In its role as contractor, mp-tec GmbH & Co. KG is handling the planning and erection of 140 individual systems on a single project. ORCO-GSG, Berlin’s leading provider of office and commercial space, has for many years promoted the sustainable management of its real estate portfolio and commissioned the Eberswalde-based solar system integrator to install 26,200 solar modules on 32 industrial complexes spread across eight Berlin districts by the summer of 2014. The planned systems will have a total output of 6.4 MW. Annual electricity production of around 5,800,000 KWh will save approximately 5,000 tons of CO2 emissions every year.
Thanks to the systems erected by mp-tec, ORCO-GSG will be able to offer around 1,200 commercial tenants the use of the independently generated electricity on favorable terms. This type of electricity use is particularly beneficial to companies, as the load profiles of businesses match the yield profile of the system in an ideal way. Commercial tenants benefit from the attractive pricing of the electricity produced by ORCO-GSG, says Michael Preißel, CEO and founder of mp-tec GmbH & Co. KG.
The project also serves as a best practice example to other business operators who want to use the electricity for their own companies. A key competitive edge, especially as electricity costs are due to rise in the future, says Michael Preißel.
The “snowflake” flat roof system and, for roof-parallel mounting, the “Quick-Line” assembly system developed by mp-tec are used as the substructures on the project. The perfectly coordinated Quick-Line modular system is made of weather-resistant aluminum and stainless steel. It is particularly easy to install, expediting the construction time of the project. Further components for the systems include premium German-manufactured modules from SOLON and inverters from SMA.
Christian Nörenberg, project manager at mp-tec GmbH & Co. KG and responsible for the ORCO-GSG project, explains the benefits of the flat roof system. “Because ‘snowflake’ is an aerodynamic and zero-penetration system, it can ideally exploit the potential of many flat and flat sloping roofs for PV installations. Even roofs with a low load reserve are good candidates for photovoltaic installations with this low-ballast assembly system.”
He goes on to highlight the importance of this project in achieving carbon-neutral electricity production and the example it sets to other cooperative building associations.
“Rising demand for sustainably generated energy increases the appeal of locations which can offer it and thus serves to promote a decentralized energy supply – this is the future!” says Michael Preißel.
