New Materials – New Test Requirements:

7th PV Module Reliability Workshop Sets on the Future of the Solar Energy Market

On July 6-7, 2017 the Fraunhofer Institute for Solar Energy Systems ISE is hosting the 7th PV Module Reliability workshop. This year the workshop will be held at the Solar Info Center, which is in close proximity to the laboratories of Fraunhofer ISE in Freiburg. 

 

Press Release #11 / 13.4.2017

CalLab PV Modules Increases Measurement Precision to a Record 1.3 Percent

The calibration laboratory at the Fraunhofer Institute for Solar Energy Systems ISE has achieved a best value: Photovoltaic modules can now be calibrated with an even higher measurement precision of 1.3 percent. Repeatability lies at 0.4 percent. Measurement precision is a decisive factor for quality assurance in the module production and for investments in PV plants. For a volume of 10 MW, for example, each percentage point increase in measurement precision corresponds to a monetary value of about 60,000 euros.

 

Press Release #10 / 10.4.2017

Photovoltaic Inverter with Highly Integrated Concept Promises Lower Costs

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE and its project partners have teamed up to investigate what a new generation of PV inverters aimed at reducing costs could look like.
