In recent years, the Quality Supervision Bureau, the General Administration of Inspection and Quarantine, and the Bureau of Industry and Commerce have conducted spot checks on LED lighting products, energy-saving lamps, road lighting, fire emergency lighting and electric light sources throughout the country. It was found that the pass rate of LED lighting products was only 51%, and the inferior quality was worrying. Fan Ningning, President of Shenzhen Changyuntong Optoelectronics Technology Co., Ltd. Fan Ningning, president of Changyuntong Express, said: "This phenomenon is true. Some companies use imitation products or poor materials for low-cost dumping, which can reduce costs. However, this will definitely affect their own credibility and will also Bring adverse effects to the LED lighting industry. This requires the joint maintenance of the entire LED industry enterprises, and the government must strengthen supervision. " In addition to quality issues, the biggest obstacle to LED lighting is price. "Compared with traditional lighting, the market share of LED lighting products is only 5%." Fan Ningning told reporters that the bottleneck is that prices are still high. The development of LED in the mainland is relatively short. Only a few years, the rapid decline does not conform to the law of development. At present, for a good enterprise, the cost of a 5-watt bulb is 2 US dollars, which is about 15 yuan, but most of them are around 20 yuan. There is still a 30% drop in domestic LED lights. From 2013 to 2014, it is basically no problem to achieve popularity. LED lighting is composed of core parts such as light source and driver. It is reported that at present, Long Express is involved from packaging to driving to lighting, and there are tens of thousands of shipments per month. Because the LED driver IC is independently developed, the quality of the driving power is very stable, the process factors and the photoelectric conversion efficiency are very high, therefore, the LED lamps of Changyuntong have advantages in price. At present, the 5W bulb lamp of Long Express can be sold for about 18 yuan, which is much cheaper than other 25-26 yuan. International big brands sell for 6 dollars, and they sell for 10 dollars in supermarkets. According to Fan Ningning, the price reduction of the bulb lamp is inevitable within two years, but it must comply with the law of market development. The price reduction caused by the increase in market demand and technological progress is more rational. The price reduction caused by vicious competition and the premise of sacrificing product quality Price cuts are unhealthy. According to reporters, in 2013-2014, driven by market demand and government policies, prices fell to a level acceptable to the general public. At the same time, in this round of reshuffle of the fittest, the fake and inferior products will be cleared out, and the low-cost and high-quality LED products will gradually go to the public. Polycrystalline silicon solar panels are a common type of Solar Panel whose main function is to convert sunlight into electricity. The following are the main functions of polycrystalline silicon solar panels: polycrystalline silicon solar panels, poly crystalline solar panel, polycrystalline pv solar panel, polycrystalline pv module, polycrystalline solar module Ningbo Autrends International Trade Co., Ltd. , https://www.china-energystorage.com
Photoelectric conversion: Polycrystalline silicon solar panels are made of polycrystalline silicon material, and their surface is covered with multiple silicon crystals, which can absorb photons in sunlight. When the photons are absorbed, they release electrons from the silicon crystal, creating an electric current. This process, called photoelectric conversion, converts the energy of sunlight into electricity.
Power generation: The current and voltage generated by polycrystalline silicon solar panels through photoelectric conversion can be used for power generation. Multiple solar panels are combined into a solar module, and a solar array can be formed when used on a large scale. These battery modules and arrays can absorb large amounts of sunlight and convert it into electricity to supply the grid or be used to power equipment.
Renewable energy: Solar panels use sunlight to generate electricity and are therefore renewable energy. Sunlight is free, widely distributed, and not exhausted, so the use of solar panels helps reduce dependence on traditional energy sources, lowers carbon emissions, and is environmentally friendly.
Noiseless: Solar panels have no mechanical moving parts, so there is no noise during the power generation process. This makes them ideal for use in residential areas, schools, and other places where a quiet environment is required.
