Overview

Sinosol was a German-Chinese company in the solar sector headquartered in Stuttgart, Germany. It operated as a photovoltaic system wholesaler with branches in Germany, Italy and China, and it also projected, installed, operated and maintained photovoltaic installations. The business thus combined distribution of solar components with project development and downstream services. The company was publicly listed: the Sinosol AG Inhaber-Aktien O.N. were quoted in 2012 with the suffix "n. a." Its three-member supervisory board in 2011 consisted of Kurt Ochner as chairman, Ulrich Hemel as deputy chairman and Rongzhang Li. The company's project references included large ground-mounted solar parks such as the 7.5 MWp "Nordendorf" solar park near Augsburg, Germany, on 16 hectares; the 3.3 MWp "Breitenau" solar park in the municipality of Obernzenn, Germany, on 7 hectares; and the 15 MWp "Almería" solar park in Spain on 30 hectares. It also realized off-grid systems, including street lighting in Beijing, a 95 Wp module for the self-steering system of the Mini Trans 650 sailing boat, and an autonomous 360 Wp power supply for the Roter Sand lighthouse in the North Sea. At the annual general meeting of Sinosol AG on 29 September 2014, it was resolved to liquidate the company in 2015. The domain sinosol.de is now offered for sale, indicating that the brand is no longer operating. Sinosol is therefore best understood as a defunct German-Chinese solar wholesaler and project developer rather than an active brand.
