3S Software Suite
Smart software solutions for 3S solar systems.
The 3S Software Suite, comprising 3S Designer and 3S Horizon, complements our solar systems with smart, intuitive tools that ensure greater quality, efficiency, and transparency along the entire value chain—from initial planning and execution to the operation of a 3S solar system. As a developer and manufacturer, we combine our technical expertise with digital solutions that provide targeted support to installers, planners, and owners of PV systems and simplify processes.
3S Designer
The innovative software solution for intuitive planning of the 3S solar roof.
The 3S Designer is a professional planning tool for the simple, visual, and standard-compliant design of in-roof photovoltaic systems with the 3S system. The tool guides the user through the entire process, from project planning and roof input to the finished 3D design and documentation.

Overview of features and benefits
In March 2025, the 3S Designer received an upgrade with 3D building and roof recognition, making the work of planners and installers even more efficient. Based on building data that is available and standardized in Europe, roofs can be automatically captured in a matter of seconds, significantly reducing the amount of work involved.
3S Horizon
Intelligent solar management. Made easy.
Coming soon: 3S Horizon is the intelligent all-in-one platform for simplifying solar energy management. It optimizes energy consumption, ensures that PV systems operate at maximum efficiency, and keeps track of energy flows at all times. 3S Horizon is a powerful software solution that makes solar systems smarter – for homeowners and professional installers alike. 3S Horizon – more control, more yield, more future.

For installers
3S Horizon is the smart platform for managing and monitoring your system installation portfolio. Advanced diagnostics, extended fault detection, automatic performance analyses, intuitive visualizations, and automated insights enable you to provide your customers with first-class service and support throughout the entire life cycle of their PV system. This strengthens customer relationships and increases your business success.

For PV system owners
3S Horizon is the all-in-one solution for optimizing solar energy consumption. Owners of PV systems can easily integrate battery storage, heat pumps, e-charging stations, and household appliances into a unified ecosystem. This maximizes the benefits of solar energy by increasing self-consumption, feeding surplus energy into the grid, and contributing to a sustainable energy future. Thanks to integrated monitoring with intelligent fault detection, installers can quickly identify and efficiently rectify malfunctions or defects throughout the entire service life of the PV system. This ensures that the PV system always operates at maximum performance.
