When cells are connected in series (end-to-end, like a daisy chain), their voltages add up, but the current remains the same as a single cell. For example, if one cell produces 12V, connecting 4 cells in series gives you

The most obvious answer is there is a different number of panels or the panels are oriented in different directions. If the strings have the same number of panels with the same orientation, I might question whether you have a panel or two that is not properly producing.
Learn More Now, if you have both panels in series, you need to make sure they are rated for the same (or "close enough") current, because the electrons must flow through both in turn, and the one with the lower current will limit the whole system. This also happens if one panel is shaded - it appears like it were a less current-generating panel.

That''s sized to carry the current of two panels, with margin. So current from two panels on the right goes out one fuse, back in the other, combines with current of 2nd panel from the left. You now have 3x Isc dumped into the shorted panel.

Shaded panels will contribute less current to the total output, but the maximum output of the panels receiving direct sunlight remains the same. For example, if you have 20 panels that output 3A of current in peak sunlight, but two are covered in shade, reducing their output to 2A, the cumulative output of your array will be reduced by 2A.

The electrician who did the wiring came to look, and explained the reason, i.e. that the neutral was going back to the wrong panel, so the breaker treated it as a ground-fault, since the current wasn''t coming back to the breaker''s panel.)

Do your solar panels share the same electrical characteristics? parallel connection forces all the system to have the same voltage and the series connection forces all the system to have the same current.

The main panel needs a neutral for the current to flow through the circuit and a ground wire to provide protection in the event of a ground fault.

But to do that the panels Current Specs have to be the same because the lowest panel current rating dictates the maximum current a series string will pass.

To be clear the subpanel will be attached to the same structure as the main panel (the main panel does have a grounding rod), just on the opposite side from the main panel.

No, the parallel strings will not affect each other if one is shaded. Paralleling strings/panels is the solution to shading issues. Another option, depending on whether you can or want to put 3 panels on your roof would be to make 3 distinct strings: 2 panels in series on roof, 2 panels in series, 2 panels in series.

Power is Voltage * Amperage, right ( In DC circuits )? So to increase power you can: keep voltage the same but rise the amperage or rise the voltage but keep the amperage the same (or rise both ). In this case, to rise the amperage, you connect two panels in parallel. Their voltage stays the same, but current doubles.

With series wiring, the voltage of the panels adds together while the amperage (current) stays the same. Example: If you have four 100W solar panels wired in series and each panel outputs 5A at 20V, your array would output 5A at 80V (4 panels x 20V = 80V). That 80V output is in full sun.

Panels in series limit the current to that generated by the smaller panel, voltage is the sum of the panel volts. Thus panels in series should have similar current outputs. Panels in parallel deliver the sum of the currents, panel volts for maximum power need to to be similar, +/- 1 volt on 20 volt panels, +/- 2 on 40 volt panels.
Learn MoreWhen you connect solar panels in parallel, the total output voltage of the solar array is the same as the voltage of a single panel, while the total output current is a sum of the currents passing through each panel. The latter is only valid provided that the panels connected are of the same type and power rating.
When you connect solar panels in series, the total output current of the solar array is the same as the current passing through a single panel, while the total output voltage is a sum of the voltage drops on each solar panel. The latter is only valid provided that the panels connected are of the same type and power rating.
The difference between these two types of configurations is the total Voltage (Volts) and the total Current (Amps) of the solar array. When you wire solar panels in series, you raise the Voltage of the system, while the Current stays the same. Voltage: Total Voltage (Volts) = Voltage 1 + Voltage 2 + Voltage 3 + Voltage 4
Connect only in series panels of the different brands and of the same current. Connect in parallel panels of different brands and of the same voltage. Connecting different solar panels in a solar array is not recommended since either the voltage or the current might get reduced.
Thus the effect of parallel wiring is that the voltage stays the same while the amperage adds up. Photovoltaic solar panels generate a current when exposed to sunlight (irradiance) and we can increase the current output of an array by connecting the pv panels in parallel.
If you, however, need to get higher current, you should connect your panels in parallel. Should you need both a higher voltage and a higher current, you have to apply both connection modes, which means that a part of your solar panels should be wired in series, while the remaining ones are to be wired in parallel.
