Can Solar Lights Last Forever?

Even the highest quality materials don’t last forever. No matter how glorious these solar lights look, they do have an expiry date. So, how long can solar lights last?

The batteries in the solar lights will give you three to four years of service. On the other hand, the LEDs in your solar lights can run for as long as ten years before requiring replacement.

A long shelf life ensures that you don’t have to face replacement hassles for years. Even so, replacing the batteries of your solar lights is relatively straightforward.

With LEDs in your solar lights, you can stay assured of a decade without worrying about a replacement. The lifespan of LEDs and batteries gives solar lights an edge over other power sources.

Solar lights are also useful because you can leave them lit all night long. They can illuminate your outdoor spaces if they receive strong sunshine throughout the day.

However, you need to maintain them well if you want these lights to serve you as expected.

How Long Do Solar Lights Last?

In the previous section, we gave you a generalized idea of the lifespan of a solar light. But, several other factors determine the longevity of your solar lights.

Different components of your solar lights might need replacement from time to time. These complex devices have several parts that affect their lifespan, lighting, and power. Here’s everything you need to know about solar lights.

How Long Do Solar Lighting Batteries Last?

Most commonly, solar-powered lights use a rechargeable battery. The panels absorb sunlight and convert it into consumable energy. They then transfer this converted energy to a battery unit and fuel the LED lights.

These batteries have a lifespan of nearly four years. But, the lasting of your battery will also depend on its maintenance and other components.

We advise you to stock some rechargeable batteries beforehand for a hassle-free replacement. The lasting of the batteries will also depend on your consumption frequency.

How Long Do Solar Lighting Panels Last?

Solar panels play the role of charging the batteries in the setup and do not directly power the lights. Nevertheless, maintaining solar panels is equally essential.

Damaged solar panels will dramatically alter the lifespan of your solar panels. It would help if you cleaned these panels often. Make sure that the panels receive direct sunlight. Also, the panel should be free of any obstructions.

Unobstructed panels absorb sunlight better and do an excellent job of charging the batteries of solar lights.

How Long Do Light Sensors Last?

Another critical factor that determines the overall lifespan of your solar lights is the light sensors. Most people overlook the condition of the solar light sensor. It is responsible for detecting the surrounding light levels.

If the sensors detect substantial sunlight, they will automatically stop illuminating the LED lights. Due to obstruction, the sensor might not be able to detect light. As a result, it’ll keep the light switched on all day long.

Such situations will end up draining your battery unnecessarily. Further, this can significantly reduce the overall lifespan of your solar lights.

How Long Does the Casing Last?

The quality of the casing can save your solar lights from deterioration. The plastic or glass casing of the solar lights is the most durable and versatile part of its structure.

Without proper and durable casing, it’ll be easy for the dust and debris to infiltrate and hamper the performance of your solar lights. Therefore, keeping the casing of your solar lights clean and damage-free is the way to go.

How Long Do LEDs Last?

You’ll notice that most solar lights these days use LEDs. Why? It is because LEDs have a long-lasting and much more effective performance. These lights are more cost-effective and energy-efficient.

LEDs last at least ten years before requiring a replacement. In some cases, they might even serve you for as long as 30 years.

So, if the LEDs are not damaged or cracked, it would not hamper the longevity of your solar lights.

How Can I Improve the Lifespan of Solar Lights?

Now that you know the lifespan of different components of solar lights, it’s time to look at them as a whole.

There are a couple of secrets that can help you prolong the life of your beautiful solar lights. Handling them irresponsibly and not maintaining them will only shorten their lifespan.

Harsh weather and outdoor conditions can take a toll on your solar lights. Though no solar lights last indefinitely, proper care can boost their lifespan.

So, if you’re wondering about tricks that can notch up your lights’ performance, we have some for you!

Keep a Stock of Replacement Batteries

By now, you must have understood that batteries are an indispensable part of solar lights. These rechargeable batteries power themselves using direct sunlight.

Though these batteries never run out of power, they might degrade over time. Harsh weather conditions also take a toll on their durability.

Eventually, the batteries will diminish in their capacity to take and store power. When the batteries degrade, they become unreliable and malfunction. Therefore, we advise you to keep a spare set of batteries for your solar lights.

Though the batteries have a lifespan of up to four years, changing them every couple of years is recommended.

Clean Them Regularly

Cleaning always has benefits for electrical devices. The dirt and debris accumulating on your solar lights can alter the lifespan of your solar lights. Outdoor solar lights require more care and maintenance as the weather can be harsh on them.

Cleaning and maintaining them will help the lights to function properly. Try to clean the lights at least once a month.

Besides, solar lights cannot perform well with the layer of dirt on them. For instance, the dirt and debris on solar panels might obstruct solar panels from receiving sunlight.

Position Them Away From Clutter

The placement of your solar lights is another factor that affects their lifespan. Do you know that your solar light might last longer if they have access to direct sunlight?

Placing the solar lights near the house or the hedges and fence is one of the most unfortunate mistakes. Though it might encourage aesthetics, it can cost you.

Placing the solar lights near structures or your house prevents access to direct sunlight. The structures cast a shadow that might not be an ideal charging condition for solar lights.

Carefully analyze your outdoor area before placing your solar lights. Once you note the shadow-free and open spaces, you can go ahead and fix your lights.

Use Override Switch

If you have recently bought a solar light, the chances are that it has an override switch. Most modern-day solar lights include an override switch. It is essentially a power switch that overrides the light sensor.

If you want to improve the lifespan of your LEDs and lights, use this switch during rain or overcast weather.

During the winter or poor weather conditions, the solar lights might not perform well due to insufficient sunlight. Therefore, you can preserve power by manually turning off the lights.

Snow and rain are the most unfavorable seasons for batteries. Hence, this tip can save your lights from significant damages.
