Solar panel application principle
Silicon is one of the most abundant elements on Earth, and its impact on modern life has been profound. Since the discovery of silicon’s semiconductor properties in the 19th century, it has revolutionized technology, shaping everything from computing to communication. By the late 20th century, silicon had become an essential part of daily life, especially with the rise of solar energy. Crystalline silicon solar cells have seen rapid industrial development over the past 15 years. The production process typically involves five main stages: purification, crystal pulling, slicing, cell fabrication, and packaging.

Key Factors for Solar Panel Installation:
Question 1: Where will the solar power system be used, and what is the level of solar radiation in that area?
Question 2: What is the total power consumption of the load that the system needs to support?
Question 3: What is the output voltage of the system, and is it DC or AC?
Question 4: How many hours per day does the system need to operate?
Question 5: How many consecutive days can the system operate without sunlight, such as during rainy weather?
Question 6: What type of load is being used—resistive, capacitive, or inductive—and what is the starting current?
Question 7: What are the specific system requirements?
For example: 1. The power generation capacity of solar panels is closely related to light intensity, temperature, and installation angle. Any changes in these factors can significantly affect performance. Therefore, it's important to follow proper guidelines when using solar panels. 2. The ideal installation angle for solar panels usually faces south, meaning the panel should be aligned directly with the sun. However, this angle varies depending on the latitude of the location. 3. While there may be more than 8 hours of sunlight in some areas of China, the actual effective power generation time is typically around 4–6 hours. This data can vary and should be verified with local experts. 4. The electrical performance of solar panels is tested under standard conditions (AM1.5, 1000W/m², 25°C). In real-world conditions, the output may differ due to environmental variations. 5. Solar power generation is not constant—it follows a curve, with lower output in the morning and evening and higher output in the afternoon. In summary, when using solar panels, it's crucial to consider factors like light intensity, ambient temperature, installation angle, sunlight duration, and power generation timing. Keeping these in mind ensures optimal performance and long-term efficiency.
