Difference Between Series And Parallel Connection Of Solar Panels

Unlike connecting in series connecting in parallel allows the voltage to stay the same but the current adds up.

Difference between series and parallel connection of solar panels.

Series vs parallel wiring of solar panels similar to batteries solar panels also come with a positive and negative terminal. Consider having a set of four solar panels. Parallel wiring is when the positives of multiple modules are connected together and all the negatives for the same modules are connected together. A series wired circuit will use a single wire to connect.

For example you can wire two sets of four 100 watt solar panels in series then wire those two sets in parallel to create an 800 watt array. Here are the fundamental differences between wiring solar panels in series vs. 4 panels in series needs to be parallel with another 4 panels in series or there will be some serious power loss. 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.

Wiring solar panels in series when a solar installer wires your solar panels in a series each panel is connected to the next in a string the total voltage of each solar panel is summed together but the amps of electrical current stay the same. With the help of these terminals you can connect the solar panels in the desired fashion. Then an equal string needs to be created and paralleled. Solar cells can also be arranged in parallel where each solar panel is connected to every other panel in the circuit.

Parallel wiring increases the current amps output of a solar array while keeping the voltage the same. When you do a series parallel connection on your solar system you need to parallel two or more equal sized series strings together. Here is an example of what is found in most. There isn t really a downside to series parallel connections.

Meanwhile a parallel wired system will have multiple wires to connect it into the grid. Three panels of 12v and 3a and one panel of 9v and 1a. 4 panels in series needs to be parallel with another 4 panels in series or there will be some serious power loss. You can see more in the example below.

Then an equal string needs to be created and paralleled. In fact it s the exact opposite of connecting in series. For this connection a string is created by 2 or more panels in series. So let s start with the series wiring of a solar panel system as it is less complicated than the parallel wiring.

Remember the intrinsic characteristics of each type of connection the parallel connection forces all the system to have the same voltage and the series connection forces all the system to have the same current. There isn t really a downside to series parallel connections.
