Agrivoltaics involves the use of agricultural land to produce food and generate solar energy simultaneously. Conventional free-standing installations can also provide a valuable habitat for flora and fauna, which in turn promotes the acceptance of both the installations and the energy transition as a whole.
Munich/Pforzheim, February 11, 2021 - Photovoltaics (PV) is booming in Europe, with around 18.7 gigawatts of new capacity installed last year. In addition to rooftop and ground-mounted solar module installations, the development of new areas of production - such as on façades, artificial bodies of water and fields - is key. Agrivoltaics involves the use of agricultural land to produce food and generate solar energy simultaneously. Conventional free-standing installations can also provide a valuable habitat for flora and fauna, which in turn promotes the acceptance of both the installations and the energy transition as a whole. Find out more about new developments and potential applications for PV at Intersolar Europe, the world's leading exhibition for the solar industry, and the accompanying Intersolar Europe Conference. Both events will be held as part of The smarter E Europe from July 21 to 23, 2021, at Messe München.
In Germany - by far the EU's largest PV market - 4.8 GW of solar capacity were added last year, and renewable energies accounted for more than 50 percent of net public electricity generation, i.e. the energy mix that actually comes out of the socket. However, market researchers warn of a potential gap in the German energy supply as early as 2023. To ensure supply security and achieve climate targets, the current rate of photovoltaic expansion must double by 2021 and triple by 2022. In the interest of promoting photovoltaic expansion and using space efficiently, solar modules are no longer limited to rooftop installations and free-standing systems. In the future, modules on façades, agrivoltaics and floating PV could open up even more production areas, making them an additional driver of photovoltaic growth.
Photovoltaics above, photosynthesis below
Agrivoltaics is a method for the shared use of agricultural land for food production and PV power generation. It improves land use efficiency by allowing for the expansion of PV power generation while also preserving arable land for agricultural use. Photovoltaics and photosynthesis are no longer in competition, but rather complement one another. In light of the dynamic global growth of PV and the associated increase in the land area required for PV installations, innovative concepts such as agrivoltaics support the transformation of the energy system through the dual use of agricultural land.
According to the Fraunhofer Institute for Solar Energy Systems ISE, agrivoltaics technology has made significant progress in recent years and has spread to nearly every region in the world. The agrivoltaics capacity installed worldwide has grown from around five megawatts (MW) in 2012 to approximately 2.9 GW in 2020, with China producing the greatest share of installed capacity at around 1.9 GW. As climate change leads to increasing droughts and extreme weather events, agrivoltaics offers multiple advantages: zero-emission solar power plus food production plus the protection of crops from drought and damage caused by extreme weather such as hail or strong rain. By partially shading agricultural areas, the solar modules reduce the rate of evaporation and can also replace expensive hail netting and polytunnels.
PV installations reduce the need for irrigation by providing shade
In remote, off-grid areas, agrivoltaic power can be used to supply and treat water, while also reducing the crops' need for water through shading. This counteracts the trend toward desertification and soil degradation. The world's largest agrivoltaics installation has been built on the edge of the Gobi desert in China, where berries are being cultivated underneath solar modules with an output of 700 MW. A preliminary study by Fraunhofer ISE at a site in the Indian state of Maharasthra showed that shading provided by agrivoltaic installations and the associated reduction in evaporation can boost tomato and cotton yields by up to 40 percent.
A number of challenges stand in the way of widespread use of agrivoltaics, including higher investment costs in comparison to conventional free-standing PV installations due to the support systems used for the modules as well as the need for site-specific system design. However, according to Fraunhofer ISE's October 2020 guideline on the opportunities agrivoltaics opens up for agriculture and the energy transition, agrivoltaics is already competitive with other renewable energy sources today. At seven to twelve euro cents per kWh, agrivoltaics offers levelized electricity production costs that currently remain higher than those of traditional free-standing installations, but are already below those of small rooftop PV systems.
Free-standing installations provide a valuable habitat for flora and fauna
Conventional free-standing photovoltaic installations can also provide a valuable habitat for flora and fauna. Extensive care provides protection to nutrient-poor soils, creating important biotopes for plants and insects, which in turn increases the availability of food for birds and bats. The interest group Triesdorfer Biodiversitätsstrategie - Biodiversität auf PV-Freiflächenanlagen (Triesdorf Biodiversity Strategy - Biodiversity on Free-Standing PV Installations), was recently founded to promote biodiversity in solar parks and with it public acceptance of these installations and the energy transition as a whole. In addition, the German Federal Environmental Foundation (DBU) is currently having certification standards developed for evaluating the product quality of renewably produced electricity with regard to environmental and social criteria.
Agrivoltaics at Intersolar Europe and its accompanying conference
Visit Intersolar Europe from July 21 to 23, 2021, at Messe München to learn more about developments, products and applications in the areas of photovoltaics solar thermal technologies, solar power plants, grid infrastructure and solutions for the integration of renewable energies. Manufacturers, suppliers, distributors and service providers will all gather at the solar industry's most important meeting point to present their products and innovations. At the accompanying Intersolar Europe Conference, experts will be on hand to shed light on innovative concepts and the associated technologies as well as previous experiences and future prospects as part of the sessions "Agrivoltaics: Harvesting the Sun While Cultivating Crops and Vertical Farming" and "Renewables: The Nexus of Water, Energy, and Food." This year, Intersolar Europe is also providing support for the international AgriVoltaics2021 conference for the first time, emphasizing the importance of this topic. The online event will be held from June 14 to 16, 2021, and is geared toward anyone who is interested in gaining deeper insight into the world of agrivoltaics.

Intersolar Europe is the world's leading exhibition for the solar industry, taking place annually at Messe München in Munich, Germany. Under the motto "Connecting solar business," it brings together people and companies from around the world with the aim of increasing the share of solar power in our energy supply.
Intersolar Europe focuses on photovoltaics, solar thermal technologies, solar power plants, grid infrastructure, and solutions for the integration of renewable energies. Since being founded, it has become the most important industry meeting point for manufacturers, suppliers, distributors, and service providers in the global solar industry.
