Connecting 3 Solar Panels In Series

Solar panels are wired in series when you connect the positive terminal of one panel to the negative terminal of another.

Connecting 3 solar panels in series.

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. When you wire in series there is just a single wire leading from the roof for each string of solar panels. Typically solar panels of specific or matching current needs to be connected with each other in series.

This kind of a lowering of current would of course cause a loss of power output and eventually loss in equipment efficiency. 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. 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. By connecting multiple solar panels in series we increase the system voltage.

This is the first part of our video on how to connect your panels in series and parallel. Should you connect a 3a solar panel to a 3 5a solar panel the all round current will probably be pulled down to 3a. There are 3 ways to connect solar panels. When installing solar panels in series the voltage adds up but the current stays the same for all of the elements.

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. Parallel series and a combination of parallel and series. So when connecting solar panels in series always try to keep the electrical properties of the solar panels identical to get the full benefit of the solar array. For this example i am showing you connecting panels that are for a 12 volt system.

When solar panels are wired in series the voltage of the panels adds together but the amperage remains the same. The first way i am going to talk about is parallel because this is probably the most common way that panels will be connected. The connecting solar panels in series is very easy just like connecting battery cell with one anther however lets get a review on.
