How To Hook Up Multiple Solar Panels

When you connect two or more solar panels like this it becomes a pv source circuit.

How to hook up multiple solar panels.

For this connection a string is created by 2 or more panels in series. 4 panels in series needs to be parallel with another 4 panels in series or there will be some serious power loss. For this example i am showing you connecting panels that are for a 12 volt system. In general you simply have to obtain a charge controller that is able to handle the number of solar panels you have on your home.

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. One positive and one negative. You can see more in the example below. For more information visit the page how to wire solar panels in parallel.

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. 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. The parallel connection allows to increase the current keeping the same voltage. Wiring solar panels in a series circuit connect the positive terminal of the first solar panel to the negative terminal of the next 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. Nonetheless it is possible to wire them in parallel. There are 3 ways to connect solar panels. Parallel series and a combination of parallel and series.

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.
