What is a solar panel? There is more to it beneath the panels, like two main writing configurations – solar panel wiring series vs parallel. But what is the difference between the two?
Keep reading this fundamental solar panel guide with us to answer these questions!
Solar Panel Wiring: Series or Parallel, What’s the Difference?
The main difference between the series and parallel connectivity is that the wiring connections have a voltage difference. The solar panel’s wiring adds the amperage or voltages together and, in turn, keeps it the same or amplifies it.
Parallel wiring is typically used when smaller systems are installed, but it uses more equipment. All the panels work together based on the combined voltage power from the individual solar panel. When connected, the amps increase and the voltage stays the same.
Series solar panel wiring has the opposite effect. It tends to add the voltages together, but they have a low amperage system. You can also use fewer, smaller wires, but you must use an MPPT charge controller.
Series solar panel wiring is where each panel becomes an individual connection. This wiring type is typically used in larger systems as it uses less equipment, but the voltage drop may be higher. The downside to series is that the entire system can go down if one of the panels fails.
Some solar companies will combine parallel series solar panel wiring to get the best performance for their clients. Depending on their application, whether it is your home, RV, or solar carports. Series solar panel wiring allows more energy to be collected per panel, while parallel wiring spreads the load among more solar panels.
Which Wiring Works Better Between Series or Parallel?
When it comes to wiring, there is much debate amongst people and experts as to which wiring type is better.
So, what’s the verdict? In a nutshell, series solar panel wiring involves all the solar panels being connected while needing to stay in the sun. The main factor to remember here is that voltage increases when it’s cloudier, not hotter, creating higher output.
Parallel wiring can be easier to install, but it can also result in a loss of power if not done correctly. It also requires partial shading to create higher output. Always consult a licensed solar installation expert like Blue Raven Solar when upgrading your wiring!
Series wiring is what many would consider being the better option, as it offers higher voltage and more current flow than parallel wiring. However, parallel wiring is typically more efficient in the long run and is becoming more popular due to its low voltage requirements.
So, the decision of wiring solar panels in series or parallel is ultimately up to you – but consult with a professional to get the best results.
The Bottom Line on Solar Panel Wiring Series vs Parallel
