Cleaning agents may damage photovoltaic modules
Photovoltaic modules must be cleaned regularly to optimally utilize the sunlight. Chemical additives are intended to enhance the cleaning effect. However, these can bring with them a high potential for damage. The Fraunhofer CSP has developed a test method to investigate the material compatibility of such cleaning agents and effects on the functionality of modules.

New standardizable method for testing PV module back sheets
Photovoltaic (PV) modules are designed for a service life span of more than 25 years. However, first signs of damage to the electrical insulation can already be observed in many modules after only being in use for 4-8 years. This applies often to modules with polymeric back sheets. The Fraunhofer CSP is working on an improved field-relevant test method for these back sheets. Materials and processes are thereby tested under real operating conditions for an operational service life span of more than 20 years.

New methods to reduce inverter failures in PV systems
Inverters are the essential key component for feeding the electrical energy generated by solar modules into the power grid. How can failures and malfunctions of these inverters be reduced? The Fraunhofer IMWS is investigating this question in cooperation with DiSUN Deutsche Solarservice GmbH and DENKweit GmbH as part of the "robStROM" project funded by the German Federal Ministry for Economic Affairs and Climate Action.
