The year 2026 has kicked off, and installation projects for the upcoming season are being locked in now. Wall-mounted solar installations, in particular, are gaining popularity rapidly, but they require careful planning to be profitable. When the goal is a stylish and technically functional solar facade, the right tools and mounting brackets are decisive.

Solar panels on the wall are one of the most efficient ways to utilize a property's surface area and balance electricity production during winter months. However, wall installation is technically a different world compared to roof installation. It requires more precise planning to ensure the entity is both visually and electrically functional.

January is the best time to plan summer projects. Here are four reasons why professionals choose the RAULI WALL system for their sites and utilize RAULI APP in their planning.

1. RAULI APP – Pricing and Electrical Design in One Tool

Calculating quotes for wall installations can be slow if you have to gather data from multiple sources. RAULI APP streamlines the entire process from the drawing board to customer approval.

The app is not just a component calculator, but a full-blooded design tool:

• Real-time pricing: Get the price for the project’s brackets immediately. This speeds up the quoting process significantly.

• Electrical design: You can plan the electrical functionality of the panel field directly in the app. Select the panels and a suitable inverter, and the app helps you plan the stringing correctly.

• Comprehensive PDF report: The app automatically generates a professional document. With one click, you get production estimates, CO2 emission data for the brackets, a precise component list, and a clear installation manual that even shows the installer the exact sawing lengths for the rails.

When the plan is done right, you avoid surprises at the construction site and can justify your quote to the customer with data.

2. An Architectural and Finished Facade System

On a facade, the installation quality is visible to everyone. Therefore, a "good enough" solution isn't sufficient. RAULI WALL is designed to be visually understated: it leaves the main role to the panels and the building itself.

The system enables a neat, uniform surface without distracting aluminum gaps or protruding parts. Additionally, the color scheme is fully customizable. We use SSAB’s color-coated steel, so the brackets can be delivered in the exact shade suitable for the site – whether it’s a completely "All Black" ensemble or a solution that blends into the facade color.

3. Nordic Steel – Safety Without Compromise

In wall installations, weather stress is harsh, and safety is the number one priority. That is why RAULI WALL is manufactured from SSAB’s high-strength steel.

The material allows for a slender and discreet structure without compromising load-bearing capacity. Domestic steel and high-quality coating ensure that the system withstands demanding conditions without fading or rusting. We grant our products a 30-year warranty, which is a strong message to the end customer as well: this system is built to last.

4. Easy Slide Speeds Up Installation and Improves Margins

Working on a wall is always slower and more expensive than on a roof, as it almost invariably requires lifts or scaffolding. Every extra hour on the wall eats into the project's margin.

Our Easy Slide innovation answers this challenge. The installation mechanism is simple: panels are slid between the rails and locked into place. The installer doesn’t need to support a heavy panel while trying to align screws in a difficult position. When installation proceeds swiftly, lift costs decrease, and the project is completed faster.
