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.aitsolarpanels.com
With the rapid development of LED strategic emerging industries, many technologies are still immature and stable. The products on the market are then refilled, and the phenomenon of fisheyes is more common. Therefore, the introduction and implementation of LED lighting benchmark system is very important to promote the development of the LED industry.
Reporter: What is the benchmarking system for LED lighting products?
Li Zili: The benchmarking system of LED lighting products is a reference to Germany's benchmarking enterprise management concept. It is based on the principle of voluntary corporate selection and delivery of products where LED lighting products comply with national security and EMC standards and 3C certification (if the product falls within the scope of CCC). Sampling for testing. According to the test results, the best ones are selected, and the grades are recommended according to the score. It is innovative and advanced. The benchmarking index is more flexible than the standard and can be updated at any time (currently once every three months) according to the latest performance indicators. It is a complete set of LED lighting product evaluation system.
Reporter: At present, what is the progress of the benchmarking system for LED lighting products?
Li Zili: From 2010, the Department of Science and Technology began organizing the research on the LED benchmarking system. Up to now, 800 LED lighting products from lighting companies in the province have been evaluated for LED benchmarking systems, and a list of recommended products for eight batches of benchmarking products has been released. Now that it has entered normalization, Guangdong Province has stipulated that in the LED public lighting field, Guangdong LED benchmarking system must be used in the recommended catalog.
Reporter: Is there any difficulty in the implementation of the LED lighting product benchmarking system?
Li Zili: Difficulties are certainly there, there are some questions, some of which are caused by doubts about the performance of LED lighting products and the development trend is not comprehensive. There are also doubts about the LED lighting benchmarking system implemented in Guangdong Province. It is believed that this benchmarking system only emphasizes product efficacy (energy efficiency). In fact, Guangdong Province has conducted a lot of studies on the design and parameter setting of the LED lighting benchmark system. (At that time, the participants of each unit's research team had a total of five or sixty discussion sessions once a week), and the inspection items set up included Some of LED lighting's items of concern include indoor LED lighting products such as comfort, color uniformity and color difference, and actual use effects such as LED street lighting tunnel lighting products according to the road conditions, brightness uniformity and environmental ratio, etc. . Of course, the rapid development of LED technology, the benchmarking system also needs to continue to improve the place, can not be fully blamed. For example, the automotive industry has developed for more than 100 years, and sometimes it will still be recalled in large quantities. This phenomenon is normal in all industries.
Reporter: This year, Guangdong has launched a new version of LED lighting benchmarking. What is different from the old version?
Li Zili: First of all, it revised the Guangdong Guangdong LED lighting product evaluation benchmarking system management standard. In addition to improving the LED street lamp, LED interior lighting benchmarking system management specification, also formulated the LED tunnel lamp benchmarking system management specification and other LED lighting products (miscellaneous ) Benchmarking system. For the existing problems in the benchmarking system evaluation, for example, although the benchmarking system sets a high threshold for sample quantity and sampling, there are still companies that provide products for inspection and cost that are much higher than the actual amount in order to obtain good evaluation scores. Produced products, evaluation results can not reflect the actual use of factories and lighting projects. Therefore, the new version of the LED benchmarking system management specification has increased the factory inspection, product consistency check, and the highest price of the proposed benchmark product. At the same time, the testing organization participating in the benchmarking system has been identified using tenders and on-site inspections.
Reporter: The LED lighting product benchmarking system is only applicable to Guangdong Province. Will it be promoted throughout the country in the future?
Li Zili: This is what Guangdong expects. However, it is also difficult to promote the country as many places have their own policies. However, Guangdong's LED lighting product benchmarking system has great influence in the country. Many people know the benchmarking system in Guangdong Province. However, they do not know the specific content and do not know how to understand it. Therefore, LED lighting benchmarking system needs to strengthen publicity and promotion.
The research and implementation of the benchmarking system lays the foundation for the formulation of industrial standards. Although the LED standard is continuously improving, many standards cannot replace the benchmarking system. The standard is the threshold for product technology and product quality, and the LED benchmarking system is a kind of In pursuit of superior scientific evaluation of product quality on the basis of compliance with mandatory standards. Therefore, it is of great significance to continuously research and continuously promote the LED benchmarking system.
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.
