How To Connect Solar Panels Together

They can be wired in parallel.

How to connect solar panels together.

By connecting multiple solar panels in series we increase the system voltage. Solar panels are usually connected in series to obtain higher output voltage. 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.

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. 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. 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.

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. Both have their own purpose and applications and both have different outcomes when hooking up solar panels of different wattage together. After these clarifications let s see how the series connection takes place.

There are two ways to wire up solar panels. So if you connect two solar panels with a rated voltage of 40 volts and a rated amperage of 5 amps in series the voltage of the series would be 80 volts while the amperage would remain at 5 amps. Firstly lets take a look at connecting solar panels in series. Just check a few things first.

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. 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. You too can connect two solar panels into one system just like we do.
