Tips to Make Solar LED Lights Last Longer:

1. Adjust the tilt angle of solar panels

Solar panels are found on top of the solar garden lights. Depending on the geographical location and weather conditions can affect the output of solar panels. There are a few simple steps you can take to optimize your lamp’s performance.

To fully charge the solar panels, you should install the lights in an outdoor space where direct sunlight shines for 6 to 8 hours a day.

Care should be taken to install the lights in places where there are not many trees, walls or roofs that can block the solar panels on the lights and reduce the amount of electricity produced during the day.

In addition to making the most of the absorption of energy from the sun, it is possible to adjust some of the tilt angles of solar garden lights such as wall lights, security floodlights, column lights…

2. Regularly prune branches and other small trees

Because lights draw energy from sunlight, any plants or shrubs that block some of the light during the day will need to be cut and thinned regularly to ensure your solar panels are exposed. completely with the sun.

Depending on the growth rate of the plants in the garden or the surrounding bushes, you need to pay attention to regularly prune them, maybe once a month or even more.

3. Notice the battery of the solar LED light

When you have just bought a solar LED light, do not immediately use the device, but let the lamp be exposed to direct sunlight for about 5 to 10 cycles (the cycle is charging during the day and discharging at night). night) to allow the battery to charge to its full capacity.

If your storage battery is not fully charged or the light is not working properly, it may be because your battery is corroded or damaged. Thorough inspection is required to remove that layer of corrosion.

You need the tools to remove your fixture and open the battery case, you can find the layer of dirt on top. A note when using batteries is that if you intend to store the lights outdoors for a long time, it is best to remove the batteries to prevent them from corroding.

4. Cleaning solar garden LED lights

Most outdoor decorative solar lights are placed around the gardens to show the garden paths at night, preventing people from seeing the road but stepping on the trees, flowers at night as well as prevent thieves from peeking into your home. Because of the outdoor nature, the lights can get caught in dust and even bird droppings, which will prevent them from receiving enough light to generate electricity to charge the battery. Therefore, make sure that you check and clean them at least once a month to remove dirt and make them work better.

5. Avoid the light of the street lights

Thanks to the optical sensor fitted on the light, most solar lights turn on and off automatically in the morning and at night. At night, when the outside light level is lower than the value in the sensor’s memory, the solar light is activated and turns on the light supply for your garden.

Conversely, the light will automatically turn off at dawn when the optical sensor detects that the external light level is more than the value in the memory. For the optical sensor to work properly, the solar lights need to be arranged correctly. way. When installing lights anywhere inside the garden, make sure that the device is not placed near other light sources at night such as porch light or street light. If the lamp is placed close to another light source, the device’s optical sensor will react to both ambient light and artificial light at the same time. Patio or street lights will reduce the sensitivity of the photosensor and may even eliminate automatic activation of the lights.

6. Replace the storage battery

Storage batteries used for lights typically last one to three years before needing to be replaced. When you find that your solar lights are not working stably, the lighting time is short, you don’t necessarily have to buy a new one, but instead just need to replace the storage battery for it. Because as far as you know solar panels can last up to 30 years, LED bulbs with an average of 8 hours of light a day, they can last up to 17 years. So you don’t need to worry about these 2 parts much, the main concern is the battery that stores electricity.

The rechargeable battery can be replaced every two years under normal weather conditions. If you live in an area with long winters or extreme weather conditions, it’s best to change the battery once a year.

7. Things to avoid when using

Solar LED lights are a combination of solar energy and high-end led. However, it is a product that integrates many useful features for the process of using or operating. But just like any electronic gadget. Solar LED lights also have a process for using and preserving electrical equipment.

During the transportation of lamps, strong impacts should be avoided. Avoid placing the product under other high-volume goods placed on top. Because of the characteristics of the lamp, it is a fixed installation device to avoid falling and jostling with each other. If you do not pay attention, it is easy to cause the microchip system to be affected. Thereby, reducing product life and lighting performance.


While most lighting systems are designed to withstand different types of weather and climates, they work best when they can receive direct sunlight all day long and there is no danger of rain or shine. blown by the great wind.
