How do you connect 2 solar panels together.

Connecting multiple solar panels in parallel refers to 2 or more solar panels of the same wattage being connected positive to positive negative to negative. There are two ways to wire up solar panels. Parallel series and a combination of parallel and series. When solar panels are wired in series the voltage of the panels adds together but the amperage remains the same.

Solar panels are usually connected in series to obtain higher output voltage. For this example i am showing you connecting panels that are for a 12 volt system. Firstly lets take a look at connecting solar panels in series. There are 3 ways to connect solar panels.

They can be wired in parallel. When using two panels of the same voltage and amperage rating remains unchanged. When wiring two panels in series the voltage and wattage double. If we have two solar panels with the same voltage but different wattage there is no problem.

You have two different higher voltage solar panels i e one 100w 24v and one 200w 24v that you want to connect to the already working 12 v solar power system comprising the two 12v 50 w solar panels connected in parallel from the previous scenario see the picture above. On the other hand if our two solar panels have both different wattage and different voltage then parallel connection is not possible since the panel with the lowest voltage would behave like a load and would begin to absorb current instead of producing it with the.

Three panels of 12v and 3a and one panel of 9v and 1a. If you connect these four panels in parallel all of them must have the same voltage and therefore will generate at the maximum possible voltage for one of the panels which means 9v. Solar panels are wired in series when you connect the positive terminal of one panel to the negative terminal of another. It allows you to connect two panels then connect them into one solar input.

The first way i am going to talk about is parallel because this is probably the most common way that panels will be connected.
