How Long Do Solar Lights Last? The Top 4 Factors

Last Updated:

We’ve come pretty far with modern technology. We recently landed a rover on Mars, we can video chat with each other from almost anywhere in the world, and we even have self driving vehicles!

But impressive is all that is, almost everything made by man breaks eventually and than includes solar products.

How long do solar lights last?

Their viability is dependent on many factors, including maintenance, quality, and the climate they’re used in. However, if you’re looking for the short answer, they’ll probably last you 10-12 years before they need replacing.

What factors contribute to their life & what can you do to ensure their longevity? This article takes a deep dive into everything need to know.

Let’s take a look.

The Lifespan of Solar Lights

The LED lights should last you 10+ years, and fortunately they are replaceable. So if they happen to go out before the panels do you can likely replace or repair them, which can extend the life of your solar lights even further.

As for the panels themselves, they have a lifespan of 25 to 35 years, and even then, their performance would still be well. At this point, people either replace the panels or choose to buy new solar lights.

What Is a Solar Light Made of?

Solar lights consist of a solar panel that collects the sun’s energy and turns it into electricity. In turn, it’s transmitted to the battery, where it’s stored until night time.

Then, that stored energy is used to power your lamp. We usually use LEDs as they give the desired luminance and last ten years without loss of brightness. A photocell also works to switch the light off during the day, which typically saves a huge amount of energy.

How Long Do Solar Lights Last? – The Top 4 Factors

Solar lights, known for their endurability, are considered an excellent investment. Whether you’re using them indoors or outdoors, you’re guaranteed an excellent value for your money. Nonetheless, some aspects impact the longevity and capacity of your solar light.


If your lights are installed somewhere where they’re prone to get covered in dirt or dust, it’s recommended you clean the panels every week.

If grime accumulates on the boards, it acts as a barrier between the sunlight and the panel, so it’s harder for the battery to charge. Otherwise, you can clean the panels every couple of months.


Another factor that can affect your solar light brightness is where you place it. It must not be placed somewhere in the shadow; instead, it should face the sun directly. Also, placing solar lights close to another light source disturbs the sensor, causing a weakness in performance.


If you’re living somewhere where winter is rough and snowfall is expected, you’ll need to take some extra measures to keep your solar lights safe. Since the panels get buried in snow, it’s challenging to receive the sunlight and convert it to electricity.

Also, as the daytime is short and mostly cloudy, the batteries may not fully charge. So, you might want to store the solar lights indoors for protection.


Before thinking that your solar lights have lost their luster with time, check the batteries. The batteries are bound to require a change every three years. So, they might be the reason behind the dimness of your light.

What Are the Advantages of Solar Lights?

Solar lights might not be commonly used; however, they indeed prove their worth. They’re a renewable source of energy. This means a lower cost and a happy mother nature!

On top of that, they’re easy to install and fix since there’s no wiring to trouble you. That also means they’re flexible when it comes to location, as they don’t need a fixed electricity transmission.

You won’t have to worry about the danger of electrocution or power cuts either, making them both reliable and safe!

What Are the Disadvantages of Solar Lights?

Solar lights are affected by the weather. Of course, they still charge when it’s cloudy, but the performance won’t be the same. Also, snow could be a liability. So, make sure you’re living in a place where the weather won’t cause you any inconvenience.

Furthermore, solar lights can sometimes be too bulky, so they might not match your aesthetic. However, they come in many shapes and colors, so you can always find the one for you!

Wrap Up

Solar lights might need a bit of maintenance and good weather to give out their full range. Nevertheless, they charge quickly, and their illumination is ideal. Their ten-year lifespan is quite long, not only to us as consumers but also to the environment to stay harm-free.
