Explanation of common values of solar panel output voltage

I. Output characteristics of solar panels

Solar panels are devices that convert solar radiation into electricity, and their output characteristics are related to solar irradiance and panel temperature. When the intensity of solar radiation increases, the output voltage of the solar panel increases; when the plate temperature increases, the output voltage of the solar panel decreases. Therefore, the output characteristics of the solar panel is a non-linear function, the output voltage value will also fluctuate.

Second, the solar panel output voltage range

The output voltage of a solar panel is DC, and its typical values are 12V, 24V, 36V, 48V, etc. The output voltage of a solar panel is DC. The output voltage of different types of solar panels varies, and at the same time, the output voltage of the same type of solar panels will also have a certain fluctuating range. The following are the ranges of common solar panel output voltages:

1. 12V solar panel output voltage range is 10V-17.5V;

2. 24V solar panel output voltage range is 20V-35V;

3. 36V solar panel output voltage range is 30V-45V;

4. 48V solar panel output voltage range is 40V-60V.

It is important to note that these values are approximate ranges and the actual values will fluctuate. The actual value of the solar panel output voltage is also affected by the load. When the load current increases, the output voltage of the solar panel will decrease.

Ⅲ.the application of solar panel output voltage

The output voltage of solar panels can be used to power DC devices such as batteries, lamps, automobiles, boats, and so on. These devices require operating voltages within the output voltage range of the solar panel.

Additionally, the solar panel output voltage can be used for charge control. A typical solar cell charge controller monitors the output voltage and current of the solar panel and converts the electrical energy into a power source that can charge the battery. By reasonably configuring the solar panel output voltage and the battery charge controller, solar energy can be effectively utilised for power storage.

Conclusion

The output voltage of the solar panel is an important technical indicator, and its range and fluctuation will directly affect the power output and use efficiency of the solar panel. By understanding the characteristics and application range of solar panel output voltage, it can better provide a reference basis for the design and application of solar power system.
