The parallel connection allows to increase the current keeping the same voltage.
How do you wire solar panels together.
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.
When you wire in series there is just a single wire leading from the roof for each string of solar panels.
If we have two or more solar panels with the same voltage but with different current it is not possible to wire them in series.
How to wire solar panels in parallel place the panels close to each other and oriented to the sun at the same angle check that the panels do not shade each other and that they are far from possible causes of shading choose an appropriate section of the electrical cable according to the.
The positive wires are connected to a positive connector within a combiner box and the negative wires are connected to the negative connector.
