Why Do Outdoor Solar Lights Stop Working?

Solar lights offer an eco-friendly alternative to conventional lighting that’s cost-effective and efficient.

But these lights can sometimes experience issues and stop functioning suddenly and unexpectedly, leaving users without an illumination solution.

Solar lights can become damaged over time from being exposed to the elements, but there are a few easy steps you can follow to restore them if they begin malfunctioning.

If your solar lights have stopped working properly, it could be because their batteries have lost their charge. Solar lights use batteries to transform solar energy into electrical energy which powers the light at night; during the day the light stays off to ensure its batteries don’t drain prematurely. If a newer solar light has been in your yard or garden since last summer, however, its possible its battery has lost charge over time; fortunately it can easily be fixed.

As well as making sure the battery is properly seated, make sure its seating strip hasn’t come loose, as sometimes this happens and must be pushed back down. Also ensure your solar light isn’t being shaded by trees, buildings, or structures on your property as this could prevent its illumination – sometimes this causes it to not come on at all! If it still won’t light up it may be because another light source nearby is misleading it into believing its daytime hours still apply so cover the solar panel to see if this helps rectifying this issue!

Alternately, moisture could be causing your solar panel to malfunction improperly; in this instance it would be important to contact the manufacturer to ascertain eligibility for replacement under warranty.

Sometimes solar panels become cloudy and stop absorbing sunlight effectively – particularly inexpensive landscaping solar lights. To remedy this situation, clean the panel using a damp cloth before applying clear nail polish to help it absorb sunlight more effectively.

Make sure that your solar lights are not being obscured by fences or sheds as this can prevent them from soaking up enough sunlight for proper functioning. If this occurs, simply moving them to another area should help restore their full potential performance. Alternatively, using a timer could also help.


Solar lights use solar cells to convert sunlight into electricity for use at night, with photosensors being used to trigger the light when darkness is detected. While these devices can be convenient and effective, occasionally problems may arise that need resolving quickly – here are a few simple solutions that may help get them up and running again as planned.

Prioritize checking if the batteries are functional or dead. Solar lights often lose battery power over time without you being aware of this; this could be caused by leaving the lights turned on overnight without turning them off manually, weather conditions or squirrels chewing through wires.

Check your solar panel itself. If it has become covered with debris such as leaves, dirt or mud, this may prevent sunlight from reaching it and cause its light not to turn on. Regularly cleaning off your solar panel to maintain its appearance and ensure sunlight reaches it can help ensure its fullest potential is received by it.

Position the solar light so it faces the sun for optimal results and see if that helps it turn on more quickly. Repositioning can help ensure it receives sunlight throughout the day.

If everything seems fine but the light still won’t turn on, replacing its battery may be the solution. These cells are typically housed under the solar panel assembly and can be accessed using a small screwdriver – an easy and cost-effective solution for solar lights that won’t power on.

Switches or microprocessors inside of the light may also have stopped functioning properly, albeit rarely. If this remains an issue for your light, professional electrician services may need to be called.


Solar lights can save both money and energy as they automatically switch on at night and off during the day, making installation and maintenance simple and minimal. Unfortunately, like all electrical devices, solar lights may stop functioning for various reasons such as dead batteries, burnt-out bulbs, poor sunlight exposure, bad switches or damaged wiring; if any of these problems arise for your solar light please use our tips below to restore its functionality and get it back up and running again.

Start by checking the batteries to make sure they’re charged up, if not replace them immediately. Also consider moving your solar light to an area with better sunlight for maximum absorption and functioning properly.

It could also be the sensor. Fixing this should be straightforward: disassemble and clean with damp fabric free from chemicals before reassembling. Test it by covering it with your hands at night or during stimulated darkness; if the lights come on then everything should be fine with its functioning correctly.

An often neglected issue is when solar panels become covered in dirt or dust, leading them to misinterpret the light as being already bright outside and thus failing to switch it on when night falls. This causes it not to turn on automatically because it deems illumination already present outside.

Assuming your solar light panel hasn’t become discolored from rain, snow and ice exposure, cleaning it with clear nail polish can restore its original gleam. If this method doesn’t do the trick for you, try wiping down its surface with a damp cloth without chemicals; alternatively you could try clear nail polish to refresh its appearance if necessary. It could especially prove helpful in areas with lots of rainfall, snowfall and ice cover where corrosion damages its ability to absorb sunlight. Once complete, reassemble your solar light and it should work normally again; otherwise contact the manufacturer and see if replacement options exist under warranty agreement.


Solar lighting can help save both energy and money on home and garden lighting costs, by harnessing solar energy for use at night. Since solar lights rely on batteries, energy stored during daylight hours is stored away until needed at nighttime – although occasionally problems may arise with them and they stop functioning altogether! However, with just a few simple steps you can restore them quickly!

Solar lights often stop working due to a dead battery, with most using rechargeable Nickle Metal Hydride (NiMH) cells that eventually lose their ability to hold a charge over time. To maintain proper operation of your lights it is vital that you regularly inspect their battery status and replace when necessary.

Solar panel owners frequently report not receiving enough sunlight due to overgrown plants or overgrowth preventing it from reaching their panel. To address this, it is advised to trim back any vegetation blocking the path or relocate the light in order to guarantee adequate sunlight is reaching it.

Moisture inside of a solar panel can cause corrosion and circuit malfunction, but this is usually remedied by wiping it all down with a soft cloth before placing in a warm cabinet for several days to dry completely before reassembling your solar light and checking to make sure all batteries are secure in its sockets.

Sometimes the switch on a solar light may go bad or become stuck, preventing its lights from turning on at night. You should check to make sure it is in the “on” position, and if necessary unscrew and replace with a new switch.

Solar lights are an easy and cost-effective way to add outdoor illumination, yet when they stop working unexpectedly they can be frustrating. By reviewing the six most likely causes for their non-function, you’ll quickly identify any issues and have them back up and running quickly!
