On the rooftop of the new business and logistics park “The Tube” in Düsseldorf, Sunrock and Frasers Property Industrial successfully installed a powerful photovoltaic system with a total capacity of 6.7 megawatt peak (MWp).
Sunrock has leased the 76,000 square meter roof area for the project and installed approximately 14,600 solar modules. The system generates 6,039 megawatt hours of clean electricity annually, reducing CO₂ emissions by 2,687 tonnes per year. This contributes to the property’s high sustainability standards and enables climate-friendly energy supply for the tenants.
Green Energy Straight from the Roof: Benefits for Tenants
The solar power generated on-site is made available to the tenants of “The Tube” through a Local Power Purchase Agreement (LPPA). This model offers not only ecological but also economic advantages: fixed prices ensure predictable energy costs, while long-term contracts protect against market fluctuations. In addition, the absence of levies and surcharges makes it possible to obtain green electricity at especially attractive rates. On request, Sunrock can also provide tenants with a full green electricity supply.
Project Execution: From Planning to Operation – All from a Single Source
Sunrock was involved early in the property development process and handled all aspects of the PV project. Construction began in autumn 2024, and despite challenging weather conditions, the system was operational after just six months.
During the planning phase, roof statics and grid capacity were assessed, technical infrastructure and metering concepts were developed, and yield and shading analyses were carried out. After securing all necessary permits, the approximately 14,600 solar modules were installed and connected to the grid. A particular technical challenge was the installation of 44 inverters, which had to be precisely aligned with the roof’s structural requirements.
Even during ongoing operation, Sunrock ensures optimal system performance: its professional asset management includes monitoring, maintenance, regulatory compliance, efficiency and performance optimization measures, as well as regular reporting.
A Sustainable Success Story
“We are pleased that our photovoltaic system makes a significant contribution to the sustainability of the property,” says Roderik von Meyenfeldt, Regional Head of Development at Sunrock. “This project demonstrates how photovoltaics can be integrated into modern commercial and logistics properties in a way that makes both economic and ecological sense – with tangible benefits for the owner and tenants. The collaborative partnership with Frasers Property Industrial was a key factor in this success. We look forward to continuing this successful cooperation and realizing further sustainable projects together.”
Alexander Heubes, Managing Director Europe of Frasers Property Industrial, adds:
“The performance of the PV system is remarkable and significantly contributes to reducing CO₂ emissions during the operation of The Tube. Our goal is for all customers to use the solar power produced on site, and in the future, to intelligently store any surplus energy to optimize the efficiency of our energy supply. We thank Sunrock for the excellent collaboration and look forward to continuing it on future joint projects.”
