Solar panel application principle
Silicon is one of the most abundant elements on Earth. Since the discovery of its semiconductor properties in the 19th century, it has revolutionized technology and even shaped the way humans think. By the end of the 20th century, silicon had become an essential part of daily life. Among its many applications, crystalline silicon solar cells have seen the fastest industrial growth in the past 15 years. The manufacturing process typically involves five main stages: purification, crystal pulling, slicing, cell fabrication, and packaging.
Understanding Solar Cell Applications:
Key Factors for Solar Panel Installation:
Question 1: In which areas is the solar power system used, and what is the level of solar radiation in that region?
Question 2: What is the total power consumption of the system?
Question 3: What is the output voltage of the system—direct current (DC) or alternating current (AC)?
Question 4: How many hours per day does the system need to operate?
Question 5: How many consecutive days can the system operate during rainy weather without sunlight?
Question 6: What type of load is being used—resistive, capacitive, or inductive—and what is the starting current?
Question 7: How many systems are required for the project?
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 impact overall performance. Therefore, it's important to follow established standards when using solar panels.
2. The ideal installation angle for solar panels usually faces south, meaning the panel should be positioned so that it is directly facing the sun. However, this angle varies depending on the latitude of the location.
3. While some regions may receive over 8 hours of sunlight per day, the effective power generation time is typically between 4 to 6 hours. This data can vary and should be checked with local resources.
4. Solar panel performance is measured under standard test conditions (AM1.5, 1000 W/m², 25°C). Real-world conditions often differ, leading to variations in actual performance.
5. Solar energy generation is not constant—it follows a curve throughout the day, with lower output in the morning and evening, and higher output in the afternoon. Based on this, users should pay attention to factors like light intensity, ambient temperature, installation angle, and power generation duration to maximize efficiency.
