"Silicon" is one of the most abundant materials on our planet. Since the discovery of the semiconductor properties of crystalline silicon in the 19th century, it has changed almost everything, even human thinking. At the end of the 20th century, the role and role of â€œsiliconâ€ can be seen everywhere in our lives. Crystalline silicon solar cells have become the fastest industrialized in the past 15 years. The production process can be roughly divided into five steps: a, purification process b, draw bar process c, slicing process d, battery process e, and packaging process.
Solar cell applications:
Solar panel factors
Question 1. Where is the solar power system used and how is the solar radiation in the area?
Question 2. How much load power does the system have?
Question 3. What is the output voltage of the system, DC or AC?
Question 4: How many hours does the system need to work every day?
Question 5: How many days does the system need to be powered continuously in the event of rainy weather without sunlight?
Question 6, the load situation, purely resistive, capacitive or inductive, how much starting current?
Question 7, the number of system requirements?
For example: 1. The power generation capacity of solar cells is closely related to light intensity, ambient temperature, and installation angle. Changes in each link will affect the power generation of the panel. Therefore, in the process of using solar panels, the corresponding standards should be met! 2. The installation/placement angle of solar cells generally faces the south (ie, the angle between the vertical plane of the solar panel and the south is 0). . The latitude varies from place to place, and the angle of inclination is also different. 3. The sunshine time is different from the effective power generation time of solar energy. There are more than 8 hours of sunshine in the general area of â€‹â€‹China, but the effective power generation time is usually about 4-6 hours. Specific data can be queried for professional information. 4. The electrical performance parameters of solar panels are tested under internationally accepted standard conditions (AM1.5, 1000W/square meter, 25 degrees). Because the actual use environment is different, the measured data will always be more or less. The difference. 5, solar power generation is constantly changing, is a curve process, generally less power generation in the morning and evening, more power generation in the afternoon. Xiaobian concluded that in the process of using solar panels, attention should be paid to: light intensity, ambient temperature, installation angle, sunshine time, power generation time limit, etc.
R507 is an HFC blend designed to be a replacement for R502 in low and medium temperature refrigeration applications. It is similar in characteristics to R404A however, being an azeotropic blend, R507A does not suffer from glide or fractionation making it suitable for additional applications such as centrifugal compressors.
