Three primary terms commonly used to describe solar panel voltage characteristics are Voc (open-circuit voltage), Vmp (voltage at maximum power), and Imp (current at maximum power). Voc represents the maximum voltage output of a solar panel when no load is connected, i.e., under open-circuit conditions.
A solar panel with no load isn’t connected to any devices. When not connected to a device, a solar panel will still absorb sunlight but won’t have anywhere for the energy to go. It has voltage, but no current is flowing. Because the voltage has nowhere to go, it will become heat in the solar cells and radiate from the panel until it dissipates.
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. When we are asking how many volts do solar panels produce, we usually have this voltage in mind.
This is the actual voltage of the circuit once a load (an appliance like a heater, phone charger, etc.) is connected to it. AC Volts is the voltage after an inverter has converted DC Volts to AC Volts. In various articles, solar panel output voltage refers to either nominal voltage, the open-circuit voltage at maximum power, or actual voltage.
Nominal voltage is an approximate solar panel voltage that can help you match equipment. The voltage is usually based on the nominal voltages of appliances connected to the solar panel, including but not limited to inverters, batteries, charge controllers, loads, and other solar panels.
A solar PV system that isn’t collected to a load will remain in an open circuit condition. That’s another saying that it will absorb the sun but have nowhere to send the power. As discussed above, this is fine for short periods but can cause damage if done continuously. Can Solar Panels Charge With Indirect Sunlight?
