The Photovoltaics reliability group at ISFH develops innovative measurement techniques and testing methods. These tools are used to assess the reliability and performance of PV modules, components, and materials both in the lab and under real outdoor conditions.
We support industry with:
- Development of new measurement and testing methods for PV modules in laboratory and field settings
- Technical services and expert evaluations of PV modules and materials
- Performance and electroluminescence measurements of PV modules in the lab
- Electroluminescence imaging of PV modules in solar parks using methods that do not require rewiring or nighttime work—unlike conventional techniques
Our work contributes to development projects, certification processes, and custom reliability assessments of photovoltaic products.
With our extensive experience, we provide sound, application-oriented evaluations of new PV technologies—practical, precise, and reliable.
