When it comes to selecting solar photovoltaic (PV) modules, do you pay special attention to the voltage of the target model? Are you aware of how a small voltage parameter can impact the overall quality of a solar power station?

If you do, then you're undoubtedly a very cautious buyer. If you haven't paid attention before, don't worry. After reading this article, you won't overlook this crucial information in solar panel parameters again!

The voltage value of solar panels is one of the important factors to consider in the design and use of solar power systems. When selecting solar panels, it's often necessary to choose based on specific requirements and operating conditions.

Typically, the Working Voltage of solar panels varies within the range of rated voltage. The main factors affecting the actual Working Voltage of solar modules are as follows:


Temperature is the primary factor influencing the Working Voltage of solar panels. The voltage of PV modules changes with temperature; the higher the temperature, the lower the voltage.

Light Intensity:

Light intensity is another important factor affecting the Working Voltage of PV modules. The higher the light intensity, the higher the voltage, and vice versa.


The output voltage of solar panels is affected by circuit impedance; the lower the impedance, the higher the output voltage.

When connecting PV modules in series, it's necessary to use modules with the same rated voltage level and temperature coefficient to ensure stable operation of the system.
