A solar panel is composed of several small solar cells that can be arranged over a large area to provide enough power to operate. The more light that hits these cells, the more electricity they produce.

How to Wire Solar Panels in Parallel or Series
When it comes to connecting multiple solar panels together in an off-grid system, there are various options when it comes to wiring them. In this article, we’ll talk about the basics of connecting solar panels in parallel and series.
A parallel circuit has multiple paths that allow the current to move along. When an item in the circuit gets broken, the current will continue moving along the other paths, ignoring the broken one. This kind of circuit is commonly used in household electrical wiring. For instance, if you turn off your television, your lights will still be on.
In parallel, the current is additive, but the voltage stays the same. For instance, if you have four solar panels that are each rated at 12 volts, the total output of the system would be 20 amps.
A series circuit has only one path that allows the current to travel through it. This type of circuit is usually used in household electrical wiring. It can prevent the entire system from operating if one of its components gets broken. An example of this type of circuit is a string of Christmas lights. If one of the bulbs in the string breaks, the whole thing will stop working.
In series wiring, the voltage is added to the solar panels’ output, but the amperage stays the same. If you have four panels that each have a rated power of 12 volts, then the system would have a total output of 48 volts.
Like batteries, solar panels have two positive and two negative terminals. The current coming from the negative terminal goes through a load that’s consumed by the panels’ positive terminals.
Wiring Solar Panels in a Series Circuit
- In a series circuit, the first solar panel’s positive terminal should be connected to the negative terminal of the second one.
- If you have four panels that each have a rated power of 12 volts and 5 amps, then the system would have a total output of 48 volts at 5 amps.
Wiring Solar Panels in a Parallel Circuit
- In order to connect all of the solar panels together, connect the positive terminals of all solar panels to one another, and the negative terminals to one another.
- If you have four solar panels that each have a rated power of 12 volts, then the system would have a total output of 12 volts at 20 amps.
