What’s The Difference Between Wiring Solar Panels in Series or Parallel?

  • When wiring multiple solar panels together in a system, you have two choices: series and parallel. Determining whether you wire your solar panels in series or parallel mainly depends on your application. Let’s examine the differences and when each method is best.

What’s the Difference? Solar Panels: Series or Parallel

  • The main difference between wiring solar panels in series or parallel is the output voltage and current. When you wire multiple panels in series, their output voltages add together, and their output current remains the same. Conversely, when you wire numerous solar panels in parallel, their output currents add together, but their output voltages stay the same.

Series Solar Panel Wiring

Voltage and Amps in Series

  • To wire solar panels in series, connect the positive terminal on the first panel to the negative terminal on the next, and so on. The resulting voltage will be the sum of all of the panel voltages in the series. However, the total current will be equal to the output current of a single panel.
  • For example, in the graphic above, we have three 18-volt, 6-amp panels wired in series. The output voltage is 54 volts (18V + 18V + 18V = 54V), yet the output current is still 6 amps.

SERIES. What It’s Best For

  • Solar panels in series are optimal in unshaded conditions. If shade covers a single panel of your series array, it will bring down the whole system’s power output. Each panel in a series connection is critical.
    Solar panels in series are also best if you need a low-amperage system. To calculate the output power of a solar system, multiply the voltage by the current. If you have a higher voltage system, your amperage will be lower. Lower amperage allows you to use smaller gauge wires which are less expensive and easier to work with.
    One important thing to know is that you will need to use an MPPT charge controller when wiring your panels in series. MPPT charge controllers regulate the voltage and current from the solar panels to match the battery bank’s voltage without sacrificing power. If you use a PWM controller, the battery will pull the total panel array voltage down to match it, and you will lose a lot of power.

Parallel Solar Panel Wiring

Voltage and Amps in Parallel

  • To wire solar panels in parallel, connect all of the positive terminals on each panel together and then do the same for the negative terminals. The resulting current will be the sum of all of the panel amperages in the parallel array. However, the total voltage will be equal to the output voltage of a single panel.
  • For example, in the graphic above, we have three 18-volt, 6-amp panels wired in parallel. The output current is 18 amps (6A + 6A + 6A = 18A), yet the output voltage is still 18 volts.

PARALLEL. What It’s Best For

  • Solar panels in parallel operate independently of one another and therefore are the best option for mixed-light conditions. If shade covers one or two of your panels, the remaining panels in the array will continue to generate power as expected.
    Parallel solar arrays are also ideal when you want a low voltage system using a lower-cost PWM controller. Again, wiring multiple solar panels in parallel doesn’t change the total output voltage. So, if your panel output voltage matches your nominal battery charging voltage, a series array allows you to increase your output charging current without needing to regulate the voltage.

Solar Panels: Series or Parallel, Which is Better?

Now that we understand the difference between wiring solar panels in series vs. parallel, we can talk about which option is better. So, should you wire your solar panels in series or parallel? Well, again, it truly depends on your application.
Connecting your solar panels in series is often preferred if you’re able to spend most of your time in unshaded locations. The main reason for this is that your solar panel system will be more efficient and will perform better at the beginning and end of the day and when it’s cloudy. Here’s why.
Batteries require a higher voltage than their nominal voltage to charge. For example, our lithium batteries need 14.4 volts to start charging. Most solar panels in the 100-watt range have an output voltage between 18-20 volts. To reach the 14.4 volts required to charge your batteries, solar panels in parallel would need to be operating at 75% capacity or more.

Series or Parallel For Mixing Panel Types

All of our examples have assumed that we are wiring solar panels in series or parallel using identical panels. While this is ideal and is the best option, it is not a requirement. Mixing solar panels from different manufacturers with different electrical ratings is possible, but there are some crucial guidelines to follow.
If you are wiring your solar array in series, all of the panels should have the same current rating. The voltages will still add together, but the current output will be equal to the lowest-rated panel in the series.
In our first example, if one of the 18-volt panels has a current rating of four amps instead of six amps, the output of the whole system would be four amps. This means the total power would drop from about 324 watts (54 volts X 6 amps = 324 watts) to 216 watts (54 volts X 4 amps = 216 watts).
Alternatively, when wiring your solar array in parallel, all of the panels should have the same voltage rating. The system output voltage will match the panel with the lowest voltage rating.
In general, it’s best to use the same panels in each array on a charge controller. To optimize mixing solar panel types using multiple charge controllers with each panel array on its controller will maximize solar output.

Calculate Wire Size From Panels To Charge Controller

  • The solar wire size you need to connect your solar panels to the charge controller is determined by the total amps produced by the array.
    Important: You first need to decide whether your solar array will be wired in series or parallel.
    *If building a solar array this large, consider wiring in series, NOT parallel. This is a safer system (less amps) and components are easier & cheaper to get.

Calculate Wire Size From Charge Controller To Batteries

  • The ideal solar wire size between the charge controller and the batteries is dependent on the amp-rating of your solar charge controller. That’s because the amp-rating of the charge controller is the MAX amount of amps that the controller can send to the batteries.
  • Example: If you have 30A-rated controller but the solar wire connecting it to the batteries is only rated for 20A, you have a potential fire hazard.
    And if the wire is rated for more than 30A, then that’s simply overkill and a waste of money.

Final Thoughts: Proper Wire Size Is About Safety

  • The biggest consideration one should think about when selecting their solar panel wire size is safety.
    If an electric wire cannot safely handle the current fed through it (whether in normal operations or in abnormal overcurrent situations) a fire can happen, which is dangerous to both you and your camper van.
  • Example: If you need a 30A solar charge controller, then you'll need a solar wire with a minimum 30A rating, which is an 10AWG wire.
