Which is better wiring solar panels in series or parallel.

While it may be easier to wire your solar panels in series a disruption to one of the elements will disrupt the entire circuit so it is less reliable. The solar panels in parallel connection have to function around 75 capacity to produce enough voltage for charging batteries. With parallel wiring of the solar panels you will have less voltage and more amperage. Remember you need a greater value of the voltage to charge a battery.

Wiring your solar panels in parallel increases the amperage while keeping the voltage the same. In theory parallel wiring is a better option for many electrical applications because it allows for continuous operation of the panels even if one of the panels is malfunctioning. On the other hand panels connected in parallel need larger more expensive wire and more of it. You must be careful not to exceed the maximum battery system voltage.

Wiring in series is done by joining the positive wire of one solar panel to the negative wire of another panel. If you have two 12v solar panels each rated at 5 amps you will retain the 5 amps but would get a 24 volt charge. When an installer wires your solar panels in parallel each panel s wires are connected to a centralized wire leading from the roof. But it is not always the best choice for all applications.

Wiring solar panels in a series when connecting two or more solar panels in a series your amp charge is stable while your voltage multiplies. The amps of electrical current for each solar panel are summed together but the system voltage stays the same. Wiring your solar panels in parallel results in more wires running from your solar panel system.
