Do Solar Lights Stop Working?

There is massive wrong information out there about solar lights and how they work. Some people even think that the sun's energy will eventually run out, causing solar lights to stop working. Luckily this isn't true!

When you buy solar-powered outdoor lighting fixtures, the power comes from an internal battery that recharges during the day with help from sunlight. The batteries are generally lithium-ion or nickel-metal hydride, which can last for several years without needing replacement. So please keep on learning more about how your light works and why it's so great!

 

How Do Solar Lights Work

A solar-powered lighting fixture has two main parts, a solar panel, and an LED light. The solar panels that installed on top of the fixture to catch the sun's energy. You can position them either facing south to get maximum sunlight or facing east/west for all-day charging. Some lights come with two solar panels on top, allowing you to position them in either direction.

While the solar panel collects the sun's energy, it's also charging the battery inside the fixture. The solar panel works like a small generator and transfers power into an electrical current that charges the batteries.

 

Do Solar Lights Need Direct Sunlight To Work

It depends on the type of fixture you have. The most common style is a simple light that requires full sunlight to illuminate. These fixtures are best for lighting up walkways or any other area that gets plenty of direct suns. If there are shady areas where you want the lights, consider getting lights with motion sensors.

 

Do Solar Security Lights Work At Night

When you're outside in the dark, and an intruder is near, you don't want to see him approaching before he gets too close. Unfortunately, a standard fixture isn't very effective for this since it won't work until it's fully charged by the sun.

It is why solar security lights are the best choice for anyone looking to keep an eye on their property after dark. A motion sensor will activate these lights when it senses something moving nearby, and they stay lit for about 20-30 minutes, giving you plenty of time to investigate any noises or movement near your house.

 

Do Solar Light Batteries Die

You'll pay around $10-$20 for a solar light that comes with one rechargeable battery, which should last approximately 3-4 years. It may be tempting to replace the battery yourself after it dies, but you should keep in mind that most batteries are sealed and aren't designed to be opened and returned. If you open the fixture up yourself, you could end up breaking it or short-circuiting the battery. In many cases, you'll need to buy a new light fixture altogether at that point if you can't find a replacement battery for your model.

 

What Happens To A Solar Light At Night

The answer is simple. When the sun goes down, and with it, the power from your LED bulbs disappears in darkness. And because it's dark out, you don't see much of anything. So all that energy stored in a highly efficient battery is being wasted! Not anymore, though.

This new solar-powered spotlight not only recharges during the day but also turns on automatically at night. So it's an easy way to get your backyard ready for a party or your deck lit up without doing much work yourself.

 

Why Do Solar Lights Stop Working After A Few Weeks

Brace yourself because it's not the product, but you're doing something wrong. 

  • First of all, we are talking about solar-powered lights, so sunlight is required. If you live in Alaska or a winter island with no sun for half of a year, you should use another energy source such as batteries or connect to the grid.
  • Second, sunlight is not enough for solar lights. It's the same as human consumption. How much would you talk if you don't eat and use light? Maybe 2-3 minutes only before your lips turn blue, then how about a solar panel? I am sure it can last longer than 10 seconds in the shade.

 

Simple Analogy

If you find it hard to understand, let's use a simple analogy. Consider solar panels as a human body; sunlight is food, and energy is health status. If food isn't enough, then your health will drop immediately—the same with solar panels – the more sunlight it receives, the higher output voltage and current.
