Avantag Energy, a long-term Premium Partner of IBC Solar, brings together electric mobility and photovoltaics. The new production location of E.Go Mobile in Aachen/Germany will be supplied with electricity from a 750 kW high-performance roof mounted system that was planned and installed by Avantag. The CO2 tyre print of the electric vehicles will therefore already be considerably smaller during production. The investor and operator of the system is Stawag Energie, a subsidiary of the regional energy provider Stawag. A second construction phase with an additional 750 kW will follow in 2019.
Solar self-sufficiency of 45 percent
Solar power and electric mobility – they go hand in hand. Electric vehicles only contribute to climate protection if they are charged with electricity from renewable energy sources. This in mind, E.Go Mobile is going one step further. The CO2 balance of the electric cars should already be as positive as possible during production. The new manufacturing facility in Aachen was therefore equipped with a photovoltaic system. Photovoltaic modules with a total capacity of 1.5 MW will be mounted on the roof in two construction phases and will help vehicle production to achieve a self-sufficiency ratio of 45 percent.
Light-weight mounting sytems for the insulated flat roof
Stawag Energie assigned Avantag Energy, an expert when it comes to the economic and technical dimensioning of photovoltaic systems used for commercial purposes, with the execution of this project. In order to be able to provide the insulated flat roof with as much capacity as possible, Avantag used the particularly light-weighted mounting system IBC AeroFix 10, on which the modules with east-west orientation were attached. Thanks to this aerodynamically optimised assembly variant it was also possible to use a minimum level of additional ballast to ensure that the static reserve of the building does not have to be exhausted.
Residual electricity from a neighbouring wind farm and other regional renewables
The clean energy production on site is supplemented by a contractual residual electricity supply from Stawag. The electricity also comes from regional renewable energy projects here such as a neighbouring wind farm. This cooperation with Stawag Energie offers the benefit for E.Go of being able to use solar power from its own roof from the start of production in the new plant without having to invest itself. This preserves the financial resources for the development of the core business. Stawag Energie is in turn not only investing in a new system for solar power production, but also in long-term customer loyalty.
Around 670,000 kWh are generated each year with the now completed first construction period and are made available for the production of E.Go electric vehicles. The CO2 saving amounts up to 360 tonnes per year. (HCN)
