EWS Sonnenfeld Bruck/Leitha (Lower Austria)
The 5 ha agri-photovoltaic research and demonstration plant is a cooperation project of Energiepark Bruck/Leitha GmbH and EWS Consulting GmbH.
As a particularly innovative "model and lighthouse project for photovoltaics", the EWS Sonnenfeld - Bruck an der Leitha was awarded the contract by the expert jury of the Climate and Energy Fund in August 2021. After two years of product development, the project kick off was in October 2021.
Dual use of agriculture and energy production
Together with Energiepark Bruck and the University of Natural Resources and Applied Life Sciences as partners, research will be carried out in the pilot plant in the coming years to determine which plant cultures and forms of cultivation are best suited to simultaneous PV production.
Even though the technical PV components have already been tested for many years, there are still some open questions regarding the combination with agricultural use. Therefore, a wide variety of technical PV system designs will be tested.
The project serves research and demonstration purposes for the market introduction of agri-PV systems on arable land and grassland.
The solar field and the two reference areas will be equipped with various sensors and measuring instruments in order to be able to investigate the influence of various parameters, such as precipitation, water availability, soil moisture, partial shade intensity, photosynthetic radiation, temperature, wind speed, etc., on agricultural management and the yields of the different crops.

Special features
- In particular, this system is intended to test and optimise the current development status of the EWS Sonnenfeld® in practice for the agricultural use of different crops and types of cultivation.
- In order to be able to investigate the effects on electricity yields and agricultural yields, the movable module table rows are installed with different centre distances: 8, 11 and 14 m centre distances (research zones 2-4).
- So that the effects on biodiversity and the effects on agricultural yields can be studied accordingly, two reference areas will also be considered: A fallow land (research zone 7) as well as an area that is cultivated agriculturally but on which no module tables are erected (research zone 6).
- And in order to be able to compare the electricity yields of the mobile module tables with the electricity yields of fix installed systems, a rigid south orientation (research zone 5) as well as rigid east-west double tables (research zone 8) and a rigid south-east orientation (research zone 1) are also set up on the project site.
- Furthermore, additional and reduced yields of bifacial and monofacial modules with different flowering strip compositions and crops are investigated.
Eight research zones at EWS Sonnenfeld Bruck/Leitha
Research area: 5.5 ha, divided into 8 sections:
1 - South-east orientation, rigid inclination 20°
2 - Sonnenfeld with 6 m cultivation width
3 - Sonnenfeld with 12 m cultivation width
4 - Sonnenfeld with 9 m cultivation width
5 - South orientation, rigid inclination 20°
6 - Unobstructed reference area with agricultural cultivation
7 - Reference area “fallow”
8 - East-west orientation, rigid inclination 16°
* You can see where the different zones are located in the allocation plan.
Status: in operation since 10.11.2022
