Understanding wattage is essential for determining how much energy a solar panel can produce and, consequently, how much power your devices or appliances can draw from it. For example, a solar panel with a voltage of 20V and an amperage of 5A has a wattage of 100W. This means the panel can produce 100 watts of power under optimal conditions.
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.
For example, let's say you have 4 identical solar panels, all with a voltage of 12 volts and a current of 8 amps. First, you wire 2 sets of 2 panels in series to create 2 series strings of 24 volts (12V + 12V) and 8 amps. Then, you wire both series strings in parallel to create a 4-panel array of 24 volts and 16 amps (8A + 8A).
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.
If you know the number of PV cells in a solar panel, you can, by using 0.58V per PV cell voltage, calculate the total solar panel output voltage for a 36-cell panel, for example. You only need to sum up all the voltages of the individual photovoltaic cells (since they are wired in series, instead of wires in parallel). Here is this calculation:
