What They Do
SONNTAG Energy is a climate-tech startup specializing in agri-photovoltaics (Agri-PV) based in Lindau, focusing on farm-adjacent Agri-PV projects combined with battery storage solutions for agricultural operations (source: sonntagenergy.com). The company offers comprehensive services from planning, construction, and maintenance to electricity sales—all from a single source—with the goal of making farms electrically self-sufficient and economically stronger (source: sonntagenergy.com). SONNTAG Energy develops three main system concepts: protective canopy systems for specialty crops, tracker systems for grassland and arable land, and battery storage solutions designed for self-consumption, energy trading, or both (source: sonntagenergy.com). As a certified electrical specialist company and registered electrical installer, the company places great emphasis on quality and regional proximity, especially in the Allgäu, Lake Constance, and Upper Swabia regions (source: sonntagenergy.com).
Projects & Track Record
SONNTAG Energy specializes in agricultural Agri-PV installations in southern Germany and is currently managing around 40 projects in the planning phase, including a significant project involving apple orchards in Lindau (source: schwaebische.de). A standout project is the installation at the organic fruit farm Jehle, featuring over two hectares of apple orchards and a planned capacity of 2.2 MW, considered the largest project of its kind over organic apples in the region (source: schwaebische.de). Additionally, an Agri-PV system has already been implemented at the Bernhard fruit farm in Kressbronn, which was the largest Agri-PV installation over apple orchards at the time (source: schwaebische.de).
Recent Developments
A major milestone was the acquisition of the Agri-PV business of the insolvent GridParity AG on September 9, 2026, including the "Agri-PV" brand and associated domains, significantly strengthening SONNTAG Energy's market position (source: sonntagenergy.com). The company continues to advance the acquired projects and is increasingly focusing on the combination of Agri-PV, battery storage, and energy trading (source: sonntagenergy.com). Typical projects include PV systems with 1 to 2 MWp capacity and battery storage with 1 to 2 MW capacity, operated via a shared grid connection point and transformer station (source: sonntagenergy.com).
