As a leading solar structure manufacturer, we often get this question from EPC companies, developers, and installers:

“Should we mount panels in portrait or landscape for best results?”

Truth is, both orientations work—but choosing the right one can greatly impact system performance, structural efficiency, and cost.

At SRPL Group, we’ve engineered and supplied solar mounting systems across thousands of projects—rooftop, ground-mount, carports, and more. Here’s our expert take.

Understanding the Basics

– Portrait Orientation – Panels are placed vertically (taller than wide).

– Landscape Orientation – Panels are mounted horizontally (wider than tall).

The choice between the two can influence everything from wind load resistance to structure design and row spacing.

Portrait Orientation: Smart for Limited Space

✅ Advantages:

– Ideal for narrow rooftops or constrained sites

– Helps maximize vertical space—more panels in less width

– Better self-cleaning—rain washes off dust more easily

– Often chosen for residential & commercial rooftops

Keep in Mind:

– May require more clamping points per panel

– Vertical alignment means slightly taller wind profile

Landscape Orientation: Great for Wide-Open Grounds

✅ Advantages:

– Lower profile offers better wind load performance

– Can reduce number of rails or supports in large layouts

– Often used in utility-scale solar farms

Keep in Mind:

– More prone to dust accumulation

– Requires wider spacing between rows to avoid shading

Performance? Structurally Dependent.

From a pure energy output perspective, both orientations deliver similar performance—as long as tilt, azimuth, and spacing are optimized.

But when it comes to structure layout, material consumption, and installation speed—orientation plays a big role.

What We Recommend at SRPL Group

Having supplied 10,000+ solar projects globally, we’ve seen success with both formats. Our recommendation always factors in:

– Project type (Rooftop, Ground-Mounted, Carport)

– Geography & Wind Zone

– Available space

– Client budget

For instance:

– Portrait works well for modular, tight installations (rooftops, carports)

– Landscape suits sprawling layouts (utility projects, flat terrains)

📌 Final Thought

Don’t choose based on trend—choose based on need.

Whether portrait or landscape, the key is working with a trusted structure provider who can customize mounting solutions based on your project’s parameters.
