Connecting 2 Solar Panels Together

The wedgetail camper has two solar inputs via red anderson plugs.

Connecting 2 solar panels together.

Both have their own purpose and applications and both have different outcomes when hooking up solar panels of different wattage together. Then they are connected to the charge controller or to the inverter of the solar system. I spoke to the people at wedgetail campers about how the two solar inputs were wired. How to connect two solar panels to one battery it s all in the wiring.

Connecting solar panels in parallel. Wiring solar panels in parallel implies connecting positive terminals of each panel together and wiring the negative terminals of each panel together as well. For this example i am showing you connecting panels that are for a 12 volt system. By connecting multiple solar panels in series we increase the system voltage.

As clearly visible in the picture it will be enough to wire the positive pole of one panel to the positive pole of the other one and then wire the negative pole of one panel to the negative pole of the other one. The first way i am going to talk about is parallel because this is probably the most common way that panels will be connected. 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. The same voltage is the system voltage which for off grid solar panels systems is usually as low as either 6v or 12v.

The first is on the roof. In a solar power system the higher the voltage and the lower the energy losses along the cables to know the maximum system voltage we usually just need to turn the panel and read the label where the value is reported. There are 3 ways to connect solar panels. Parallel series and a combination of parallel and series.

The positive wires are connected to a positive connector within a combiner box and the negative wires are connected to the negative connector. There are two ways to wire up solar panels. 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. Wiring solar panels in a parallel circuit connect all the positive terminals of all the solar panels together and all the negative terminals of all the panels together.

Solar panels are usually connected in series to obtain higher output voltage.
