Investing in the Energy Supply of Tomorrow

Fraunhofer ISE’s New Research Lab for Power Electronics and Grid Technologies in the Multi-Megawatt Range

With the grid expansion and modernization process for the German energy transformation, a growing number of applications for advanced power electronics and grid technologies arise. Power electronic devices, or converters, are key for connecting power supplies, consumers and storage systems and are playing an ever more important role in our energy supply. Further, these devices must be tailored to meet the increasingly complex requirements that ensure the flexible and reliable operation of our future energy system. Against this background, the Fraunhofer Institute for Solar Energy Systems ISE is constructing a new lab site for the research, development and testing of the grid integration of renewable power, including controls for the low, medium and high voltage grids. Already most of the impressive lab infrastructure has been acquired and installed, and the new facility in the industrial area in North Freiburg is taking concrete shape.

Fraunhofer ISE Develops Freeware “Aircow“ to Calculate Solar Air Heating Collector Fields

Until a few years ago, solar air heating collector systems have received only limited attention on the market compared to fluid heating collector systems. Solar air heating collectors are more difficult to measure and to evaluate. This not only hinders the development of new products but also provides less transparency on existing products. In the meanwhile, a more detailed measurement method has been incorporated into the test procedure for solar thermal collectors (DIN EN ISO 9806). On this basis, Fraunhofer ISE created an MS Excel application in order to improve air collector evaluation and system planning. The calculated results serve to certify solar air collectors according to Solar KEYMARK, to design system layouts, to develop air collectors as well as to perform parameter variation studies.

Fraunhofer ISE Organizes Workshop “Energy Flexible Buildings” to be Held at the ISH 2017 in Frankfurt

The expansion of renewable energy sources impacts the entire energy system in a variety of ways. Both the functions of the individual components, i.e. supplier, consumer and storage, as well as their interaction with each other must be redefined. Buildings themselves will also have to take on new roles. They must be able to react flexibly to the conditions in the energy system, orienting their operation more on the energy production than demand.

Fire Broke Out in Fraunhofer ISE Laboratory at Solar Info Center, Freiburg

At mid-morning today on Friday, February 24, 2017, a fire broke out in one of the laboratories of the Fraunhofer Institute for Solar Energy Systems ISE located in the Solar Info Center in Freiburg. The fire alarm was immediately set off and the building was successfully vacated. The firefighters were on location immediately and brought the fire quickly under control. According to the Fire Service, four firefighters were injured. A forensic investigation to determine the cause of the fire is underway. The building is presently closed and entry is not permitted. The Fraunhofer Institute for Solar Energy Systems ISE will report more information as it is confirmed.

Software Reduces Losses in Solar PV Modules

A photovoltaic module consists of many interconnected solar cells. One cannot say, however, that the module power is simply the sum of the individual cells. Power losses due to reflection, absorption or electrical losses come about in the integration process. These cell-to-module, or CTM, losses have a large effect on the subsequent module performance and […]
