The amps of electrical current for each solar panel are summed together but the system voltage stays the same.
Caravan solar panels series or parallel.
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.
Solar panels are connected in parallel to obtain higher output current.
2 panels or more can be connected in parallel positive to positive resulting in the same voltage but double the watts.
The positive wires are connected to a positive connector within a combiner box and the negative wires are connected to the negative connector.
The same voltage is the system voltage which for off grid solar panels systems is usually as low as either 6v or 12v.
When solar panels are wired in parallel 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.
Now lets look at connecting solar panels in parallel.
Wiring your solar panels in parallel increases the amperage while keeping the voltage the same.
In fact it s the exact opposite of connecting in series.
For series at the 57 volts and 9 amps we can use 10 gauge wire for anything under 70 feet from the panels to the charge controller.
Solar cells can also be arranged in parallel where each solar panel is connected to every other panel in the circuit.
Unlike connecting in series connecting in parallel allows the voltage to stay the same but the current adds up.
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.
This can be done with the usual mc 4 solar panel connectors.
Also 2 or more batteries can be connected together in parallel to double the storage capacity.
In parallel we can use 10 gauge wire from the solar panelsto the combiner box but only if the longest wire length is shorter than 24 feet.
This is usually used with 12v set ups.
Wiring in series is done by joining the positive wire of one solar panel to the negative wire of another panel.
