It is possible to connect 2 solar panels of different voltage output in parallel.
Solar panels in parallel different voltages. If you want to connect diode on positive of your panel choose the anode of your diode. Such a reduction in voltage will lead to a reduction in power output and therefore loss in system performance. Connecting solar panels in parallel is just the opposite of series connection and is used to increase the total output current of the array and hence the total output power while keeping the same voltage. The same voltage is the system voltage which for off grid solar panels systems is usually as low as either 6v or 12v.
Similarly only solar panels of exact or similar voltage should be wired together in parallel. Connecting panels in parallel requires heavier wire to handle the higher current 25 amps vs 5 amps in the examples above and you need more wire to make all the connections to the different panels. Rectifier diode will connect in forward bias. But first you need to connect rectifier diode on each output.
The other would be at 372 6 v. Mostly the higher voltage panel will deliver most of the current and the low voltage panel does little. Many modules followed with 48 to 60 cells that produced voltages that were not a direct match for 12 or 24 volt nominal system components. On the other hand if our two solar panels have both different wattage and different voltage then parallel connection is not possible since the panel with the lowest voltage would behave like a load and would begin to absorb current instead of producing it with the relative consequences.
If the two panels have similar current ratings but different voltage rating you can put them in series to get the sum of the voltages at the single current rating. One string the string with 2 shaded panels before connecting in parallel with the other would be at 372 6 28 66 28 66 315 3 v. Using our same example of 5 panels each rated at 12 volts and 5 amps if you connected them in parallel you d still have 12 volts but now 25 amps. The modules acquired this name because their cell count and functional voltage ratings put them right in between the two existing categories of 12v and 24v nominal pv modules.
It has anode and cathode the one marked with single line. They can be wired in parallel. Wiring solar panels in parallel causes the amperage to increase but the voltage remains the same. Putting the two dissimilar panes in parallel is not a good idea.
So if you wired the same panels from before in parallel the voltage of the system would remain at 40 volts but the amperage would increase to 10 amps. When you connect a 15v panel to a 24 v panel the overall voltage will be dragged down to 15 volts.
