As a Swiss manufacturer of building-integrated photovoltaic systems, we possess in-depth, field-proven expertise from development and production to the long-term operation of BIPV systems.
We use this expertise to provide optimal support for your solar system ensuring maximum energy yield, a longer life, and reliable operation for many years to come. In this way, we work with you to make a tangible contribution to the energy transition.
From planning new systems and analyzing existing systems to assessing damage after hail events - our service team supports you every step of the way.
Professional planning for roofs, facades, and railings
We support architects, installers, and building owners in the development of building-integrated solar systems. Our team of experts creates module layouts, detailed drawings, and construction documents, as well as PV electrical planning - including string design and electrical schematics - to ensure that on-site installation can be carried out accurately, efficiently, and safely.

Standard and custom projects
Condition analysis and performance testing of the solar system
We inspect existing solar energy systems for functionality, output, and safety. To do this, we combine various measurement and assessment methods. Depending on the situation, we use thermography (thermal images) and drone-based imaging, compare the system’s output with actual insolation, measure electrical insulation resistance, and test the functionality of the bypass diode circuit. This allows us to identify sources of loss and defects early on, determine optimization potential, and ensure long-term operation.
Verified plant capacity
Verified security features
Identification of sources of loss and defects
Documentation of the results
Detailed inspection of individual solar modules
We inspect dismantled solar modules in our laboratory for quality, functionality, and damage. To do this, our experts use optical damage detection, electroluminescence imaging, power measurement, and bypass diode testing. This provides you with a clear assessment of the module’s condition.
Detailed imaging of the solar cells
Classification of cell fractures
Measuring the bypass diodes
Documentation of the results
Efficient inspection without climbing onto the roof or dismantling components
After hail events, we assess the integrity and performance of PV systems. Our hail analysis is performed on the installed system using electroluminescence and visual inspection. Damage to bypass diodes and cell fractures are precisely located. The results provide the basis for insurance decisions and restoration plans.
Detection of invisible damage
Precise localization of defective cells or bypass diodes
Comprehensive documentation of the analysis
Advice on repair or replacement
We are happy to provide you with our services and actively support you in tackling any challenges related to solar solutions.
BIPV modules require relatively little maintenance. However, it is important to conduct regular inspections to ensure that the modules are clean and free of damage. Cleaning is usually handled by rain, but in areas with low rainfall or high levels of pollution, manual cleaning may be necessary. Maintenance contracts with specialized companies can help ensure optimal module performance.
BIPV modules are designed to have a long life, comparable to that of conventional PV modules. They typically have a life of 25 years or more. Products from 3S Swiss Solar Solutions AG are characterized by their robustness and durability and are specifically designed for long-term use in building envelopes.
The energy efficiency of BIPV modules depends on various factors, including the type of PV material used (e.g., monocrystalline, polycrystalline, thin-film), the orientation and pitch of the modules, and local climatic conditions. Modern BIPV modules offer efficiency levels comparable to those of conventional PV modules. For example, the modules from 3S Swiss Solar Solutions AG offer high efficiency and are designed to meet the specific requirements of BIPV projects.
