How To Connect Different Solar Panels Together

Series connection of two solar panels with different current 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.

How to connect different solar panels together.

Nonetheless it is possible to wire them in parallel. Then they are connected to the charge controller or to the inverter of the solar system. Connecting solar panels in parallel is just the opposite of series connection and is used to increase the total output current of the array and hence the total output power while keeping the same voltage. For this example i am showing you connecting panels that are for a 12 volt system.

Total power 150w 150w 150w 150w 600w. But at night the solar panel looks like a resistor and will slightly discharge the battery. This is usually the case with 24v systems. There are 3 ways to connect solar panels.

If both panels are rated at the same maximum voltage then you ll get maximum output. Connecting two solar panels in parallel. If we have two solar panels with same voltage and power the connection will be very simple. To power a dual battery system you ll need to connect the panels in parallel.

As clearly visible in the picture it will be enough to wire the positive pole of one panel to the positive pole of the other one and then wire the negative pole of one panel to the negative pole of the other 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. If we connect 4 x 150w solar panels in series the total power is calculated as follows. Connect the negatives to the negatives and positives to the positives.

So they usually put a diode between the panel and the battery. Completely discharging it over time. If you just connect a solar panel to a battery when there is light the battery charges. Parallel series and a combination of parallel and series.

Connecting solar panels in parallel wiring solar panels in parallel implies connecting positive terminals of each panel together and wiring the negative terminals of each panel together as well.
