The Agri-PV system also makes an important contribution to achieving the ambitious goals of the German energy transition. By 2030, Germany aims to generate 80% of its total electricity consumption from renewable sources, including solar energy. The Agri-PV system is a remarkable step in this direction and impressively shows how innovative technologies can combine traditional agriculture with sustainable energy production.

Agri-PV – A success story for farmers and the environment

The agri-photovoltaic system has the potential to sustainably change agriculture in Germany. Not only does it enable farmers to produce clean energy, but it also protects their crops from the effects of solar energy production. Although the initial investment costs are considerable, this technology pays off in the long term both financially and ecologically. The increasing appreciation of renewable energies by large companies continues to drive demand for such innovative solutions.

The Agri-PV system is a groundbreaking step towards Germany's energy transition, which brings the country closer to its goal of covering the majority of its electricity consumption from renewable sources. It impressively shows how progress and tradition can go hand in hand to create a more sustainable future.

Agri-PV, the abbreviation for agri-photovoltaics, describes the simultaneous use of agricultural land for food production and electricity generation to increase land efficiency. The study of its feasibility and economic viability is in full swing both nationally and internationally. In Germany, the Fraunhofer Institute for Solar Energy Systems (ISE) is significantly active in this area and is cooperating on a fruit tree project in Baden-Württemberg, a model region for Agri-PV. This initiative includes five pilot plants supported with 2.5 million euros. She researches optimal system designs for different crops, the impact of PV systems on yields, and their ability to provide protection from adverse weather conditions.

Potential analysis for Agri-PV

A study by the Lower Saxony Ministry for the Environment, Energy, Building and Climate Protection between October 2018 and July 2020 examined the potential of agri-PV in the region. Apples, asparagus and blueberries were identified as promising candidates for Agri-PV among the cultivated plants in Lower Saxony. With around 17,500 hectares of these crops, an estimated 0.7 to 1.5 gigawatts of installed electrical power could be achieved, depending on the type of installation.

Challenges and opportunities

While major crops such as wheat, corn, sugar beet and rapeseed are currently less suitable due to reduced solar radiation from PV systems, the use of PV modules could compensate for yield losses due to prolonged drought by providing protection against evaporation. Nevertheless, extensive research is required for practical implementation in all applications. Nevertheless, the potential for power generation is significant, with a nationwide estimate of 1,700 gigawatts, driving support for related projects.

Example of success from Germany – despite the bureaucratic hurdles

One of the largest agri-PV systems in Germany is located in Lower Saxony, where a farmer in Wendland grows chives on about one hectare and uses the electricity generated by the PV systems to dry herbs and crops on the same area. Overcoming bureaucratic hurdles was challenging, particularly regarding the use of EU agricultural subsidies for agri-PV, land use planning and environmental regulations.

Future prospects and innovations

Innovations are intended to drive the development of Agri-PV in Germany. Representatives from agriculture, solar technology, research and certification organizations are working on interim standards (DIN-SPEC 91434) that define important aspects of agri-PV such as scope, terminology, criteria and technology requirements. The German Federal Network Agency then defined Agri-PV criteria as the basis for the 2022 innovation tenders under the EEG, with a capacity of 150 megawatts. The new German federal government plans to further advance agri-PV as part of its 200 gigawatt solar initiative and increase the originally planned tender capacity from 50 MW to 150 MW.

The integration of Agri-PV systems into agriculture has a variety of effects on the industry. These systems not only offer a sustainable source of energy, but also help optimize agricultural processes. Here are some key aspects that illustrate the impact on agriculture:

Microclimate zones for plants and animals

The Agri-PV systems cast shadows on parts of the country and thereby create microclimate zones. These zones can be crucial for the growth of certain plant species. Some crops thrive better under slightly dimmed sunlight, and Agri-PV systems offer the opportunity to specifically create these conditions. In addition, animals such as cows or chickens can find protection from excessive heat in the shaded areas, which promotes their health and productivity.

Optimized plant growth

By protecting against excessive sunlight and heat stress, Agri-PV systems can optimize plant growth. The risk of drought damage is reduced because the plants in the shady areas evaporate less water. This results in healthier plants with higher crop yields. Some farmers are already reporting improved quality and increased crop yields through the use of such systems.

Sustainable harvests and animal health

Creating microclimates and protecting against extreme heat contribute to more sustainable agriculture. With fewer stressors, plants can be more resistant to diseases and pests. At the same time, improved animal health leads to higher production rates and better meat or milk quality for farm animals. This is a significant step towards resource-efficient and environmentally friendly agricultural practices.

Agri-PV: A way forward

The installation of Agri-PV systems on farms, such as the Lettenbichler family farm, marks a groundbreaking step towards sustainable and future-oriented agriculture. This development has far-reaching implications:

Environmental protection and energy production

Agri-PV systems enable the simultaneous use of land for energy production and agricultural purposes. This reduces the need for additional space for solar installations and minimizes potential competition between energy production and food production. Switching to renewable energies such as solar power is an important step in the fight against climate change.

Economic benefits for farmers

Investing in agri-PV systems can be economically beneficial for farmers. In addition to the income from energy production, government incentives and support programs can increase profitability. In addition, farmers can feed excess energy into the grid, generating an additional source of income that helps diversify income streams.

Technology and environmental protection in harmony

The installation of Agri-PV systems on agricultural land shows that technology and environmental protection can go hand in hand. Farmers become energy producers while helping to mitigate the environmental impact of conventional agricultural practices. This example shows how innovation and sustainability can be combined to enable efficient and environmentally friendly food production.

Significant progress for agriculture

Agri-PV systems mark a significant step forward for agriculture, offering both environmental and economic benefits and paving the way for a more sustainable and efficient future. The implementation of this technology opens new perspectives for the coexistence of food production and renewable energy production.
