Hanwha SolarOne, a PV equipment provider and part of Hanwha Group, has delivered 3MW worth of PV modules for installations at a project owned by the German city of Offenbach.
The 3MW project has been built on 3.7 hectares of land on the steep hillside of a former landfill by Sinusstrom. It was connected to the grid in April and is composed of 12,832 polycrystalline modules which will help to generate an estimated 2.8 million kWh of electricity annually.
During the implementation of the array, the company faced a number of challenges. Anke Johannes, sales director of Germany at Hanwha SolarOne, commented: “Political will and technical competence were crucial in identifying a future-oriented solution for this problematic site. The city of Offenbach and RMN have proven both, and the result is really impressive. We congratulate the Offenbach residents on the new PV park, the area’s largest to date. This is a great example of how public players like municipalities can turn challenging areas into profitable and environmentally-friendly projects. At Hanwha SolarOne, we look forward to contributing to more projects like this in the future.”
The site has undergone a 10-year decontamination process which involved sealing the ground through a capillary barrier which stopped rainwater from trickling through accumulated waste and into the groundwater. Even now, the area’s potentially hazardous groundwater and gases must still be monitored.
After finalising the site’s transformation, remediation company Rhein-Main Deponienachsorge GmbH (RMN) put forward a proposal to build a solar park. However, the area’s capillary barrier had not been constructed to hold additional weight. After proving that a solar park would not affect sealing system operations, RMN was awarded approval from the city council.
