With solar panels, we can charge batteries, and batteries usually have 12V, 24V, or 48V input and output voltage. It is the job of the charge controller to produce a 12V DC current that charges the battery. Open circuit 20.88V voltage is the voltage that comes directly from the 36-cell solar panel.
Many modern MPPT controllers accept a wide voltage range (e.g., 12–60V input) and can automatically optimize for maximum power output. Even though solar panels can output 18–44 volts, most batteries charge at 12.8V–29V. To prevent overcharging and damage, you need a voltage regulator or charge controller. Simpler, lower cost.
Simply put, voltage is the measure of the electrical potential difference between two points. In the case of a solar panel, voltage refers to the amount of electrical potential that can be generated by the panel when exposed to sunlight. Voltage of a Single Solar Panel
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:
