    Optimal integration of photovoltaic systems in the grid

    More and more photovoltaic systems feed electricity into the distribution grid. If the electricity generated locally is not used locally by consumers, this can increase the voltage in the grid. In the PV-Integrated research project, scientists are developing inverter control systems which help stabilise the grid. The new models are currently being evaluated in field tests.  more...
     

    Research funding for the energy turnaround increasing

    Energy research contributes towards the development of the processes and technologies necessary for achieving the goals of the energy turnaround. The German government has been continuously increasing funding for energy research since 2006. In 2013 alone, it spent 100 million euros more on this than in the prior year. This reinforced above all the research areas of energy efficiency and renewable energy sources. It provided just under 300 million euros for each of these subjects.  more...

    Database shows output from renewables

    The sources of renewable energy –sun, wind, water and biomass – account for a large share of the electricity production in Germany. At the beginning of July 2014, solar energy covered the entire peak load. This is shown in the new online “Energy Charts” database at the Fraunhofer Institute for Solar Energy Systems ISE.  more...
     

    “Secure provision of data centres with renewable energies”

    The RenewIT project is researching how data centres can make greater use of renewable energies. That is an important goal for project partner Thorsten Urbaneck, who is a private lecturer at Chemnitz University of Technology. This is because it is estimated that data centres consume two per cent of the electricity used in Europe – and the trend is increasing.  more...

    Less expensive production of thin-film modules

    In the CIGSfab project, the developers have managed to both improve the production of thin-film modules and make them less expensive. In its innovative production line, the Manz AG engineering company has reduced its manufacturing costs by ten per cent. In addition, the company has also made greater use of laser technology and has thus increased the efficiency of the modules by 0.5 per cent. The new production plant therefore makes thin-film photovoltaics a serious competitor for multicrystalline silicon modules.  more...
     

    Energy from a thousand suns

    Multi-junction solar cells were originally developed as energy sources for space flight applications. Their output is high but their manufacture is complex. With their perfectly matched layers, the cells utilise a much wider spectrum of sunlight than silicon cells. For terrestrial use, the multi-junction solar cells are combined with concentrator systems. Like a magnifying glass, these focus a hundred- to thousand-fold concentrated beam of light onto the pinhead-sized solar cells. For this purpose, a solar tracker is used to enable the entire system to track the precise position of the sun. A new record solar cell has achieved an efficiency of more than 44 per cent.  more...

    Where renewable power plants pay off

    With the FreeGreenius simulation programme, engineers can calculate which yields can be achieved by a renewable power plant project at a specific location. In addition, the tool also enables them to plan how the installation must be designed and sized in order to feed in the desired amount of electricity into the grid. Designers of solar power plants and wind turbines can therefore gain an initial insight into whether a power plant is viable and under what conditions. The German Aerospace Centre (DLR) offers the software free of charge for downloading.  more...
     

    Tapping foreign markets with business trips

    The two Renewable Energies and Energy Efficiency export initiatives help small- and medium-sized enterprises to open foreign markets. In order to make contact with potential cooperation partners, they are offering diverse business trips to Europe and the rest of the world this year. The service includes an analysis of the specific interests of the companies taking part. Based on this, the German Chambers of Industry and Commerce Abroad (AHKs) are organising individual meetings for the participants with representatives from business, science and administration.  more...

    More powerful solar cells go into pilot production

    In the SONNE joint project, researchers and companies have cooperatively developed high-performance solar cells and integrated them in glass-glass modules. The process has enabled the module capacity to be increased by more than 20 per cent. In the pilot production, an output of more than 300 watts has been achieved. By way of comparison: modules with 60 cells currently usually have a rated output of between 240 and 260 watts.  more...
     

    Predicting material fatigue of solar modules

    Snow loads, temperature fluctuations and wind gusts: solar modules are exposed to a variety of environmental factors which lead to material fatigue over the years. Researchers at the Fraunhofer Institute for Mechanics of Materials IWM have developed a method of calculating the effects of these influences. Their simulation model predicts when a material will break or peel off.  more...
