Seeing how popular solar lamps are on the market today, most of you have probably used them for indoor or outdoor lighting. We all know solar lamps are indeed a type of lamp that offers many advantages, especially in terms of saving electricity costs. However, do you already know about how solar lamp works and how long it last? If not, you can read the information below.

In simple terms, solar lamps work with the photovoltaic effect. The main component of a solar lamp is a photovoltaic cell (also known as a solar cell). This cell is located on the black panel above the solar lamp and is in charge of converting sunlight into direct electrical current. Each solar cell consists of several layers of chemical and crystalline silicone that produce layers of negatively charged electrons and positively charged spaces.
When sunlight enters through the solar cell, the negative-charged electrons will be stimulated and will be pushed into the positively-charged spaces. After that, the positively charged space will transfer the electron stream as a direct current of electricity through the cable system embedded in the solar cell to the battery, where the electricity is stored until the time comes for it to be used. The battery will continue to charge as long as there is sunlight that is collected and converted into electricity.
When the sun begins to set until night falls, the solar cells will stop converting sunlight. At that time, the photoreceptor on the lamp will detect dark conditions and will turn on the light, which usually consists of several LED lights. The battery will supply electricity to the lamp for all-night lighting.
That is how solar lamp works on a daily cycle. Please note that sufficient sunlight is required to fully charge the battery. In summer, this is very possible because the sun usually shines all day. As long as the panel is not blocked by something that prevents it from collecting sunlight, of course, the battery will be easily fully charged. However, this may be difficult in winter, where the nighttime is longer than the daytime. Solar lights may find it difficult to receive enough sunlight to charge the battery, so they cannot stay on all night.
Generally, high-quality solar lamp products use LED lamps that can last for 30 years. As for the battery, the battery needs to be replaced with a new one after 2 or 3 years of use. Because its performance has decreased.
As for the pole and lamp body, they are made of weather-resistant materials so they are very durable. However, solar lamps are not designed to be strong enough to handle heavy snow or freezing temperatures. Therefore, storing the solar lamp in a sufficiently warm and protected place during the extreme winter is recommended, or it may be damaged.
How solar lamp works and how long it lasts also depend on the cleanliness of the panels. You have to clean it regularly so that the solar lamp can produce the maximum amount of energy. Thus the lighting hours will be longer. You can simply clean it by wiping the panel surface with a clean cloth every two weeks.
In addition, choose only high-quality solar lamp products to use. Using cheap products will only make your money wasted. It is a well known fact that cheap products usually do not work well and do not last long.
To find out which product is of high quality, you just need to check the manufacturer. If the manufacturer has a good reputation and is professional, you should not hesitate to buy the product.
For example, the solar lamp products from SDD Light. Not only available in a variety of styles according to function and size, but all of the products are also made of high-quality, weather-resistant materials and under the Electric Security Standard of Europe and America. They also have passed international CE and RoHS, FCC certifications. This means that SDD Light lighting products are guaranteed to function properly and have good durability.
FYI, although using solar lamps can save electricity costs, the initial costs for purchasing and installing are quite expensive. So, make sure the product you choose is worth it and doesn't make a loss in the future. How solar lamp works is very dependent on the quality of the product.
