6 Tips to Make Solar Lights Last Longer


The excessive use of fossil fuels happening today isn’t doing our planet any good. We can safely say that switching to a renewable energy source like solar energy is the right thing to do.

So, first of all, thank you!

Using rechargeable solar lights can be expensive up-front. However, in the long run, it’ll save you a lot of money.

But how long do they last?

Here are our top six tips to make solar lights last longer.

1.   Regularly Clean Solar Panels

Too much accumulation of dust and debris can significantly reduce the sunlight-absorbing capacity of the solar panels.

Therefore, frequent wiping of the solar panels’ surfaces can optimize performance and provide long-term lighting. Repeating every two weeks should do the trick.

Also, placing the panels at an inclined angle can prevent the build-up of leaves, bird droppings, and other scraps.

Cleaning solar panels should be even more frequent in areas with higher air pollution. Cities with lots of industrial fumes are at higher risk for dust accumulation than others. So make sure to check the level of cleanliness of the solar panels regularly.

2.   Avoid Street Lights

Solar lights detect low levels of light at night and provide the needed illumination for the place. Therefore, avoid placing your solar lights in areas with strong street lighting or house lighting.

These rechargeable lights have solar light sensors. They’re automatically turned on or off by the sensors. The sensors detect levels of surrounding light.

When the light levels are below a specific value, the solar lights are turned on. At sunrise, they turn off again. If the cycle goes on, this means the sensors are working properly.

Nearby night-time light sources can decrease the sensitivity of the light sensors. So, place your solar lights in dimmer spots to maintain their function for longer durations.

3.   Store During Heavy Winters

Another tip to lengthen the life of your solar lights is to store them during the winter season. Leaving the solar lights out in the long and cold winters can weaken their performance.

Some solar lights can withstand the weather year-round. However, the lack of sunlight for long periods can affect solar lights.

It’s better to store them inside during the winter. For proper storage, there are some points to consider.

The lights should be stored in a dry location at room temperature. They should also be stored in a place where they can receive some house lighting or sunlight to elongate their battery life. The battery needs daily exposure to light to sustain a charge during storage.

The lights shouldn’t be placed in a box. Putting them in a box or a dark room prevents the batteries from holding a charge. This can spoil the batteries in the long run.

4.   Switch off the Solar Lights in the Rain

You don’t have to switch your solar lights off every time it rains. But for long periods of rain or clouds, you should. This will extend battery life and provide the best performance.

Strong wind storms can be a significant threat to solar panels that are covered with glass. They should be switched off and stored inside for protection until the storm is over.

Therefore, it’s important to pay attention to the weather forecast.

5.   The Right Place Makes a Difference

Shadows of trees and buildings reduce the time of exposure to direct sunlight, decreasing the solar panel’s performance.

Place the panels in a position where they can get the most generous amount of direct sunlight during the day.

Also, placing the panels outside the perimeter of the selected area can reduce the incidence of contamination. This way, they won’t be covered by plants or dirt from the garden.

Make sure to pick the right place for your solar lights. If necessary, cut blocking tree branches or make extra adjustments to the installation place.

6.   Know When to Replace the Batteries

Solar lights can last for over 30 years. However, you might need to change their batteries. Changing the batteries every couple of years can help you avoid replacing the solar lights often.

The battery life of solar lights is typically two years. If you happen to live in an area with long winters, you might need to replace the batteries yearly.


Using solar energy is one of the best approaches to help save our planet from pollution. With these easy tips, you can make your solar lights last longer.

The most important tip is also the simplest. Just remember to clean your solar panels regularly.  Plus, proper storage can significantly extend battery life. This way, you can make the most of your solar lights.
