Are Solar Lights Dangerous?

Posted 9 months ago by Kami

Solar lights indeed provide us with extra lighting and ambiance, but can solar lights catch fire?

Solar lights use solar panels to charge the built-in batteries, and here comes the problem because solar lights use lithium-ion batteries, it poses a risk of catching fire.

This actually happens due to the highly reactive materials and lithium salts used in their manufacturing.

Despite the fact that the risk of fire is extremely low, there are a few things to know about solar-powered lightning that can help them last as long as possible while also lowering the already low risk.

Can Solar Lighting Put Off Heat And Catch On Fire?

Solar lights can emit a little amount of heat, depending on the type of bulb used. Although it will not produce nearly as much heat as a regular lightbulb in your home light fixtures, some heat will be generated.

However, this heat isn’t enough to set your lights on fire. When a fire occurs, it’s usually due to the stored energy in the batteries from the sun.

Batteries made of volatile or low-cost materials can produce more heat than they are designed to, causing the housing of the light to melt. 

If this housing is near a brush pile or wooden structures, the melting housing’s extreme heat could spark a fire.

Most of the incidents of solar lights catching fire seemed to have a thing in common. Overheating batteries dissolved the light’s case, which melted or scorched anything they were connected to.

Cheaping Out On Solar Lights Will Increase The Risk Of Catching Fire 

Since solar lights are used outdoors many thrifty-minded customers will think that they shouldn’t spend a lot of money on something that will be exposed to the sun, rain, dust, and debris for half of the year. 

Their main purpose is to emit light to illuminate a path or an area of the yard; even inexpensive lights can do the job.

However, low-cost lighting requires low-cost materials and labor. Safety controllers are included in solar lighting that uses Lithium-Ion batteries to help manage the amount of charge generated and prevent the batteries from overcharging. 

Cheaper items either neglect or skimp on these safety features.

How Should You React If Your Solar Light Catch On Fire?

ABC fire extinguishers, water (either from a hose or buckets), bottles of soda, juice, or milk will do the job, Just remember to immerse the on-fire light completely.

Can You Get Electrocuted By Solar Lights?

When purchasing a solar light, the question of can I get shocked by solar lights might come to your mind. 

However, don’t worry!

The power produced by most solar lights is insufficient to cause electrocution. Installing solar lights also eliminates the need to work with live wires, and the housing of the bulb is made of waterproof and shockproof materials that won’t cause any damage.

Why Getting Electrocuted By A Solar Light Is Something Out Of The Question?

To understand why it’s very unlikely to get electrocuted by solar light, you need to know how solar lights work.

Solar lights work in the same way as solar panels do. Each light has a chemical-filled cell that converts sunlight into electricity. The current is passed into a battery, which stores it.

The solar cell’s function is to charge the light battery. When night falls, a built-in sensor detects the darkness and illuminates the light with the stored solar energy. 

And the same process is repeated: the solar power charges the solar battery throughout the day, and the energy is used to power the light in the evening.

Battery storage and cells are found in almost every solar light. Each cell produces only half an amp of power, which is extremely safe given that muscle contractions require 15 times that amount. It will not hurt you if you accidentally touch one of these.

The larger the size of the solar panel the higher the amps and the risk. 

Large PV arrays, on the other hand, are safe since the cells are protected by tempered glass and the systems have built-in safety features. However, you can still get electrocuted if you touch the metal frame.

Do Solar Lights Cause Cancer?

Many homes are unfamiliar with the concept of solar lights, so it’s reasonable if there are some misconceptions.

One of the internet’s most popular myths is that solar lights cause cancer. The supposed reason behind this claim is that solar panels of the solar lights emit non-ionizing electromagnetic (EM) radiation, which some people mistakenly believe is harmful.

It’s not the case. Solar lights don’t cause cancer. 

A properly operating solar system does not generate any more EM radiation than your home’s existing electrical cables.

In any case, there is no scientific evidence linking non-ionizing electromagnetic waves to cancer.

Solar panels also generate direct current (DC) electricity, which does not generate electromagnetic fields as AC-carrying wires do.

Will Solar Lights Deter Deer?

Solar-powered yard lights are a good technique to keep deer out of your yard. 

Keeping these friendly herbivores out during the day might be difficult, but many of the most prevalent deer species are nocturnal.

Because deer like to graze at night, motion sensor lights will come in handy, as deer are wary of anything that appears to be a threat. 

At night, a bright light produces just enough of a fear to keep the deer away.

To the deer, the unexpected spotlight indicates a potentially lethal situation. Their biological flight reaction will be triggered as a result of this.

The light turns on suddenly when it detects the deer’s movement, creating an unpredictable scare.

Do Solar Lights Attract Bugs?

The majority of insects (excluding butterflies) are attracted to lower levels of other types of lighting rather than sunlight. Moths, for example, hunt at night and use light spectrums that aren’t visible.

Insects can see infrared (heat radiated from things) and ultraviolet (light emitted from the sun) at night, giving them a major advantage over creatures who do not. 

Lights have been known to attract even the deadly mosquito (due to the heat and not the light itself).

Unfortunately, man-made light sources (such as halogen, incandescent, and fluorescent) typically emit a broad spectrum of light, including infrared and ultraviolet, which insects detect and attract. 

Modern light sources, such as LED and solar outdoor lights, provide a much narrower spectrum of light (mainly visible light), emit less heat, and hence do not attract insects as much.

One of the advantages of solar lights is that they don’t attract insects. Whether you’re lighting a parking lot or a roadway, outdoor solar lighting is an effective and environmentally friendly lighting solution for any industry. 

Keep the bugs away and your maintenance costs down.

Is Solar Light Good For Plants?

You may be considering if solar lights are bad for your plants, The answer is no, based on what we know about how plants use sunlight. Solar lights are quite unlikely to affect plant growth.

Solar lights appear to be bright, yet they produce relatively little light. 

In comparison to what plants receive from the sun, it’s a drop in the bucket. These artificial lights look exactly like moonlight. There’s no reason to believe solar lights will harm plants if moonlight doesn’t.

The only exception is if infrared and/or UV lights are used. 

Avoid UV and infrared lights since they can disrupt the plant’s normal cycle. 

The good news is that solar lights do not emit UV or infrared radiation, which means your plants are safe.
