Module technology transforms solar cells into durable products for safe operation in PV power plants. Our Module-TEC – Photovoltaic Module Technology Center is equipped with a wide range of modern processing and analytical platforms for connecting and laminating solar cells, especially for material testing, as well as developing products and processes. We apply measurement and simulation to analyze cell-to-module balances (CTM).

The reliability of modules is tested by the team in our accredited TestLab PV Modules for certification according to IEC 61215 and with respect to particular climatic loads and specific degradation risks. We support our clients in qualifying materials and offer comprehensive analyses of degradation and damage to modules. Highest accuracy is also offered by our accredited calibration laboratory, CalLab PV Modules, which is the internationally leading laboratory in this field, with its measurement uncertainty of better than 1.1 % for crystalline modules.

With the five phases of the Fraunhofer ISE quality cycle – development, engineering, procurement, commissioning and operation – we guarantee comprehensive quality control of PV power plant projects. We take site-specific and climatic factors into account to prepare accurate yield predictions and provide advice on the project-specific selection of high-quality components. We develop reliable, probabilistic methods to predict the performance of PV systems.

Based on our expertise in photovoltaics, building science and energy supplies for buildings, we offer solutions to integrate photovoltaics into the building envelope. Our team also develops customized solar modules for special applications such as integration into vehicles and consumer devices.
