Solarinvest was one of the leading photovoltaic project developers in Austria during the first European solar boom in the 2000s. To continue its dynamic market growth, Herwig was hired in 2012 as Business Development Manager in order to internationalize the business of Solarinvest. In this role, Herwig undertook several market studies for emerging solar markets such as Turkey, Bulgaria, Chile, Mexico and others. Solarinvest finally decided to enter the Bulgarian and Chilean market as a project developer for grid-connected, large-scale solar projects. Herwig was driving the business development in these new markets. His responsibilities included the complete spectrum of business development, brownfield project acquisition and greenfield project development for ground-mounted photovoltaic power plants.
