Power Plant Monitoring and Remote Control.
You want to stay informed about the performance of your power plant at all times and anywhere? You want to detect faults quickly and minimize downtimes? SOLON Vega offers you a decisive advantage. Just log into the Internet and you will have all the data at your finger tips.
In countries like Germany and Italy, 5 percent of all electricity already comes from solar cells. But for an even broader breakthrough, even more efficient and inexpensive solar cells are required. To reduce the production cost and facilitate large-scale production, Charlotte Platzer Björkman at Uppsala University will make thin-film solar cells out of completely new materials as a Wallenberg Academy Fellow.
