A logistics center in Horsens, Denmark is set to host what will be the world’s largest rooftop solar installation — a 35-megawatt system sprawling across more than 300,000 square meters of industrial rooftop. The project, awarded to Danish solar firm SolarFuture ApS, would surpass every comparable rooftop installation on record, including solar arrays at Tesla’s Nevada and Texas Gigafactories.
At a glance
- Rooftop solar capacity: The Horsens installation will generate 35 MWp — comfortably exceeding Tesla’s Giga Texas, which is estimated to reach around 30 MWp, and Nevada’s Gigafactory at roughly 8 MWp.
- DSV logistics center: The host building covers over 300,000 square meters, ranking it among the five largest buildings on Earth by floor area, with the majority of its roof surface dedicated to panels.
- SolarFuture ApS: The Albertslund-based company, founded in 2014, has previously completed solar installations on the roof of the Copenhagen Opera and at several sites along the Øresund Bridge connecting Denmark and Sweden.
Why a logistics warehouse matters for solar
Rooftop solar on industrial buildings has long been seen as underused potential. Warehouses and distribution centers offer vast, unobstructed roof surfaces — often sitting in areas where land is at a premium and energy demand is high. The challenge has always been structural: older buildings weren’t designed to bear the weight of panels, and the economics only pencil out at significant scale.
The DSV facility in Horsens clears those hurdles. Because the building is new and purpose-built, the roof can be engineered from the start to support the installation. At 300,000 square meters, the available surface is simply enormous — equivalent to around 42 soccer pitches. That scale is what allows a logistics center in a small northern European country to set a global benchmark.
SolarFuture CEO Mads Christensen described it as “a landmark project for the entire solar industry.” He added that a specialist team has been assembled to ensure rapid installation, with the goal of completing the system by December 2024 C.E. — a tight but deliberate timeline.
Denmark’s quiet solar ambition
Denmark is better known internationally for wind power, which supplies a dominant share of its electricity. But rooftop and industrial solar has been growing steadily, supported by strong corporate sustainability targets and a grid that increasingly needs flexible, distributed generation to complement offshore wind.
Projects like this one reflect a shift in how large companies think about energy. DSV, a global logistics firm headquartered in Denmark, is among a growing number of corporations treating on-site renewables as a core part of operations rather than a side project. A 35 MW rooftop system could generate enough electricity annually to power tens of thousands of Danish homes — though in this case, the energy will primarily serve the facility itself.
SolarFuture’s track record includes technically demanding installations, not just large ones. Its work on the Copenhagen Opera — a landmark building with a complex curved roof — showed the firm could handle projects where standard approaches don’t apply. The Horsens project demands a different kind of expertise: sheer logistical coordination across a roof the size of a small town.
For context, the International Energy Agency has identified rooftop solar as one of the fastest-growing sources of new electricity capacity globally, with industrial and commercial rooftops representing a largely untapped share of that potential. The International Renewable Energy Agency estimates that rooftop systems could eventually supply a significant fraction of global electricity demand if deployed at scale on suitable buildings.
Scale, scrutiny, and what comes next
The “world’s largest” claim deserves a note of honesty. Rooftop solar records are genuinely difficult to verify — installations vary by how capacity is measured, whether figures are peak or average output, and how “rooftop” is defined versus ground-mounted systems built against a structure. The U.S. Department of Energy tracks large solar installations but rooftop records aren’t centrally catalogued in the same way utility-scale projects are.
What is clear is that 35 MWp from a single rooftop is genuinely exceptional by any current standard. Whether it holds the record indefinitely is another matter — Solar Power Europe projects continued rapid growth in large commercial solar across the continent, and several projects in Asia are also pushing into this territory.
There is also the broader question of whether one flagship project translates into wider adoption. A single record-breaking installation demonstrates what’s possible, but replicating it across thousands of suitable industrial rooftops requires policy support, financing structures, and grid capacity that remain uneven across markets. Denmark’s own grid infrastructure is well-suited to absorb distributed solar, but that isn’t true everywhere.
Still, records have a way of shifting expectations. When a logistics center in Horsens, population 60,000, sets a global benchmark in solar energy, it makes the idea of ambitious rooftop installations harder to dismiss — for building owners, policymakers, and investors alike.
