When solar lights are brand new, they seem like a terrific idea, but you may have to restore outdoor solar lights when not working. These easy-to-install lights use solar cells to convert sunlight into electricity, which is then stored in batteries to power the lights.

Solar-powered lights, however, have a few flaws that may make them less dependable over time. The most severe problem is a clogged solar panel, which is relatively simple to repair.

First, you should examine your solar lights to see whether they are broken. Cover the solar panel to make it appear that it is night, causing the lights to turn on if they are operable.

Solar lights operate in such a manner that it is turned off when there is enough direct sunlight. This period is utilised to charge the batteries and build up an energy reserve.

When it gets dark, the energy is used to power the lights. If your solar lights aren’t working, another light source may be shining through the panel, providing the misleading appearance that it’s still sun. Seasons change might also affect the functioning.

Sometimes, the solution is as easy as rotating the panel slightly to ensure that the panel’s day or night reading is accurate. You tried moving the lights to a new location, but it didn’t help. It appears like your lights are malfunctioning.

If your solar lights stop working, here are some tips to help your grubby solar panel get back to work.

Tips for Repairing Your Solar Lights

Cover The Panel

When the solar panel is covered, the lights are fooled into believing night has arrived early and turned on. During the day, solar lights are usually turned off automatically since they convert light into energy to be stored in batteries.

At night time, this energy is needed to keep the lights on. If your light hasn’t turned on after night, cover the panel; if it does, you’ll know another source of light hitting the solar panel, fooling it into believing it’s still daytime.

A small adjustment to the panel placement will sometimes correct the problem and get your solar lights to work properly again.

Replace The Batteries

Solar LightDid you realise that new solar lights frequently contain standard rechargeable batteries? Modern products should always be rechargeable, such as NiMH or Li-ion batteries.

Because the solar light batteries charge throughout the day and drain at night, they will eventually lose their charging ability when the light is turned on. Even after a sunny day, reduced runtime in the evening hints that something is occurring to your lights.

Good batteries should last for at least one to two years before you need a new battery, although this is merely a guideline. If you discover dead batteries, you must replace them with new ones.

Some customers report that their many solar lights have been on for over six years and are still using the original batteries; however, this is the exception rather than the rule.

Ensure your normal batteries haven’t fallen free from their strip, which is another simple check. They won’t be able to charge if they don’t touch the terminal’s contacts. If you discover a loose battery, give it a couple of days to recharge before using it again.

Check For Water Infiltration

Water penetration or water ingress may cause damage to solar lights on occasion. This shouldn’t be a problem if your light is properly designed and constructed.

Your product’s ingress protection (IP) rating indicates how effectively it is protected against moisture. For the greatest possible protection, choose one with a high IP rating.

Water may not always be a problem since many units can let water flow off without contacting the electrics, but if it is, there are a few things you may do to fix the problem:

Remove any covers retaining moisture and place the lamp in an airing cupboard to dry it for a few days. Please put it back together, ensure the batteries are in the right places, and then charge the light for a few days before using it again.

Always read the manufacturer’s directions before doing anything—a properly installed solar light with a guarantee may contain a water ingress restriction.

It implies you may get your light changed by just contacting the manufacturer. You may be asked to give photographic documentation of the problem.

Hungry Squirrels

Customers occasionally bring us photos of creatures that have been hungry and help themselves to some nutritious wire from a string of fairy lights, for example, hungry squirrels.

Solar Garden LightsElectrical tape and patience are sometimes enough to fix the damage. If this isn’t feasible, contact the manufacturer to see if spare parts are available to avoid disposing of the entire product.

When it comes to wire, always leave plenty of slack between branches in any installation where the wire may be subject to strain, such as a string of fairy lights in a tree. Extreme weather can put undue strain on the wire, creating broken wires that are difficult to locate and much more difficult to repair.

Clean The Solar Panel

The best approach to clean solar panels is using pure water. If it fails, you can use rainfall or low-mineral-content tap water.

Why?

Do not use soapy water. Soaps might leave a film or residue behind that promotes grime to stay and accumulate faster. Worse still, washing solar panels with a strong chemical solution might result in scaling. This can penetrate the frame and destroy the silicon.

Soaps and detergents aren’t the only options.

The steps for cleaning a solar panel are as follows:

  1. Choose the best time of day for you – when the sun rises or evening is ideal.
  2. Pre-rinse – removes the dirt and debris from the first layer.
  3. Scrub – use a gentle yet abrasive scrub.
  4. Last but not least, rinse away any leftover dirt and debris.

Allow them to dry if you use just pure water naturally. This is because pure water leaves no residue or pollutants behind.

Outdoor Solar Lights

This can happen if your solar lights are entirely or partially shaded by glass, such as a patio or outdoor room’s glass roof. It can also happen if you charge your solar lights before a window.

While we may be able to benefit from the sun by sitting near a window, the same cannot be said with solar panels.

Modern glass has double or even triple-glazed windows to shield people from harmful radiation. However, it renders the sun’s rays worthless when they strike the solar panel, as it only gets passive infrared rays.

Solar panels need enough sunlight and cannot be charged by disappointing light. The ideal spot to put the panel is always outside. To completely charge it, place it somewhere with plenty of direct sunlight.

Inspect The Solar Light

Verify that the solar lights’ switch is firmly plugged and fully in the “on” position. The switch for a solar landscape light can be found on the bottom of the solar light capsule or under the cap.

Solar Garden LightOn certain versions, release the cover from the clear plastic section of the light by turning it counterclockwise.

Set the solar lights in a place where they will receive sufficient sunlight. Please place it in the right direction and at the best angle, facing the sun for many hours after making sure the switch is on, then test it by covering the solar panel with your palm.

The electrical connections between the panel and the lamp may be corroded by moisture within the light, and they can affect the specific voltage needed for the solar lights. It can also affect the batteries. Keep an eye out for corrosion.

You may be unable to repair outdoor solar lights that have stopped operating due to excessive corrosion. You’ll have to get a new light instead.

Check the cable to see whether it’s still in excellent shape if your solar lights are on a string, similar to street lights. Animals have been known to gnaw through the cable. In a rush, you might be able to mend the string light wire by taping the bare portions of each section of the line using electrical tape.

Replace a Faulty Sensor

Solar light sensors might fail for a variety of reasons. The most typical cause for a sensor failing is that it is old and has to be replaced. As with anything else, if something is used frequently enough, it will ultimately break down and must be replaced. A light sensor on your solar light is the same way.

Another possible cause of a defective lux sensor is that it has been damaged somehow. The sensor can be jarred and stop operating correctly if it has been knocked over too many times or struck with anything fairly hard, leaving you with a broken solar light.

A defective sensor is one of the most common causes of your solar light turning on during the day. It may malfunction if you’ve cleaned and dried the sensor well and it’s still turning on during the day.

The good news is that they are virtually always replaceable. If the remainder of the solar light is in fine working order, you can contact the manufacturer to see if replacements are available. This is not just a quick remedy for a solar light that turns on throughout the day, but it’s also a cost-effective option and a great idea.

Turn It Off For 72 Hours To Charge

Your solar light is hard at work converting the sun rays into energy that can be stored in the battery until dusk. Sometimes, you must give your solar light a ‘break’ to recharge and regain its vigour and vitality.

Box of Solar LightsWhen preventing your solar light from turning on during the day, this is, of course, the final measure. If you’ve done everything else and it still doesn’t work, consider giving it a 72-hour break.

Switch off the solar light completely. You might also want to take the battery out of the solar light and store it in a dark room with no light sources so it doesn’t start charging again.

You can try reassembling the solar light after 72 hours to see if it was the solution to your solar light turning on throughout the night.
