How to hook up 2 solar panels together.

Connecting multiple solar panels. 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. There are 3 ways to connect solar panels.

Connecting in series means joining the positive terminal of a solar panel to the negative terminal of the next solar panel until eventually you are left with one free positive and one free negative terminal of the array which are to be connected to the input either of the inverter in case of a grid tied system without a battery backup or the charge controller in case of a grid tied system with a battery backup or off grid solar panel system. 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. Connecting two solar panels in parallel. The parallel connection allows to increase the current keeping the same voltage.

Parallel series and a combination of parallel and series. Connect the negatives to the negatives and positives to the positives. Theses are the diodes that i use they are the same ones that are used when building the panels. Then they are connected to the charge controller or to the inverter of the solar system.

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. If you had 4 solar panels in parallel and each was rated at 12 volts and 5 amps the entire array would be 12 volts at 20 amps. Nonetheless it is possible to wire them in parallel. Connect all the positive terminals of all the solar panels together and all the negative terminals of all the panels together.

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.
