Solar panels (also called solar cell modules) are assembled by multiple solar cells, which are the core part of the solar power system and the most important part of the solar power system. Among the solar panels we usually produce, solar panels have test conditions and power calculations. So what are the test conditions and power calculations for solar panels? Let's take a look together next.
Here is the content list:
Since the output power of solar panels depends on factors such as solar irradiance and solar panel temperature, solar panels are measured under standard conditions (STC), which are defined as air quality AM1.5 and light intensity 1000W/m2, the temperature is 25°C. Under this condition, the maximum power of the solar panel output by the solar panel is called peak power. In many cases, the peak power of the solar panel is usually measured with a solar simulator. The main factors affecting the output performance of solar panels are as follows: load impedance, sunshine intensity, temperature, shadow.
The solar AC power generation system is composed of solar panels, charge controllers, inverters, and batteries. Solar DC power generation systems do not include inverters. To enable the solar power generation system to provide sufficient power for the load solar panels, it is necessary to select various components reasonably according to the power of the electrical appliances. Take the 100W output power and use it for 6 hours a day as an example to introduce the calculation method of solar panels.
First, calculate the number of watt-hours consumed per day (including the loss of the inverter): If the conversion efficiency of the inverter is 90% when the output power is 100W, the actual output power of the solar panel should be 100W/90 %=111W; if it is used for 5 hours a day, the power consumption of the solar panel is 111W*5 hours=555Wh.
Calculate the solar panel: According to the daily effective sunshine time of 6 hours, taking into account the charging efficiency and the loss during the charging process, the output power of the solar panel should be 555Wh/6h/70%=130W. Among them, 70% is the actual power used by the solar panel during the charging process.
