Wirsol

WIRCON Group is a German solar-energy business associated with the WIRSOL brand and based in Waghäusel, in the Karlsruhe district of Baden-Württemberg. The group focuses on photovoltaic projects across the value chain, including project planning, financing, construction, operation, and maintenance of solar power plants. Its scope has included small installations as well as utility-scale developments, giving it a position between a solar-system integrator, project developer, and international renewable-energy services provider. The business began in February 2003 as Hausrenovierer GmbH, founded by Markus Wirth, Hans Wirth, and Stefan Riel. After concentrating on photovoltaics, it was renamed Wirth Solar AG in January 2004 and later became Wirsol Solar AG in 2007. The WIRSOL name was used internationally as the company expanded its project and operating activities. A notable early demonstration project was the Bruhrain solar test park near the Waghäusel headquarters. Opened in 2007, the approximately 12-hectare site was described as the largest solar park in Baden-Württemberg at the time. With about 31,000 modules and a rated output of up to 2.258 MWp, it supplied electricity equivalent to the needs of roughly 500 households. During the late 2000s and early 2010s, WIRSOL developed a portfolio of large solar projects on former industrial and military sites. These included the 848.88 kWp photovoltaic installation at the Hockenheimring, completed in 2010, and major Brandenburg projects at Mixdorf and Luckau. The Mixdorf project used an approximately 81-hectare former Russian fuel depot and reached 24.1 MWp. The Luckau Solar Park, connected to the grid in 2012, delivered almost 21 MWp on the site of the former Alteno military airfield. Such projects reflected the company’s emphasis on converting previously used land into renewable-energy infrastructure. WIRSOL also pursued international expansion. It established offices or operating locations in several European countries, North America, Asia, and the Maldives. In China, co-founder Stefan Riel relocated to Beijing and helped establish Wirsol Solar Technology Beijing Ltd.; a Kuala Lumpur location opened in 2012 to coordinate Southeast Asian activities. A 2012 joint venture, Wirsol RE Maldives, with Renewable Energy Maldives, supported solar installations on six Maldivian islands serving public facilities including schools and hospitals. The company also reported projects in Spain, Italy, Belgium, the United States, Japan, and the Dominican Republic. The original WIRSOL Solar AG entered insolvency proceedings in 2014 after several subsidiaries initiated proceedings between October 2013 and January 2014. In March 2014, assets including the WIRSOL brand were acquired by WIRCON GmbH, a company founded by Dietmar Hopp. The later WIRCON Group therefore represents the continuation and development of the WIRSOL business and brand under new ownership rather than an uninterrupted continuation of the original legal entity. WIRSOL Energy Limited in the United Kingdom was established in 2014 and developed several solar parks. WIRSOL Energy Australia was founded in 2017 and was sold in February 2023. The available reference material does not establish a complete current list of operating subsidiaries, executives, or markets.

WIRCON’s history is rooted in a photovoltaic company established in Waghäusel, Germany, in February 2003. Markus Wirth, Hans Wirth, and Stefan Riel founded the business as Hausrenovierer GmbH. Although the original name suggested general renovation work, the company soon specialized in photovoltaics. It adopted the name Wirth Solar AG in January 2004 and changed its name again to Wirsol Solar AG in 2007, creating the WIRSOL identity used in its domestic and international solar activities. The company’s early development combined demonstration infrastructure with commercial project development. In 2007, it opened the Bruhrain solar test park near its headquarters. The roughly 12-hectare facility contained approximately 31,000 modules and had a rated output of up to 2.258 MWp. It was presented as the largest solar park in Baden-Württemberg at the time and supplied electricity equivalent to about 500 households. The project also served as a visible technical reference for WIRSOL’s ability to design and deliver larger photovoltaic installations. WIRSOL expanded its management and project-financing capabilities as its business grew. In 2010, the board was expanded by founders Markus Wirth and Stefan Riel. Bernd Kästner served as chief financial officer from that period, while Nikolaus Krane, formerly associated with Conergy’s board, was responsible for international financial products, large-scale project financing, and international marketing and communications. In the same year, WIRSOL installed an 848.88 kWp photovoltaic system at Germany’s Hockenheimring. The installation used 4,716 modules along approximately 405 metres of the race circuit. The early 2010s brought a move toward utility-scale developments on conversion sites. In 2011, the company reported revenue of €317 million, according to the cited Wikipedia reference. It also completed a 24.1 MWp solar system at Mixdorf in Brandenburg on an approximately 81-hectare former Russian fuel depot. In 2012, the almost 21 MWp Luckau Solar Park was connected to the grid on the former Alteno military airfield, providing electricity for more than 4,500 households according to the reference material. WIRSOL stated that it had installed more than 6,200 solar systems globally with aggregate output of about 440 MWp, while operating systems were associated with annual carbon-dioxide savings exceeding 180,000 tonnes. Internationalization was a parallel strategic priority. The company established offices or activities in Spain, Italy, the United Kingdom, Belgium, Switzerland, Canada, the United States, China, Malaysia, and the Maldives. Stefan Riel moved to Beijing as an international senior manager and helped create Wirsol Solar Technology Beijing Ltd. In June 2012, WIRSOL opened a Kuala Lumpur location to coordinate Southeast Asian operations. The company also formed Wirsol RE Maldives with Renewable Energy Maldives in 2012. Solar power stations were installed on six Maldivian islands, with electricity supplied to public institutions such as schools and hospitals. Other reported projects included developments in Barcelona and Bovera in Spain, Mola di Bari in Italy, Schilde and Jambes in Belgium, Fort Collins in Colorado, and announced projects in Japan and the Dominican Republic. The original corporate structure came under severe financial pressure in the period from late 2013 into 2014. Several WIRSOL Solar AG subsidiaries initiated insolvency proceedings between October 2013 and January 2014, and WIRSOL Solar AG itself filed for insolvency in 2014. In March 2014, WIRCON GmbH acquired assets including the WIRSOL brand. WIRCON had been founded by Dietmar Hopp, and this transaction created the ownership and organizational foundation for the later WIRCON Group. It is therefore important to distinguish the insolvent WIRSOL Solar AG from the later WIRCON-controlled continuation of the WIRSOL business. The post-2014 organization continued to develop solar assets and subsidiaries. WIRSOL Energy Limited in the United Kingdom was founded in 2014 and realized several solar parks. WIRSOL Energy Australia was founded in 2017 and sold in February 2023; the supplied sources do not identify the buyer or consideration. WIRSOL also had a prominent sports sponsorship relationship in Germany. From the 2011–12 Bundesliga season it was an official sponsor of TSG 1899 Hoffenheim, and the club’s Sinsheim stadium was named the Wirsol Rhein-Neckar-Arena. The naming arrangement ended in the second half of the 2019–20 season, when the venue adopted the name PreZero Arena. The available material does not provide a fully documented current management roster, financial profile, or complete corporate structure.
