Solar street lights, which operate from dawn to dusk, are the most efficient outdoor lighting system. They use no electricity and only renewable green energy. Solar street lights are now more affordable, practical, and possible with the latest technology. A solar street light consists of the following components: solar panel, light source and rechargeable battery; charge controller; interconnecting cables.
A solar panel made up of multiple solar cells has one main function: it absorbs solar energy and converts it into electricity that can be used to light the streetlight. The photovoltaic effect is the name of this process. The type and wattage solar panels are key factors in the performance of a solar streetlight. Additionally, the size of the solar cell determines the amount of electricity produced. Solar street lights are often made from monocrystalline and polycrystalline solar panels. Panel efficiency can also be affected by the mounting location and the installation area. The best solar panels convert at a high rate when there is enough sunlight. Most solar panels last between 25 and 30 years.
A battery is used in solar street lights to store converted electric energy. This power can then be used to illuminate the source at night. Modern solar street lamps use either LiFePO4 or lithium ion batteries. These batteries are known for their durability and backup power. Lithium batteries are light and compact, making them a great choice for solar street lighting. Solar street lights that have a high storage capacity will continue to light up even in rainy conditions. Lithium batteries are not like lead acid batteries. Knowing the type, amperage hours, and voltage can help you select the right light.
