Connecting 3 Solar Panels In Series

This is the first part of our video on how to connect your panels in series and parallel.

Connecting 3 solar panels in series. The connection of multiple solar panels in parallel arises from the need to reach certain current values at the output without changing the 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. The video will go over the basic installation and can apply directl. Solar panels are wired in series when you connect the positive terminal of one panel to the negative terminal of another.

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 you connect two or more solar panels like this it becomes a pv source circuit. The 140w panel actually drags the 3 other 160w panel s wattage down to 140w as well meaning we effectively have 4 x 140w solar panels. By connecting multiple solar panels in series we increase the system voltage.

The first way i am going to talk about is parallel because this is probably the most common way that panels will be connected. Connecting solar panels in series. In fact by wiring several solar panels in series we increase the voltage keeping the same current while wiring them in parallel we increase the current keeping the same voltage. 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. This kind of a lowering of current would of course cause a loss of power output and eventually loss in equipment efficiency. There are 3 ways to connect solar panels. After these clarifications let s see how the series connection takes place.

When installing solar panels in series the voltage adds up but the current stays the same for all of the elements. For this example i am showing you connecting panels that are for a 12 volt system. Typically solar panels of specific or matching current needs to be connected with each other in series. 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.

The connecting solar panels in series is very easy just like connecting battery cell with one anther however lets get a review on.
