Parallel vs Series Solar Panels: What Are the Differences?

Solar panels are the newest fad that promises to reduce your carbon footprint and save the environment. Once set up, you can collect and store power throughout the day. Purchase enough panels, and you can get everything you’ll need to power your home. 

Despite allowing you to minimize your reliance on the electrical grid, solar panels still need wiring like any other electronic device. But how much do you know about your options?

Here’s your guide on parallel vs series solar panels and which one is better for your energy needs. 

Parallel vs Series Solar Panels

Whether you’re installing solar panels on your own or hiring a professional, there are two main wiring methods that are used. Your choice is between series and parallel solar panels. 

The main difference between the two is the output voltage and current. Additionally, the solar panel cost may vary depending on what you go with.

Parallel Solar Panels

This type of solar panel wiring is mostly used in smaller, simpler systems. They usually come paired with PWM Controllers.

When used, parallel wiring allows you to increase your amps while keeping the voltage the same. The reason you would use this is to generate more energy from your panels without exceeding your operating voltage limits. 

Parallel solar panels work well in mixed-light conditions, as each array can generate power independently. 

Series Solar Panels

In contrast, series solar panels are used to increase your voltage level without raising the amperage. This type of wiring works best with smaller systems with lower amperage. 

Solar panels in series work best in direct sunlight. It uses an MPPT charge controller which regulates the voltage and current. Using a PWM controller would result in a loss of power. 

Tips for Solar Panel Installation

Before you install any kind of solar panel array, look up a series or parallel solar panel guide online. Figure out which of them will work best in your yard and with your system. 

Additionally, take a look around your yard or building to see how much direct sunlight your new system will get. If your panels end up partially shaded for half of the day, you may not want to use series solar panels. 

Wiring in series means that each panel depends on one another. If even part of it is in the shade, the entire array produces less power. Panels wired in parallel continue to work effectively even when losing some direct sunlight.

Get Hooked Up the Right Way

Deciding between parallel vs series solar panels could make or break your entire system. They may not work with your specific inverter, or you may find that you’re generating less energy than expected. 

As a quick reminder, parallel connections work in all conditions and have stable voltage. Series connections function best in direct sunlight and maintain your amperage. Your local solar installation company should be able to answer any questions.
