Connecting 2 Solar Panels Together

By connecting multiple solar panels in series we increase the system voltage.

Connecting 2 solar panels together.

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 3 ways to connect solar panels. After these clarifications let s see how the series connection takes place. 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.

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. 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. 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.

The wedgetail camper has two solar inputs via red anderson plugs. I spoke to the people at wedgetail campers about how the two solar inputs were wired. For this example i am showing you connecting panels that are for a 12 volt system. The first way i am going to talk about is parallel because this is probably the most common way that panels will be connected.

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. 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. Parallel series and a combination of parallel and series.
