How To Connect 2 Solar Panels Together

When solar panels are wired in series the voltage of the panels adds together but the amperage remains the same.

How to connect 2 solar panels together.

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. 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. By connecting multiple solar panels in series we increase the system voltage. This is used when the solar panel is stored for travelling.

Wiring solar panels in a parallel circuit. 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. If we have two solar panels with the same voltage but different wattage there is no problem. The first is on the roof.

After these clarifications let s see how the series connection takes place. In a solar power system the higher the voltage and the lower the energy losses along the cables to know the maximum system voltage we usually just need to turn the panel and read the label where the value is reported. It s all in the wiring. 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 wedgetail camper has two solar inputs via red anderson plugs. They can be wired in parallel. Connect all the positive terminals of all the solar panels together and all the negative terminals of all the panels together.
