Clear, exacting standards are the norm in automotive engineering: low cost, easy assembly, high stability, low maintenance and adaptability. Arausol applies the same principles to its ground-mounted solar systems.
Strengthening the team with solar experience
To support its growth, Arau has added two seasoned solar experts to the management team. Henning Wicht, formerly responsible for solar markets at IHS Markit, and Björn Lamprecht, former managing director at Goldbeck Solar, bring extensive experience in the solar project business.

Based in Schorndorf (southwest Germany), Arausol is digitising its processes across the board. For site planning, the company uses drones to generate precise topographic scans of future project locations. Every site is analysed individually, whether a moor, a former landfill, a motorway embankment or a disused airfield with sealed ground.

Local sourcing and low-impact logistics
The company bases its substructures on steel coils sourced from European suppliers. These are rolled into profiles in Germany and delivered directly to construction sites. Short transport routes help minimise the carbon footprint.
All substructures are manufactured with high-grade corrosion protection as standard. This enables Arausol to offer durability guarantees of 25 to 30 years.

Avoiding delays with smart engineering
Installation procedures benefit from Arausol’s engineering roots. The team continuously refines its methods to avoid costly disruptions. “For example, we reduce the row spacing of modules,” says Henning Wicht. “That allows us to adapt table layouts to dips in the terrain.”
Proven installation teams and a modular, standardised system help streamline on-site execution. Each table measures 31 metres in length and 6.5 metres in width.

Performance by design
A single table supports 27 modules in three rows, typically mounted at a tilt of 10 to 30 degrees. The structure is held by 20 posts. With each module weighing 32 kilograms, the total static load comes to 864 kilograms per table.
Each table delivers 48 kW of solar output. A 20 MW solar park requires about 8,500 posts. Depending on terrain, wind loads and site requirements, foundations are driven 1.5 to 3.5 metres deep.

Stable footing on unstable ground
For challenging soils such as filled ground, Arausol has developed additional stabilisers that can be retrofitted. These post anchoring systems (PVS) are installed next to the existing posts and reinforced with earth nails over a metre long.
Where only selected posts require reinforcement, Arausol supports partial self‑installation. On a site with 10,000 posts, if 280 need anchoring, installers can demonstrate the procedure, enabling operators to complete the remaining work independently. (Leo Fromm/HS/TF)
