Whether it is the level of technological development or the scale of application, the Japanese LED lighting industry is at the forefront of the world. In 2013, the LED lighting penetration rate in the Japanese market broke through 50% in the world. According to the design of the Japanese government, the penetration rate of LED lighting shipments in the country will reach 100% in 2020, far higher than the global proportion of about 70%, and the penetration rate will reach 50%. In other words, five years later, of the nearly 1 billion lamps in the Japanese lighting market, 500 million will be replaced with LED lighting. Such a huge market has attracted the attention of global LED companies, and Chinese companies are doing their part. At Lighting Japan 2015, the number of Chinese exhibition areas has increased from three to four last year, and the number of companies has increased to 60.
“There are many viewers, but our booth is not in the interest.†Among the dozens of Chinese companies exhibiting, most of them have gained a lot, but there have also been dissatisfaction. Why is this happening?
Unlike the domestic market, the Japanese LED lighting market has entered a mature stage. As a country with relatively scarce energy sources, the nuclear accident in Fukushima, Japan, has exacerbated the seriousness of this problem. The government's subsidies and incentive policies, LED companies spare no effort to publicize, and the people's demand for electricity prices to increase electricity prices have really stimulated the explosive growth of alternative home lighting products such as bulbs and ceiling lamps. It seems that the growth of this market has slowed down and will reach saturation within two years. Sure enough, the reporter found that this exhibitor, which has few audiences, is exhibiting these alternative products that are saturated.
In contrast, Japanese exhibitors, starting with the characteristics and advantages of LED itself, set an example for the industry in two aspects. On the one hand, while digging deep into the potential of LED lighting technology, they are still working hard on product design. The organizer has specially developed an exhibition area for high-brightness technology, and high-power products for potential markets such as commercial lighting, office lighting and factory lighting have been sought after by buyers. Combined with new materials, all kinds of unique new style lamps not only reflect the designer's understanding of LED characteristics, but also earn a lot of attention.
On the other hand, they play the unique advantage of LED lighting and open up new application areas. In the lighting control exhibition area, buyers of intelligent lighting solutions are in constant stream. New products used in the agricultural sector and in the field of medical beauty have also attracted a large number of visitors.
We may wish to see the leading Japanese market as the epitome of the future global market. From the experience of the Japanese market, it took only two years for the penetration rate of LED lighting to increase from 20% to 50%. After that, if it is still limited to the replacement of traditional light sources, enterprises will have no room for further development. Therefore, domestic enterprises should change their thinking as soon as possible, step out of the horns of alternative design, and spend more thoughts on better playing the characteristics of LEDs.
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.
