So when connecting solar panels in series always try to keep the electrical properties of the solar panels identical to get the full benefit of the solar array.
Connecting solar panels of different voltage in parallel.
This is usually used with 12v set ups.
Unlike connecting in series connecting in parallel allows the voltage to stay the same but the current adds up.
Wiring solar panels in parallel causes the amperage to increase but the voltage remains the same.
This will prevent reverse voltage damage so that the higher voltage panel will not destroy the lower voltage panel.
But first you need to connect rectifier diode on each output.
It has anode and cathode the one marked with single line.
They can be wired in parallel.
In fact it s the exact opposite of connecting in series.
Contrary to the combination in series when solar panels are connected in parallel there may be one panel having power output below the spec of the other devices this could perhaps not influence the total power output of the chain significantly only if this particular panel possesses voltage rating on par with the other modules voltage.
The capacity of a solar panel to produce energy is measured in watts which is calculated by multiplying a solar panel s voltage by the amps of current it produces when a solar installer builds a solar energy system they need to find the right balance of voltage and amps to ensure that the system performs well.
Solar cells can also be arranged in parallel where each solar panel is connected to every other panel in the circuit.
If you connect these four panels in parallel all of them must have the same voltage and therefore will generate at the maximum possible voltage for one of the panels which means 9v.
Rectifier diode will connect in forward bias.

If you want to connect.
With parallel solar panels the positive terminal from one panel is connected to the positive terminal of another panel and the negative terminals of the two panels are connected together.
Comparing solar panels in series vs.
Now lets look at connecting solar panels in parallel.
Solar panels are connected in parallel to obtain higher output current.
If we have two solar panels with the same voltage but different wattage there is no problem.
