One of the most important agrivoltaic energy crops in Europe is at present beneath development within the southwestern German state of Rhineland-Palatinate. REG Energy Engineering designed a brand new, energy-efficient materials substructure for the undertaking that enables for livestock grazing.

Agrivoltaics can be found in many various variants. In the municipality of Bruttig-Fankel within the district of Cochem-Zell close to the Moselle River in Germany, PV era and livestock farming are actually mixed on a big scale.
The undertaking will encompass tall, mounted module buildings the place cattle can graze. With a minimal peak of the decrease edge of two.15 meters and a span between the helps of 4 to greater than 5 meters, a medium-sized tractor may drive beneath the module, explains Dirk Kühnel, managing director of REG Energy Engineering and inventor of the mounting system.
The German firm introduced the brand new substructure at Intersolar Europe in Munich. It doesn’t use C-beams, however cold-rolled and galvanized posts and beams with a most materials thickness of three millimeters, added Kühnel. Utility mannequin safety is offered for the type of totally different profiles. Thanks to the brand new design and different good concepts for the meeting, the system not solely saves 30% of the fabric, but additionally quickens the meeting, Kühnel mentioned.
Despite their peak, the very massive module racking system with as much as 15.5 kWp per construction can be utilized as much as wind load stage 2. With a complete output of 69 MW, it is likely one of the largest agrivoltaic undertaking that has been realized in Europe thus far.
First, 4 ramming helps are pushed into the bottom, the place the 4 helps can then be inserted and adjusted to the specified peak. These helps comprise curved edges to cut back the chance of harm to the animals and likewise stand up to the stresses of the cows, defined Kühnel. Two 9-meter-long essential beams are positioned on prime of the helps, to which the 9 module beams are then hooked up. The modules will be mounted by sliding them on the beam profiles. Additional module clamps usually are not required. There is a spot between the modules for rainwater to drip and an built-in cable duct subsequent to it.
The farm, which owns the undertaking web site, hopes that sufficient inexperienced fodder will develop regardless of the shading, which is predicted to lead to higher use of dew and fewer evaporation of rainwater. This ensures an excellent provide of water even in scorching, dry seasons. The farm intends to make use of the pasture for cows and their calves from April to November. Partial shading additionally improves animal welfare. In whole, 34 hectares of the 54-hectare undertaking space can be straight lined by 4,700 PV buildings.
The undertaking, owned and operated by the development and vitality consulting firm Bau-und Energieberatung Marke, is predicted to go surfing within the first quarter of 2025 after the development of a substation.
