Comparing Ground Mount vs Roof Mount Solar Systems

There are a couple different types of installation methods for solar panels. Here at 15 lightyears, we install roof mounted solar panels as well as ground mounted solar panels. These installation types accomplish different goals, and what works for one customer may not be the best option for other customers.

Before diving into the list, let’s first define what a ground mount and roof mount solar system is.

 

Roof Mounted Solar Panels

A roof mount is the most common type of installation. This is when the solar racking, which holds the panels in place, is installed directly on the roof. Panels can be attached to flat or sloping roofs consisting of metal, shingle, or rubber materials.

 

Ground Mounted Solar Panels

A ground mount is when the panels are secured to a rack structure that is connected to the ground with steel beams or another type of metal post. Ground mounts can be installed in an open area or as a carport over a parking lot.

Ground mounts can be installed wherever the conditions are best for solar, making them a great alternative for someone who doesn’t have enough usable roof space or just prefer to not have panels mounted to the roof.

 

Advantages and Disadvantages

Both types of installations have their  plus and minuses. Let’s take a look at those.

Roof Mounts: Pros and Cons

Pros:

  • Roof mounts utilize space that otherwise wouldn’t be used.

  • Typically the installation cost is lower compared to a ground mounted system

  • Doesn’t take up land that could be utilized for other activities

  • Limits unauthorized visitors from accessing the panels 

  • Panels can protect the roof from exposure to certain elements

Cons:

  • Roof penetration is required for shingle roofs

  • Could require a new roof before installation

  • Adds weight to your roof, and in some cases, the roof could require additional support mechanisms

Things to consider:

  • The age and condition of your roof

  • The impact solar could potentially have on your roof warranty

Ground Mounts: Pros and Cons

Pros:

  • Ground mounts can be installed in any direction or location, positioning them for optimal energy production

  • They can be installed at multiple angles

  • The system can easily be accessed for maintenance

  • Carports can be installed in existing parking lots - providing shading and protection to parked cars

Cons:

  • Typically the installation cost is higher

  • Limits the use of the land

  • Takes up large areas

  • Easier access for unauthorized visitors

  • Increased chance for accidental damage from rocks or other particles thrown from a mower and other equipment

  • Likely requires mowing around multiple posts and under low clearances

Things to consider:

  • The long-term plan for the plot of land

  • The terrain of your property
