For Benedikt Ortmann, managing director of the project business at Baywa re, this is groundbreaking.

Researchers from Berlin’s College for Technology and Economics have determined a ‘system performance index’ for 16 residential storage systems. The index ranks systems according to economic efficiency. The compilers of the index say many manufacturers lack transparency regarding system performance.

TOPCon technologies could further increase solar cell efficiencies, said Guangyao Jin, chief scientist, DuPont Photovoltaic Solutions, at this year’s Energy Taiwan, held in September. He added that metallization paste is crucial.

In PERC modules, both light and elevated temperature induced degradation (LeTID) and light induced degradation (LID) must be mitigated. What makes this tricky, however, is that the mitigation process of the first, counteracts that of the second, says Karin Krauß, R&D project manager, Rehm Thermal Systems. At the pv magazine Roundtable in Taipei next week, she will discuss possible solutions with cell and module manufacturers, and EPCs.

During the past three years, Philipp Schröder has built up and consolitaded the Sonnen brand. Now the self-proclaimed “Sonnen Warrior” is going his own way, although he will remain an advisor to the German storage provider. Managing Director, Christoph Ostermann regrets the departure, but emphasizes that with the strong management team that has been established, he will continue to promote the company’s growth.

German battery manufacturer, Tesvolt and EPC Unlimited Energy won the Smarter E award last week, for their innovative off-grid solar plus storage project in South Western Australia. The project demonstrates how solar can provide a reliable energy supply without back up from the grid, and why it is set to spread around the world even faster than many predict.

Insolvency proceedings have been opened on the assets of Photon Production GmbH, which was recently renamed RE Production GmbH. The proceedings were opened upon request of a creditor.

In an interview with pv magazine, Jules Kortenhorst, CEO of the U.S. based Rocky Mountain Institute speaks about the impact of stranded investments, the institute’s partnership with a blockchain start-up, and how the Energy Web Foundation can remain neutral.

Shortly before the announcement of its acquisition by SunPower, SolarWorld’s former U.S. subsidiary commented on the request by its competitors to be exempt from the new U.S. solar PV import tariffs.

The smarter E: First to join Intersolar was the energy storage trade fair EES, and now the concept has become even more comprehensive, the trade fair and conference even bigger. Markus Elsässer, CEO of the organizer Solar Promotion, explains that all of the events now fall under the umbrella of “The smarter E”.
