Connect 2 Portable Solar Panels Together

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.

Connect 2 portable solar panels together. The idea is to establish strings series connection of two or more panels and connect them in parallel with other strings creating arrays of strings. 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.

The rule of thumb when connecting solar panels directly to a battery is never connect more than c 10 watts where c is the capacity of your battery. That is a parallel connection. For example a 110ah battery should never be connected to a panel more than 11w without a solar controller and if you are using a solar controller you do not need a blocking diode. The nominal voltage remains at 12v.

Maximum rated voltage 19 8v. For example our 115w sunpower solar blanket has the following ratings. Maximum rated current 5 8a. 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.

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.
