Wagner Solar GmbH was founded on 6 August 2014 and on 1 September 2014 took over large parts of the business operations of the insolvent Wagner & Co Solartechnik GmbH. The company develops and manufactures systems for using renewable energies and energy-saving products, in particular solar thermal (manufacture of solar collectors and sale of complete solar thermal systems), solar power (distribution of photovoltaic products and complete systems including battery storage), mounting systems and energy-saving technologies such as heat recovery from shower water. Main customers are specialist installers and OEM clients as well as other commercial and institutional customers in Germany, Europe and other countries; to a limited extent products are also supplied including planning and installation services. Since the end of 2020 all business activities have been concentrated at the Kirchhain site, and Wagner Solar GmbH develops its products in-house.
