Solar meter will see the weather market sales upstream

In summer, this is the best time for solar sales, but this year's sales are not very good. Surprisingly, in Lanzhou, due to the addition of certain types of solar meters, sales of solar energy have risen upside-down, achieving remarkable results.

It is reported that this section is favored by the majority of solar manufacturers and distributors of solar meters is a patented product developed by the Gold core electronics through ten years, is a solar industry rare invention patents. Compared with other instruments on the market, this product has greatly improved the technology. In the first few years, many companies and distributors did not attach great importance to the functions of the instrument. They thought that these functions were not effective and the price was higher, and there was no large-scale promotion. In recent years, with the fierce competition in the industry, companies and distributors have discovered that, in fact, solar water heaters do not have much room for technological improvement. Enterprises are playing with concepts and rely on strong advertising and vigorous promotional activities. As a result, companies began to pay attention to solar meters that look at the weather. Feedback from users of these companies is very good. Dealers also have new and distinctive selling points, and sales have quickly arrived. With the current industry continuing to be weak, solar meters that look at the weather have become a beautiful landscape.

It is understood that Goldman Sachs Electronics has cooperated with several companies such as Chongqing Op, Shaanxi Huayang, Rongshida, and Changsheng Solar. Solar-powered meters that look at the weather have become a powerful weapon for these companies to cope with the market. The selling point, product sales increased significantly.

Liu Shibin, general manager of Gold core electronic marketing, introduced that the reason why the solar energy meter will look different from the weather is because it has the following technical advantages. These advantages are unmatched by solar meters on the market.

One is the patented sensor technology that can be synchronized with the life of solar energy equipment.

At present, the electrode type sensors used in the market directly measure the water level with the resistance of water, and have multiple contact points with water. These contact points will not work properly when scale is present, especially in the northern regions until now. Life is still hard to do. The capacitive sensor used in this system is non-contact, and the technology itself requires isolation from water, so the scale problem will not only have an impact on it, but it can also provide better insulation protection. Because this kind of sensor can realize non-contact measurement, it is especially suitable for liquid level measurement of acids, alkalis, organic solvents, ammonia, crude oil, etc. It is widely used in metallurgy, petroleum, chemical industry and other industries. Gold core Electronics began to use this sensor technology in 2002. After more than two years of small-scale use verification, it applied for a patent in 2004. In 2009, it obtained a national invention patent technology certificate. The current technology application is very mature, and the lifespan of the sensor is also Basically it can be synchronized with solar energy equipment.

The second is that the water level can be divided into 100 levels to achieve linear and precise control.

The sensor is used as the sensory organ of the control system, and the measurement accuracy is its most important indicator. Every 1% increase is the last step or even the last step for the sensor. The greatest advantage of the capacitive sensor used in this system lies in its high resolution. It can divide the water level into 100 digits and displays the measurement accuracy better than the conventional instrument with only 4 levels of water level, making the control work linear and precise. Like 1%, 2% of the water control accuracy can be achieved, can make solar water heaters in the water level display, hot water production rate, auxiliary electric heating and other aspects to achieve the best state.

The third is to automatically look at the weather and produce hot water when there is insufficient sunshine.

Due to the instability of solar energy and the capacity of the storage tank, how to convert the limited sunlight into the same amount of hot water automatically is the biggest technical problem facing the industry and the key point for product upgrading and innovation. Because the sensor resolution of this system is very high, it can capture subtle changes in the water level. The computer then compares and analyzes it with the current water temperature and time. It can be easily judged whether it is day or night, whether it is a sunny day or a rainy day. There is no need for any artificial setting operation. The sun will automatically fill the water when the sun is good. When the sun is weak, it will automatically add less water. Even if there is more than half of the sun in the cold winter, the user can use the ideal heat. Water greatly reduces the unnecessary waste of electrical heating and reduces the operating costs of the water heater.

At the same time, the solar energy meters that look at the weather also have many advantages such as automatic power off, avoiding energized water for users, automatic memory of water supply, prevention of long running water, automatic emptying of pipelines, frost-free plugging, and hot water at the beginning.

In the past, due to the large number of instrument problems and the large amount of after-sales products, the use of meters was not advocated. Currently, the market penetration rate of instruments is less than 40%. It can be seen from this that there is considerable room for the development of highly technical solar meters. Every big solar instrument manufacturer wants to have a slice of glass, so it must be fully prepared.
