Open circuit 20.88V voltage is the voltage that comes directly from the 36-cell solar panel. When we are asking how many volts do solar panels produce, we usually have this voltage in mind. For maximum power voltage (Vmp), you can read a good explanation of what it is on the PV Education website.
Let’s break it down in simple terms. Voltage is the push behind the electricity that flows through your solar panels. Speaking of panels, every solar panel has a certain voltage output. Keep in mind that this output might vary based on factors like sunlight, temperature, and the number of solar cells in the panel.
The solar panel voltage output comes from the photovoltaic effect. This is when sunlight hits certain materials, like silicon, in the solar cells. These solar cells are part of a solar panel. These materials can make an electric current with light, called the photovoltaic effect. Sunlight, or photons, shines on the solar cells.
As we can see, solar panels produce a significantly higher voltage (VOC) than the nominal voltage. The actually solar panel output voltage also changes with the sunlight the solar panels are exposed to.
Voltage output directly from solar panels can be significantly higher than the voltage from the controller to the battery. Maximum Power Voltage (Vmp). The is the voltage when the solar panel produces its maximum power output; we have the maximum power voltage and current here. Here is the setup of a solar panel:
It shows your solar panel’s rated voltage output. Common values are 12V, 18V, 20V, or 24V. Keep in mind that the collective voltage of an array changes depending on the setup. When going solar, consider these three types of voltages. They will help you make an informed decision. You may have noticed that solar panels come with an efficiency rating.
