Does It Matter If My Solar Panels Are Horizontal or Vertical?


It’s a huge decision to install solar panels on your roof. You want to make sure everything is done correctly and you are happy with how your house looks after the installation.

There have been solar systems with panels installed in a vertical orientation. Others, however, are in a horizontal orientation. You might be wondering what the difference is and why it matters if solar panels have a horizontal orientation or a vertical one.

Your solar panel’s orientation doesn’t impact the system’s production. Unless you have a flat roof, which allows horizontal panels to be installed vertically in the US, they will not protrude as much.

Let’s delve a bit deeper and consider why the orientation of your solar panels should be chosen for your home.

Why Are Your Panels Insulated in a Vertical (Portrait) Orientation

You attach solar panels to your roof using “rails.” Because panels are smaller than their height, you will need fewer rails to mount them vertically. You will save money by using less railing!

Vertical orientations work better because the roof’s slope and size allow for more efficient fitting.

This is the most common orientation for solar installation companies.

Why Are Your Panels Installed in a Horizontal (Landscape) Orientation?

  • A flat roof is better than a slanted roof.
  • This is where it’s the norm.
  • A horizontal orientation, due to sun exposure on the roof, will provide more light throughout the day. This will give you more energy.

It doesn’t really matter whether your solar panels are vertical or horizontal. Your solar system is probably designed to meet your needs and preferences. If you are unhappy with the orientation of your solar panels, talk to the contact at the solar company to see if they can help you.

Remember that your solar system’s main purpose is to provide energy to your home. In some cases, it may not be in your best interests to change the orientation of the panels.
