The practical value of flat panel solar energy

AUTHOR:adminFROM:本站RELEASE:2024-4-8 21:35:50

Flat panel solar energy typically uses specially tempered glass containers, with a receiving capacity of around 2000 kilograms. Its static load is sufficient to withstand a free fall impact of 6 kilograms of iron balls, and it has high strength and good operational performance.

Exclusive overheating maintenance function, usually when the temperature reaches 70 degrees, the system can actively suppress the temperature increase, and then ensure that the system is safe and reliable. Furthermore, it has anti freezing function and can be used normally at minus 20 degrees Celsius in winter, with the advantage of melting ice and snow. Very good overcoming the phenomenon of solar energy hibernation.

After decades of development, flat panel solar water heaters have become more mature and sophisticated in skills, and have advantages and characteristics that other types of solar energy do not have. One is particularly suitable for the integration of construction needs. Flat panel solar water heaters, due to their planar structural characteristics, have a flexible and arbitrary shape and structure in the integrated application of solar energy construction. They are not bound by shape or scale during design and are easy to connect with building components. In addition, its collector plate is made of metal raw materials, which can be easily connected using methods such as wire bonding and welding, providing convenience for installation, maintenance, and application. Secondly, it has a high thermal power. Because the vacuum tube solar collector is composed of several vacuum tubes, there are gaps between the tubes, and when illuminated by sunlight, a portion of the solar energy is not received by the collector. A flat solar collector is a continuous plane, and the entire surface of the collector can receive sunlight. So, under the same lighting area and sunshine intensity, the daily uniform power of flat panel solar water heaters is usually more than 6% higher than that of vacuum tube solar water heaters. Thirdly, it has good pressure resistance function. Because the heat absorbing plate of the flat panel solar collector is made of metal materials, and the connection between the collector and the water storage tank is also made of metal parts, it can accept pressure from tap water and circulating pumps. Urban water use usually adopts a centralized water supply system, with high tap water pressure, which requires a certain pressure of hot water from solar water heaters. Then, the pressure difference between the water heater outlet and the tap water outlet is reduced to provide convenient and comfortable use for users. Fourthly, the function is stable when forming a large system. For some large venues, such as hotels, swimming pools, factories, etc., when using solar water heaters, many solar collectors are usually required to form a large-scale water supply system. If a flat panel solar collector is selected and connected with metal between the collector and the system, instead of rubber parts like vacuum tube solar water heaters, it can ensure the stability of the entire system. Therefore, when establishing a large-scale solar hot water system, flat panel solar collectors are usually used. In addition, due to its simple structure, convenient processing, and ease of large-scale production, the flat panel solar water heater also has the characteristics of low production cost, low installation cost, and long service life. Of course, the high heat loss and anti freezing issues of flat panel solar collectors also need to be further resolved through technological innovation. In order to actively participate in international competition and open up high-end domestic shopping malls, it is necessary for us to attach importance to the research and development of flat panel solar water heaters, and with a more open attitude, improve the skill level and internationalization level of China's solar thermal use.
