Biodiversity and photovoltaics combined in one area
RWA Solar Solutions has realized a pilot project that is unique in Austria. A large-scale photovoltaic system combined with biodiversity areas makes it possible to generate energy in harmony with nature. To this end, a photovoltaic system with around 10,000 solar panels was built on the Garant Tiernahrung site in Pöchlarn. A total output of 4.1 MWp is operated on an area of five hectares, which means that half of Garant’s electricity consumption is used directly.
The “Pöchlarn eco-solar biotope” is divided into two areas. Panels with a south-facing orientation and fixed inclination cover 90 percent of the area. The ground underneath was planted with a species-rich seed mixture and the entire area was surrounded by a biodiversity hedge, creating a habitat for insects, birds, butterflies, amphibians and small mammals. The special installation method using ram profiles allows rainwater to flow between the PV modules, thus avoiding soil sealing. This biodiversity area will be scientifically evaluated by the University of Natural Resources and Life Sciences (Boku) over the next few years.
Three different models of agricultural photovoltaics are being tested on the remaining area. In this sense, the system in Pöchlarn is a role model. The “traveling crop” with rotating panels for optimal processing with tractors, “southern crop” for use with combine harvesters and “power crop” for fruit trees and shrubs. RWA Solar Solutions offers farmers all services from planning and construction to operation and marketing of the energy. The panels protect the crops and the soil from weather influences such as solar radiation, heavy rain and hail. The areas are scientifically managed by the Francisco Josephinum.
RWA Solar Solutions and Frutura cooperate in the field of agricultural photovoltaics
The company Frutura, producer and Austria’s largest marketer of fruit and vegetables, has been won as a partner for the management of the agricultural land.
The Pöchlarn eco-solar biotope combines a unique photovoltaic system with biodiversity areas and a test facility for agricultural photovoltaics. The aim of the project is to generate sustainable electricity in harmony with nature and agricultural use. This enables a significant increase in land efficiency. The focus of the concept was specifically on practical suitability. For this reason, RWA Solar Solutions was also looking for a competent partner to manage the test system.
Frutura tests cultivation with apple trees
Oliver Eisenhöld, Head of Energy at RWA Raiffeisen Ware Austria: “We are delighted to have Frutura as a partner for the use of the test area. The upcoming challenges in relation to climate change and the energy transition can be minimized through concepts such as agricultural photovoltaics. We want to support the regional supply of food and independent energy in the long term.”
The cultivation of apple trees is now being tested on a defined reference area directly below the photovoltaic system.
“Frutura is a pioneer in sustainable agriculture. With the use of geothermal energy, we have set new standards in the year-round, resource-conserving production of fruit and vegetables. By using photovoltaic systems to protect our apple harvest, we are taking the next innovative step. The collaboration with RWA Solar Solutions is an example of how we can make the world a better place together without having to sacrifice quality of life or efficient production,” says Fritz Häupl, Head of Strategic Procurement at Frutura.
Concept to start of construction: April 2019 to Nov 2020
Start of construction until completion: Nov 2020 to Sep 2021
