Transparency and comparability for optimum results
Our systematic tendering process ensures transparency of the current situation by providing details of the project, such as site analysis and grid capacity and design specifications, such as the DC/AC ratio. We also specify components that the incoming offers must contain, including certain information on components, such as data sheets, explanations on layout and design or the calculation of planned cable lengths. These specifications enable us to make the best possible comparison and subsequent evaluation of the individual offers. In doing so, we highlight certain aspects of the plant layout, the expected yields and questions regarding the most efficient operational management later. We also evaluate the price-performance ratio of the suppliers.
