How Do You Connect Two Solar Panels Together

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.

How do you connect two solar panels together.

Connecting two solar panels in parallel. Connect the negatives to the negatives and positives to the positives. When wiring two panels in series the voltage and wattage double. There are two main types of connecting solar panels in series or in parallel.

The first way i am going to talk about is parallel because this is probably the most common way that panels will be connected. There are 3 ways to connect solar panels. Parallel series and a combination of parallel and series. Wiring solar panels in parallel implies connecting positive terminals of each panel together and wiring the negative terminals of each panel together as well.

If both panels are rated at the same maximum voltage then you ll get maximum output. As clearly visible in the picture it is sufficient to wire the positive pole of one panel to the negative pole of the other and at the output we will find a doubling of the voltage. If you are wanting a series connection instead simply connect the positive lead on your solar panel to the negative on your solar panel and the negative lead to the positive on your second solar panel. Considering the example in the figure two 5a 12v panels wired in series produce a voltage of 24v and a current of 5a.

Connecting solar panels in parallel. You connect solar panels in series when you want to get a higher voltage. How to wire solar panels in parallel place the panels close to each other and oriented to the sun at the same angle check that the panels do not shade each other and that they are far from possible causes of shading choose an appropriate section of the electrical cable according to the. Maximum rated voltage 19 8v.

For example our 115w sunpower solar blanket has the following ratings. The positive wires are connected to a positive connector within a combiner box and the negative wires are connected to the negative connector. Then they are connected to the charge controller or to the inverter of the solar system.
