Sunrock, Frasers expand German rooftop solar across five logistics properties

• Sunrock will add 16.5 MWp of rooftop solar to five German Frasers Property Industrial sites, cutting operating costs and emissions for tenants.

Dutch rooftop specialist Sunrock is deepening its partnership with Frasers Property Industrial in Europe, signing on to install another 16.5 MWp of solar across five German logistics and light-industrial properties. The expanded program turns vast, flat roofs into productive assets, lowering tenants’ energy bills, shrinking Scope 2 emissions, and easing pressure on local grids during daytime peaks.

The blueprint is proven but increasingly sophisticated. Arrays will use high-efficiency monofacial or bifacial modules with string inverters and selective DC optimizers on complex roof geometries. Structural engineers validate load allowances and wind uplift for each building; where needed, ballast systems avoid roof penetrations and speed installation. Smart metering segments production by tenant, enabling precise allocation of bill credits under customized power-purchase or on-site consumption agreements.

Grid friendliness is built in. Plant controllers provide reactive power, volt-VAR support and fast curtailment response; export limits can be dynamically throttled to avoid reverse-flow issues on constrained feeders. Where roof layouts allow, Sunrock typically preserves conduits and switchboard capacity for future battery cabinets, turning PV from pure energy into a flexible resource that can shift to evening operations or ride through outages.

For occupiers, the pitch is practical: hedge a portion of power at a discount to grid tariffs without capex, while burnishing sustainability reporting with auditable production data. For the owner, standardized designs and frame-agreements for modules, inverters and racking compress timelines and create maintenance commonality across a pan-European portfolio—lowering whole-life costs and lifting availability.

Community and compliance pieces are now routine. Projects come with lightning protection integration, fire-service access aisles, and insurer-approved cable routing. Biodiversity extras—pollinator planters, green roof sections where viable—help aesthetics and storm-water management. At end-of-life, panels flow into contracted recycling channels to reclaim glass, aluminum and silver.

Germany’s logistics sector is in a race to electrify fleets, deploy robotics and add cooling—raising daytime power demand just as solar is most abundant. By scaling roof PV now and designing for storage later, Sunrock and Frasers are building a template that delivers immediate savings and long-term resilience, five rooftops at a time.
