How To Connect Solar Panels Together

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.

How to connect solar panels together.

Solar panels are usually connected in series to obtain higher output voltage. 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. Connecting solar panels in series. Just check a few things first.

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. By connecting multiple solar panels in series we increase the system voltage. 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. If we have two solar panels with the same voltage but different wattage there is no problem.

Are the solar panels compatible. Redarc sell a ready made cordset with grey anderson plugs. You too can connect two solar panels into one system just like we do. After these clarifications let s see how the series connection takes place.

Firstly lets take a look at connecting solar panels in series. When solar panels are wired in series the voltage of the panels adds together but the amperage remains the same. 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. They can be wired in parallel.

The best way to find out is to contact your solar panel supplier. It allows you to connect two panels then connect them into one solar input. The series connection is done by wiring the positive terminal of each panel to the negative terminal of the next panel a connection similar to the ones of the christmas lights until the final panel is connected to the charge controller or inverter.
