In the past few years, the contradiction between cost and price between upstream and downstream has been in existence for a long time. According to the statistics of the High-tech LED Industry Research Institute (GLII), as of the end of 2012, there were nearly 50 epitaxial chip factories in mainland China, which is the largest number of chip companies in all countries and regions in the world. However, it should have relied on epitaxial chips to monopolize the hidden rules of the upstream high-margin semiconductor industry, but it has encountered nails in the Chinese LED chip industry.
The packaging industry in the middle reaches also has a choice of focusing on packaging or expanding into downstream lighting applications. Although similar cases have been common in the past few years, there are only a handful of real open markets for lighting applications. In the eyes of many industry insiders, packaging companies have advantages in lighting first. Secondly, packaging has a stronger understanding of the application side, better understanding of products, and the ability to make cost-effective lighting products that meet market requirements.
However, it is counterproductive. The development of the lighting application market has encountered a channel bottleneck that LED lighting companies are not good at.
In addition to some companies' one-way extension and expansion to their downstream or upstream, there are also a group of companies who have chosen the entire industry chain integration model. Several listed companies with strong scale represented by Dehao Runda, Guoxing Optoelectronics and Sanan Optoelectronics have chosen the whole industry chain integration. In the view of these enterprises, only by mastering the upstream supply and downstream application market can we better adapt to the brutal competition in the future LED lighting market.
The 10th High-tech LED Industry Summit Forum will be held on June 10th at the Shangri-La Hotel, Pazhou, Guangzhou. Dr. Zhang Xiaofei, CEO of Gaogong LED, will give a keynote speech titled Unstoppable Industry Chain Integration. Whether it is the distortion of the upstream, middle and lower reaches of the supply chain, or the contradiction between the lighting manufacturers and the terminal market, or the choice of enterprises before the vertical integration trend, Dr. Zhang Xiaofei will present them one by one.
After the industry turmoil in 2012, the LED lighting industry has ushered in a good momentum of stabilization and recovery since the beginning of this year. In the context of the industry's improved situation, the number of mergers and acquisitions between the upstream and downstream of the industry chain has increased rapidly. For this round of intensive mergers and acquisitions, it shows that the adjustment of the industry pattern based on industrial chain integration has just begun.
Because with the fierce competition in the market and the sharing of resource elements brought about by economic globalization, the products provided by enterprises are becoming more and more homogeneous, so enterprises can no longer maximize profits by increasing sales prices. Compressing costs and expenses has become the only way to achieve corporate goals.
Although in the eyes of many people, to open up the key points of the industry chain and pursue the operation mode of the whole industry chain, providing high-quality LED lighting products to end consumers is the direction of many companies to bet, but ultimately, success or failure requires process and results to test. .
The main function of the MPPT Solar Controller is to realize maximum power point tracking (MPPT) in the solar power generation system to improve the energy utilization efficiency of solar panels. It is an advanced charge controller that can adjust the output voltage and current of the Solar Panel in real-time to keep the solar panel operating at the maximum power output point.
Main effect:
Maximum power point tracking: MPPT Solar Controller can accurately calculate the maximum power output point of the solar panel by monitoring the voltage and current of the solar panel in real-time and according to the characteristics of the solar panel. It then adjusts the panel's output voltage and current to keep it operating at its maximum power output point, maximizing the solar panel's energy conversion efficiency.
High energy utilization rate: MPPT Solar Controller's maximum power point tracking function can ensure that the solar panel is always operating in the best working condition, making full use of solar energy, thereby improving the energy utilization rate of the photovoltaic power generation system.
Charge control: In addition to achieving maximum power point tracking, MPPT Solar Controller also has a charge control function to protect the battery from overcharge and over-discharge damage.
Differences from other charge controllers:
Maximum power point tracking function: MPPT Solar Controller is a charge controller specially used in solar power generation systems. The biggest difference is that it has a maximum power point tracking function, which is used to improve the energy conversion efficiency of solar panels. Other charge controllers may not have this unique feature.
Energy efficiency: MPPT Solar Controller can improve the energy efficiency of solar panels through maximum power point tracking technology. Other charge controllers may only be able to charge in a fixed manner and cannot achieve maximum power point tracking.
Application scenarios: MPPT Solar Controller is mainly used in solar power generation systems, while other charge controllers may be suitable for different types of energy generation systems, such as wind power, hydropower, etc.
Overall, the main role of the MPPT Solar Controller is to achieve maximum power point tracking, improve the energy conversion efficiency of the solar panel, and protect the battery from overcharge and over-discharge damage. Compared with other charge controllers, it has unique advantages in energy utilization efficiency and maximum power point tracking and is suitable for applications in solar power generation systems.
