How To Hook Up Multiple Solar Panels

4 panels in series needs to be parallel with another 4 panels in series or there will be some serious power loss.

How to hook up multiple solar panels.

For this connection a string is created by 2 or more panels in series. One positive and one negative. There are 3 ways to connect solar panels. The parallel connection allows to increase the current keeping the same voltage.

For this example i am showing you connecting panels that are for a 12 volt system. Parallel series and a combination of parallel and series. Nonetheless it is possible to wire them in parallel. Then an equal string needs to be created and paralleled.

For more information visit the page how to wire solar panels in parallel. Just like a battery solar panels have two terminals. If we have two or more solar panels with the same voltage but with different current it is not possible to wire them in series. To wire two or more solar panels and batteries in parallel simply connect the positive terminal of solar panel or battery to the positive terminal of solar panel or battery and vise versa respectively as shown in the fig below.

When you connect two or more solar panels like this it becomes a pv source circuit. You want to make sure you get a charge controller that is big enough to regulate the total volume of solar panels you ve had installed on your house. When you connect the positive terminal of one panel to the negative terminal of another panel you create a series connection. You can see more in the example below.

Wiring solar panels in a series circuit connect the positive terminal of the first solar panel to the negative terminal of the next one.
