With the continuous progress of new energy technology, solar technology, especially the conversion efficiency of solar cells, is also constantly improving. Solar lights including street lamps, wall lamps, wall washers, etc., are more and more widely used in people's lives. They are convenient and energy-saving. So, what are solar lights? What are the differences between solar lights and ordinary electric lights?
Solar lights could be simply defined as the lamps powered by solar energy. They converts sunlight into electricity and stores it in the battery during the day, and automatically emits light at night. A solar lamp is generally composed of photovoltaic panels, fixture, LED light sources, solar batteries, and a controller. Solar photovoltaic panels are mainly used to absorb solar light and convert it into electrical energy. Solar panels are the core part of the solar lamp, and they are also the most valuable part in the lamp. Its main function is to convert the radiation energy of sunlight into electricity before sending it to the battery for storage. There are three types of solar panels that are more common and more practical than others: monocrystalline silicon, polycrystalline silicon, and amorphous silicon panels. Besides, solar batteries could be generally classified in three groups: maintenance-free gel batteries, lead-acid batteries and lithium batteries. Lithium batteries are preferred customers due to t heir various excellent features, such as high charge and discharge depth, long service life, light weight, and small size. Most solar lamps are equipped with lithium batteries. In Mistei Lighting, all solar lamps use lithium batteries to ensure they could bring convenience to customers for their excellent features. LED lamp beads, usually used as light source in a solar lamp, are safe and durable because they have no filament, no mercury and other harmful substances. Besides, their service life is as long as 50,000 hours. The lamp controller is another important part since it could manage the lighting modes, time and protect the batteries, such as preventing them from the damage of over-voltage, under-voltage, over-current, overcharge, and over-discharge.
Main differences between solar lights and ordinary electric lights
- Different lifespans:The lifespan of solar lamps is much higher than that of ordinary electric lamps. Almost all components of solar lamps could outlive their counterparts in ordinary electric lamps. The service life of solar cell components is about 25 years; the average life of low-pressure sodium lamps is 18,000 hours; the average life of low-voltage high-efficiency trichromatic energy-saving lamps is 6,000 hours; the average life of super bright LEDs is more than 50,000 hours; -5 years; 3-7 years for 38-150AH.
- More money could be saved from solar lamps than ordinary electric lights. Once installed in right places, solar lamps will cause 0 electricity bills, 0 wires to connect and very few maintenance fares. Much more electricity and maintenance costs will be saved. In other words, using solar lamps means one-time investment but many long-term benefits. It’s estimated that the first-time cost will be recovered in 6-7 years. On the contrary, ordinary electric lights have complex circuits which need long-term continuous maintenance. Especially in the case of unstable voltage and currents running in those fragile sodium lamps, it is inevitable to spend much money to maintain and fix them to extend their service life.
- Solar lamps are safer than ordinary electric lights. Low and stable voltages (12-24V) are commonly used in solar lamps, which makes their working reliable and safe. No potential safety hazard will take place. Particularly, solar lights are ideal for ecological communities and road administration departments.In those ordinary electric lights, however, many hidden dangers could hide since they are close to people’s living environments and constantly changing weather conditions could wear out their exterior. Road reconstruction, landscape engineering construction, abnormal power supply, and cross construction of water and gas pipelines, unexpected storms and hurricanes could put them in risk.
- Differentinstallation: When installing solar lamps, it is not necessary to set complex lines, but only to make a cement base and a battery pit within 1 meter, which can be fixed with galvanized bolts. There are complex operation procedures in the construction of ordinary electric For instance, a large number of civil works, such as auxiliary cables, trenching and pipe laying, threading in pipes, back-filling and so on could consume a lot of manpower, material resources and financial resources. Finally, we need to debug the wiring connection. Once a problem occurs, it will cause a lot of waste. In modern times, the solar lamp is the most ideal lighting solution for our houses and business properties. It is convenient and beautiful, and will not pollute the environment or cause some potential problems to us.
- Different meanings to the entire human society: Compared with ordinary electric lamps, solar lamps have more far-reaching and positive significance for the development of human society. Since the power of the solar lamp comes from the clean and pollution-free sunlight that will not be used up,people use the lamp for generations. Solar lamps can help mankind achieve sustainable development in the true sense. The electric energy of ordinary electric lamps comes from consuming the limited resources on the earth, especially fossil energy, while producing much environmental pollution, which is not conducive to the sustainable development of human society. To conclude, solar lamps could help people achieve the goal of sustainable development so that our future generations could live in a pollution-free world.
Conclusion
With the continuous improvement of modern technology, solar lamps, as the most common and simple form of solar energy resource application, are getting more and more sophisticated popular. Compared with ordinary electric lights, they enjoy many advantages, which can bring more benefits and convenience to people. Mistei Lighting recommends solar lamps to you, hoping that they can make your life more convenient and enjoyable.
