Can an odd number of photovoltaic panels be connected in series

If the system sizing calculations result in an odd number of panels (for example, 3 or 5), and you are sure you are not going to add more panels in the future, it’s practical to use either series or parallel wiring.

Question - is it safe/possible to have a 2 panel series and a 3 panel series wired in parallel. Is it ok to have odd number of panels in each group? This would allow me to get at ~100 volts which opens up the market for an all in one. What are the pros and cons of this approach? Thanks!!.

Yes, many large solar panel installations combine series and parallel wiring in one array to maximize the product of each group of panels. It’s possible to strike the optimal balance between series and parallel wiring by carefully planning the wiring based on the location of the panels on the roof relative to the sun and obstacles that .

The thing is, most solar panel systems are larger than 12 panels. So, to have more panels in the system, you could wire another series of panels, and connect those series in parallel. This allows you to have the right number of panels to meet your home’s energy needs, without exceeding the limits of your inverter.

There's really no way to mix odd numbers of the same panels in a series/parallel configuration. Thanks for your help. That would explain why all of the PV wiring diagrams incorporate an even number of panels.

6 FAQs about [Can an odd number of photovoltaic panels be connected in series ]

Should I wire my PV panels in series or parallel?

If you’re worried about the current being too low, consider wiring the four PV panels in parallel. With a four-panel array, there’s no benefit to wiring it in series-parallel. Whether you opt for series or parallel, you’ll require additional cables.

Should solar panels be connected in series or parallel?

Both in series and parallel connection, plugging a panel of a lower power rating to the array drags the whole output power down. The lower the rating, the higher the loss of solar generated power. This, however, is much more crucial for panels connected in parallel.

Are solar panels connected in series?

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.

What happens if a solar panel is wired in series?

Circuits wired in series work the same way for solar panels. If there is a problem with the connection of one panel in a series, the entire circuit fails. Meanwhile, one defective panel or loose wire in a parallel circuit will not impact the production of the rest of the solar panels.

When n-number of PV modules are connected in series?

When N-number of PV modules are connected in series. The entire string of series-connected modules is known as the PV module string. The modules are connected in series to increase the voltage in the system. The following figure shows a schematic of series, parallel and series parallel connected PV modules. PV Module Array

How do you chain multiple photovoltaic modules in an array?

To chain multiple photovoltaic modules — like solar panels — in an array, you must connect them together and to your portable power station or other balance of system. You can do that one of two ways (or a hybrid of both). Series or parallel. But which wiring configuration maximizes your electricity generation potential? Read on to find out.
