Connecting 4 Solar Panels In Series

When you connect two or more solar panels like this it becomes a pv source circuit.

Connecting 4 solar panels in series.

Then an equal string needs to be created and paralleled. Solar panels are usually connected in series to obtain higher output voltage. 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. When you wire in series there is just a single wire leading from the roof for each string of solar panels.

When solar panels are wired in series the voltage of the panels adds together but the amperage remains the same. When a solar installer wires your solar panels in a series each panel is connected to the next in a string the total voltage of each solar panel is summed together but the amps of electrical current stay the same. Having said that when panels are attached in series one of the panel may carry a rated power below the other panel because of the lower current spec of this solar panel with respect to the other modules in the chain that unit could tend to. You can see more in the example below.

After these clarifications let s see how the series connection takes place. If we connect 4 x 150w solar panels in series the total power is calculated as follows. For example if you installed 5 solar panels in series with each solar panel rated at 12 volts and 5 amps you d still have 5 amps but a full 60 volts. In the below solar series wiring diagram i shown 4 solar panels which is 12 volts and 8 amperes when we connect these panel in series with one another the complete output of our panel come 48 volts and 8 amperes.

Absolute interconnected power 150w 150w 150w 150w 600w. Connecting solar panels in series. For this connection a string is created by 2 or more panels in series. Firstly lets take a look at connecting solar panels in series.

By connecting multiple solar panels in series we increase the system voltage. If you are connecting two 100 watt panels in series and each panel has an output of 18 9 volts you will end up with 200w 37 8 volts and 5 29 amps under optimum conditions. Wiring solar panels in series. 4 panels in series needs to be parallel with another 4 panels in series or there will be some serious power loss.

This is usually the case with 24v systems. When installing solar panels in series the voltage adds up but the current stays the same for all of the elements. Connecting solar panels in series 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.
