How To Connect 2 Solar Panels Together

Wiring solar panels in a parallel circuit.

How to connect 2 solar panels together.

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. The wedgetail camper has two solar inputs via red anderson plugs. 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.

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. After these clarifications let s see how the series connection takes place. It s all in the wiring. Connect all the positive terminals of all the solar panels together and all the negative terminals of all the panels together.

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. This is used when the solar panel is stored for travelling. When solar panels are wired in series the voltage of the panels adds together but the amperage remains the same. If we have two solar panels with the same voltage but different wattage there is no problem.

When the wedgie is open the roof hinges over 180 degrees and becomes the base of our bed. 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. 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.
