Solar energy protects German vineyards from climate change – DW – 11/30/2025
"VitiVoltaic" projects aim to make viticulture fit for climate change. The term is a portmanteau of the Latin genus name for the grapevine, vitis vinifera, and the word for solar power generation, photovoltaics. This new technology makes it possible to harvest two very different things on two levels: Electricity above and wine grapes below. Pilot projects are underway to test which technology works where — and at what price.
In Germany's southwestern Rheingau region, known for its picturesque vineyards, the Hochschule Geisenheim University (HGU) specializes in all aspects of the wine industry.
