When setting up solar panels for your home, it’s crucial to know the best way to link them together to get the most power. There are two main ways to do this: series and parallel. Each method has its benefits, and the right choice depends on what you need from your solar power system. Solar Planet is here to help you understand these options and connect you with up to four MCS-accredited installers in your area who can tailor the setup to your specific needs.

Series Configuration: Boosting Voltage


Linking solar panels in series means connecting the end of one panel to the start of another. This setup is great for when you need more voltage. It’s like adding batteries to a flashlight; the more you add, the brighter the light.

Benefits of Series:

  • More Voltage: Each panel adds its voltage to the total, giving your system a big boost.
  • Good for Long Distances: If your solar panels are far from where the power is used, a series setup helps keep the energy strong on its journey.
  • Better for Certain Inverters: Some systems need higher voltage, and series connections can be a perfect fit.

Series vs Parallel Solar PanelsParallel Configuration: Increasing Current


With parallel connections, you link all the positives together and all the negatives too. This way, the voltage stays the same, but you get more current flowing through the system.

Benefits of Parallel:

  • More Current: This setup pulls together the power from each panel, giving your system a higher overall output.
  • Shading Isn’t a Big Issue: If one panel gets shaded, the others keep working fine, so your power doesn’t drop too much.
  • Easy to Add More Panels: Want more power? Just add more panels without complicating things.

Choosing What’s Right for You


The choice between series and parallel (or a mix of both) hinges on several things, like how your inverter works, whether your panels might get shaded, and how much room you have for them.

Series and Parallel Together: The Best of Both Worlds


Often, combining series and parallel gives you the most flexibility. You can get the voltage and current just right for your needs by connecting some panels in series and then linking those groups in parallel.

Frequently Asked Questions

Can I really choose how my solar panels are connected?

Yes, solar panels can be connected in either series, parallel, or a combination of both. The best configuration for your system depends on various factors like your home’s layout, shading, and energy needs.

What are the main advantages of connecting solar panels in series?

Connecting panels in series boosts the overall voltage of your system, which is beneficial for compatibility with certain inverters and efficient for long-distance power transmission.

Why might I prefer a parallel configuration for my solar panels?

A parallel configuration increases the system’s current while keeping the voltage constant. This setup is less affected by shading on individual panels and allows for easier expansion of your solar system.

Is one configuration better than the other in all cases?

No, the best configuration depends on your specific situation, including potential shading, the distance between your solar panels and inverter, and the specifications of your solar energy system.

How can Solar Planet help me decide between series and parallel?

Solar Planet connects you with up to four MCS-accredited solar installers in your area who can assess your property and energy needs. They’ll recommend the optimal configuration for efficiency and effectiveness.

Can shading really affect the performance of my solar panels?

Yes, shading can significantly impact the performance of solar panels. In a series configuration, shading on one panel can reduce the output of the entire string. Parallel connections are less affected by shading on individual panels.

What if my home needs a combination of both series and parallel connections?

Many systems benefit from a series-parallel configuration, which combines the advantages of both setups to meet specific voltage and current requirements. Your installer can design a system that uses both configurations for optimal performance.

Will choosing a particular configuration affect the cost of my solar panel installation?

The cost can vary slightly depending on the configuration due to differences in wiring and potential additional equipment. However, choosing the most efficient setup for your needs can lead to greater savings on your energy bills in the long run.

What our customers say

I was thinking about getting solar for my home and stumbled upon www.solarplanet.uk. The site's super easy to get, breaking down all the solar jargon. After reading up for a bit, I filled out their quote form. The next day, I got calls and emails from three solar companies in South Wales. Chatted with all of them, got quotes, and went ahead with one. The whole experience was smooth, and all the companies seemed top-notch. Big thumbs up!

Running a business, those rising energy bills were starting to pinch. So, we thought, 'Why not try solar?' A quick online search led us to Solar Planet. Filling out their quote form was a breeze, and guess what! The very next day, three solar experts from Bristol gave us a shout. They were all super helpful and knew their stuff. Picking one was tough since they all had great offers. And a big relief! They all had this MCS accreditation – a real peace of mind with all those dodgy stories you hear these days.

Daniel JonesOn The Blink - Commercial Business in Bristol

It couldn't have been easier! Initially, we were scratching our heads trying to find a trustworthy company. Then, thanks to a quick Google search by my husband, we landed on Solar Planet. He filled out their quote form, and the next day, three different solar installers rang us up. We've been over the moon with both the installation and the ongoing support. They guided us through the whole process from installation to helping us find the best energy provider for solar power.
