Connecting 2 Solar Panels In Series

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

Connecting 2 solar panels in series.

Solar panels are usually connected in series to obtain higher output voltage. 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. In a solar power system the higher the voltage and the lower the energy losses along the cables. If we connect 4 x 150w solar panels in series the total power is calculated as follows.

The connecting solar panels in series is very easy just like connecting battery cell with one anther however lets get a review on this. If you however need to get higher current you should connect your panels in parallel. There are two main types of connecting solar panels in series or in parallel. What does it mean to wire solar panels in series.

By connecting multiple solar panels in series we increase the system voltage. Just like a battery solar panels have two terminals. Total power 150w 150w 150w 150w 600w. If we have two or more solar panels with equal current and power and we want to increase the voltage the choice falls on the series connection.

At this point any specific difference in voltages is not crucial voltages would simply add up and all you ve might need to judge is the fact that the total voltage must come within the inverter voltage limit. The higher voltage helps with the voltage drop caused by the large distance and allows the amperage to reach the controller efficiently. Since all the components are connected in a single line the electrical current can only travel in one direction. When you connect the positive terminal of one panel to the negative terminal of another panel you create a series connection.

First of all connect solar panel positive connection with other solar panel negative. One positive and one negative. Here is a very clear picture of how to wire two mismatched solar panels in parallel. However the latter type of connection is at the expense of efficiency.

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. You connect solar panels in series when you want to get a higher voltage. Firstly lets take a look at connecting solar panels in series. In this case it is possible to wire the two 6v panels in series and then wire the resultant array in parallel to the 12v panel.

This is usually the case with 24v systems. Continue this process with all panels.
