Factors that Cause Poor Lighting in Solar Lights

Solar lights have become a fundamental aspect of a modern home’s illuminating system. Notice that most establishments, public facilities, and even residences have solar lightings installed on either gardens or walkways. The purpose of these outdoor solar lights is not only to provide illumination but also to enhance the beauty of the structure.

If you want to redesign the front of your home, garden, or walkway, installing outdoor solar lights is a great idea. Remember, these types of lighting utilize solar energy instead of electricity. Hence, using solar lights help in conserving electricity and save energy bills. Indeed, it is a cheaper way of improving your home’s beauty.

The approximate battery lifespan of a solar light lasts about three to four years. However, the LED of the light has a longer lifespan of ten years. When you buy a solar light, you can replace the battery after four years, and the light will be as good as new.

Unfortunately, on some occasions, solar lights produce low lighting despite being new. Why does it happen? What causes poor lighting on solar lights?

Several factors can lead to poor illumination in solar lights. Here it is.

#1 The Bulb

The bulb of the solar light also determines the lifespan of its batteries. If the bulb has more watts, the tendency is it will consume more energy. Therefore, it reduces the battery’s lifespan, which led to a quick loss of power.

If you are planning to buy solar lights, make sure to choose one with bulbs that have fewer watts.

#2 Battery Dying

If the solar’s LED and the bulbs are working, but it produces low lighting, chances are the solar light’s battery is dying.

As you have read from above, a solar light bulb can affect the battery lifespan. Hence, if the battery quickly dies before reaching its average lifespan, it is best to change the light’s bulb.

#3 Poor Sunlight

A solar light requires sunlight to work. If it is under locations that have poor sunlight, it won’t receive the energy it requires to stay lit all evening.

Make sure the outdoor solar lights are directly under the sun. Also, avoid placing it in proximity to the house and street lights. The electrical lightings could throw-off its sensors causing poor illumination.

#4 Cleanliness

The cleanliness of the solar panels can affect an outdoor solar light’s performance. Dirt and other debris could cover the solar panels preventing it from receiving sunlight.

Keep the solar panels clean to get enough sunlight. Also, clean the panels when it is covered with snow.

#5 General Light Malfunction

If the battery is in good condition and the panels receive sufficient sunlight, but it won’t work, the problem could be inside the solar light.
