How To Connect Multiple Solar Panels Together

Connecting two solar panels in parallel.

How to connect multiple solar panels together. Parallel series and a combination of parallel and series. 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. The series connection is done by wiring the positive terminal of each panel to the negative terminal of the next panel a connection similar to the ones of the christmas lights until the final panel is connected to the charge controller or inverter.

Maximum rated current 5 8a. You connect solar panels in series when you want to get a higher voltage. Considering the example in the figure two 5a 12v panels wired in series produce a voltage of 24v and a current of 5a. Connect the negatives to the negatives and positives to the positives.

Maximum rated voltage 19 8v. The connection of multiple solar panels in parallel arises from the need to reach certain current values at the output without changing the voltage. Wiring solar panels in a parallel circuit connect all the positive terminals of all the solar panels together and all the negative terminals of all the panels together. If both panels are rated at the same maximum voltage then you ll get maximum output.

There are two main types of connecting solar panels in series or in parallel. The type of your solar panels system the solar power you want to generate the other system components such as a charge controller battery and inverter. Connecting solar panels in series. For example our 115w sunpower solar blanket has the following ratings.
