it should be facing south (in the northern hemisphere) and angled so that it receives direct sunlight for as many hours as possible. If your solar panel is shaded by trees, buildings, or other objects, or if it’s facing the wrong direction, your solar lights may not charge fully, resulting in dim or non-functioning lights after dark.
Examine the Batteries
If your solar panel is clean and well-positioned, but your solar lights are still not working, it’s time to examine the batteries. Even with a fully charged panel, your lights won’t function if the batteries aren’t up to par.
First, check for any signs of corrosion or leakage. If you notice a white, powdery substance or any liquid around the battery, it’s time for replacement solar bulbs or batteries. Corroded batteries can damage the light’s internal components and should be disposed of properly.
Even if there are no visible signs of damage, old rechargeable batteries can lose their ability to hold a charge over time. If your solar lights have been working for a year or two, it might be time to consider replacement solar panels for outdoor lights or replacement solar light bulbs for outside.
Test the Light Sensor
If your brand-new solar lights won’t turn on, check to see if there’s a small pull tab sticking out of the battery compartment. This tab prevents the battery from charging during shipping and needs to be removed before the light can start working. So, if you’re wondering, “Why are my brand-new solar lights not working?” This might be the answer!
If your solar panel and batteries seem to be in good working order, it’s time to test the light sensor. This component tells the light when it’s dark enough to turn on. A faulty sensor can lead to solar light not working even when the other parts are functioning correctly.
To test the sensor, simply cover the solar panel with your hand during the day. The sudden darkness should trigger the light to turn on. If it doesn’t, it could be the sensor that needs to be replaced since the board might only be triggering the sensor instead..
If the sensor is faulty, you might need to replace the entire light fixture, as individual sensors are often not sold separately. However, before you do that, it’s worth double-checking all the other components, as a loose wire or a depleted battery can sometimes mimic a sensor problem.
Check for Nearby Light Sources
Check for Nearby Light Sources. If your solar light sensor is working correctly, the presence of nearby light sources can interfere with its operation. Streetlights, porch lights, or even the security light from your neighbor’s house can trick the sensor into thinking it’s still daytime, causing your outdoor solar lights not to work as expected.
If your solar lights are installed near any of these light sources, they might not turn on at all or might turn off prematurely as dawn approaches. To troubleshoot this, try moving your solar lights to a different location, away from other light sources. If this solves the problem, then you know that light interference was the culprit.
Inspect for Water Damage
Solar lights are designed for outdoor use, but even the most durable models can fall victim to water damage. In the case of moisture penetrating through the casing, the parts inside can be eventually corroded, and the battery contacts, wires, and the solar panel are part of it. If you’ve experienced a particularly heavy rain or snowstorm, it’s worth checking your solar lights for water damage.
Look for any signs of condensation or water droplets inside the light casing. If you see any, try disassembling the light (if possible) and drying out the components thoroughly. Use a dry cloth or paper towel to wipe away any moisture, and if possible, leave the light disassembled in a dry, sunny location for a few hours. Sometimes, simply drying out the light can restore its functionality.
However, if the water damage is extensive or if you’re uncomfortable disassembling the light, it might be best to replace it altogether. Water damage can be tricky to fix, and attempting a DIY repair might void the warranty or even create a safety hazard.
Look for Loose Wires
Sometimes, the reason behind a malfunctioning solar light is a simple as a loose wire. If your solar light flickers intermittently or refuses to turn on altogether, a loose connection between the wires and the internal components could be the culprit.
This may be because it has worn out, got damaged in an accident, or was produced with a manufacturing flaw.
To check for loose wires, carefully open the light fixture (if possible) and gently wiggle the wires where they connect to the battery, solar panel, and LED bulb. If you notice any loose connections, try tightening them by gently twisting the wire connector or securing them with electrical tape. However, if you’re uncomfortable working with electrical components, it’s best to seek professional solar light repair or solar lamp repair services.
Remember, safety always comes first. Disconnect the solar light from the power source (i.e., the sun) before attempting any repairs, and wear gloves to protect your hands from sharp edges or hot components.
Give it Time to Charge
If you’ve gone through all the previous steps and your solar lights are still not cooperating, don’t lose hope just yet. Sometimes, the solution is as simple as patience.
If you’ve just installed new solar lights or recently replaced the batteries, it may take a full day or two of direct sunlight for them to charge completely. Even if your solar panel is working perfectly, the batteries need time to store enough energy to power the lights through the night. This is especially true for larger lights or those with multiple LEDs.
To get solar lights to work after replacing batteries, ensure they’re installed correctly and the polarity (+ and -) is aligned. Then, turn the on/off switch to the “on” position (if applicable) and place the lights in a sunny spot. Leave them undisturbed for 24-48 hours to allow for a full charge. If the lights still don’t turn on after this period, you might need to revisit the previous troubleshooting steps.
Consider the Weather
solar lights have been working fine but suddenly seem to be dimming faster or not turning on at all, don’t forget to consider the weather. Cloudy days or shorter winter days can significantly impact how much sunlight your solar panels receive, and therefore, how much they can charge.
While some high-quality solar lights can still gather some energy from indirect sunlight, they won’t charge as efficiently as they would on a bright, sunny day. This can lead to shorter illumination times or even cause the lights to remain off completely if the battery hasn’t stored enough energy.
So, if your solar lights are acting up during a period of cloudy weather or in the winter months, it might not be a malfunction. They might simply need more time to charge. If you’re wondering “can I leave my solar lights out in winter?”, the answer is yes, but be prepared for them to have reduced performance due to the limited sunlight. In such cases, relocating your solar lights to a sunnier spot, if possible, or investing in solar lights with larger solar panels or batteries can help mitigate the impact of weather-related charging issues.
Check for a Reset Button
If you’ve exhausted all other troubleshooting options and your solar lights are still not working, there’s one more thing to check before throwing in the towel: a reset button. Some solar light models, particularly the more advanced ones, come with a reset button that can sometimes resolve minor glitches or errors.
If your light has a reset button, it’s usually located on the underside or back of the solar panel, often near the on/off switch. To reset solar lights, simply press and hold the button for a few seconds, then release. This should restore the light to its factory settings and potentially fix any temporary malfunctions.
If you’re unsure whether your light has a reset button or how to locate it, refer to the manufacturer’s instructions or search online for how to reset solar lights of your specific model. While not all solar lights have a reset button, it’s definitely worth checking if you’ve tried everything else.
Conclusion
By checking each of these possible problems one at a time, you should be able to figure out why your solar lights aren’t working and hopefully get them to work again.. If none of these solutions work, it might be time to consider replacing the batteries, the solar panel, or even the entire light fixture. But with a little patience and troubleshooting, you can often bring your solar lights back to life and continue enjoying their eco-friendly illumination.
