With the launch of our new Solfit 425–435 W Portrait Panel, many installers and developers are asking: what’s the real difference between landscape and portrait in-roof systems, and which should I be using?
Both layouts have their place, but choosing the right one can make a big difference to roof design, installation speed, and overall system output. Here’s what you need to know.
1. Landscape: The Classic Solfit Configuration
Since launch, the Solfit system has been known for its landscape-mounted in-roof design, a format that fits perfectly on most UK house types, particularly new builds and standard roof dimensions.
Key advantages
- Optimised for UK rooftops: Works well with typical roof truss spacing and tile layouts.
Fast installation: Panels interlock horizontally in a modular pattern, allowing two installers to complete systems in hours. - Proven compatibility: Ideal for developers and installers who have built their process around the Solfit system.
Landscape remains a popular choice for large, uniform arrays and when roof width allows for multiple rows without cutting into gable or ridge space.
2. Portrait: Designed for Flexibility and Higher Power
The new 425–435 W Portrait Panel expands the Solfit range to give installers and designers more options. With a taller, narrower format, the portrait system makes it easier to achieve higher power output on more challenging roof shapes.
Key advantages
- Better fit on narrow or complex roofs: Great for townhouses, dormers or properties with height to work with but limited width.
- Higher panel wattage: The new module delivers up to 435 W — helping achieve target kWp in tighter spaces.
Future-ready compatibility: Perfect for mix-and-match use alongside our landscape format to suit multi-plot developments. - Portrait layouts are also increasingly popular with architects who value the vertical alignment for certain roof styles and design symmetry.
3. When to Choose Each System
|
Project Type |
Recommended Format |
Reason |
| New build developments with wide roof spans | Landscape | Fast to install, consistent layout across plots |
| Narrow or tall roof structures (e.g. townhouses) | Portrait | Better roof coverage, higher total output |
| Retrofit projects with limited width | Portrait | Flexible panel spacing and higher wattage per panel |
| Large housing sites needing visual consistency | Landscape | Matches existing Solfit installs and standard training |
Ultimately, both systems deliver the same premium aesthetics, waterproofing integrity, and UK-made quality that define Solfit, the choice simply comes down to roof design and performance goals.
4. Seamless Integration, Same Trusted System
The new portrait panel has been developed using the same all-metal, interlocking Solfit frame design that installers already know and trust. That means no new flashing kits, no unfamiliar fixings, and the same straightforward installation process, just greater flexibility in system design.
5. Ready for the Future of Solar Roofing
With both landscape and portrait options now available, Solfit provides complete freedom to design integrated solar systems for virtually any roof type. Whether you’re optimising for aesthetics, output, or efficiency on site, you can do it all within one proven in-roof platform.
