Photovoltaics on moorland sites – SUNfarming presents pilot plant

SUNfarming presents pilot plant at Hof Hanken, Elsfleth. More than 60 interested farmers, representatives of local authorities, planners and members of various associations interested in the expansion of renewable energies on agricultural land accepted the invitation of the Grünlandzentrum Niedersachsen/ Bremen e.V. from Ovelgönne to a lecture event on the topic of PV on agricultural land in the Innovative Landwirtschaft Ostfriesland (ILO) project on 25 October.

Under the moderation of Simon Schoon, Project Manager of the Grassland Centre Lower Saxony/Bremen e.V., SUNfarming Managing Director Edith Brasche presented the SUNfarming Agri and Moor PV concepts and solutions for the sustainable agricultural use of grassland and moorland. Helmut Wahl, energy technology consultant at the Lower Saxony Chamber of Agriculture, provided information on the legal and tax framework for agri-PV compared to traditional ground-mounted PV systems. Questions relating to the realisation and approval of corresponding agri-PV and moorland PV solutions were discussed during the open discussion round. During the subsequent visit to Hof Hanken in Elsfleth, farmer Dirk Hanken reported on how well the SUNfarming moorland PV pilot system had been received by his cattle on the moorland grazing area. It is particularly noticeable that the sward under the modules is completely covered with grass.

Lena Weber and Dr Dina Hamidi from the University of Göttingen presented initial scientific findings from animal husbandry under agri-PV on peatland. In the concluding survey, many of the interested visitors stated that they would like to develop specific agri-PV or peatland PV projects on their land and enquired about lease payments and participation models for specific projects from SUNfarming Managing Director Edith Brasche and Project Manager Lower Saxony Thomas Reimers.

All interested parties are also cordially invited to SUNfarming's research and development centre in Rathenow near Berlin, Am Heidefeld 13, where the company will be presenting all types of agri- and peatland PV with crop cultivation and animal husbandry in detail. For appointment enquiries, please contact e.brasche(at)sunfarming.de.

State Secretary visits SUNfarming Agri-Solar Centre Rathenow

Gert Zender, State Secretary in the Ministry of Economics, Tourism, Agriculture and Forestry of Saxony-Anhalt, accompanied by Volker Rost, Head of the Agricultural and Rural Areas Department, and Chris Schulenburg, CDU Member of the State Parliament, visited the SUNfarming Agri-Solar Research and Innovation Centre in Rathenow at the invitation of Christian Knees and Peter Schrum. The government delegation was visibly impressed by the status of the finished series production of the SUNfarming Agri-Solar Din Spec systems.

The politicians were impressed by the fact that SUNfarming Agri-Solar systems, with a maximum height of just 3.6 metres, can be used for agricultural purposes with small tractors, which can be replaced by AI Agri Robotic in the future and blend in well with the landscape. They also praised the patented SUNfarming rainwater distribution system for extensive irrigation under the modules.

In addition to the tour of the plant, the following topics were addressed at the meeting:

- Solar open spaces are currently still 100% the responsibility of the Minister of Energy/Environment. Farmers and SUNfarming are calling for the Ministry of Agriculture to be given a say in authorisations for agri-solar systems.
- Another demand is that agri-solar must be eligible for authorisation in landscape conservation areas, as is already the case in other federal states, due to the agricultural production that is possible here.
- In view of the fact that set-asides (CAP 4-10% fallow land) can also be combined with agri-solar in the future, this will also lead to landscape conservation areas and sites with better soils being opened up for agri-PV in Saxony-Anhalt.
- In the opinion of SUNfarming, it is incomprehensible why land utilisation plans are still necessary for agricultural agri-solar systems. As agri-solar is still an agricultural use, it should not be treated as a purely open-space system, explains Peter Schrum, SUNfarming founder.


Village power concepts and school gardens:

To further increase acceptance significantly, SUNfarming already has regional village electricity concepts where the community receives cheaper electricity. The village electricity concept was also very well received. Just like the SUNfarming school garden, which is made available to the community in municipalities with agri-solar areas of 50 ha or more for joint use to grow vegetables, fruit or for poultry farming, for schools and kindergartens to teach healthy eating.

SUNfarming flowering mixture for biodiversity PV

At the SUNfarming Research and Development Centre in Rathenow, Germany, a flowering mixture specially composed for us was sown under our solar panels with rainwater distribution this summer. This has developed healthily with a good water supply.

Under GAEC 8 (Healthy Agricultural Ecological Status), a set-aside area may only be grazed or mown in September. For this agricultural policy SUNfarming combines flowering meadows with agriphotovoltaics.
Over 40 different wildflower seeds are contained in the special mixture. Among them are various types of clover, meadow bluebell, viper's bugloss, corn poppy, true parsnip and meadow sage. The wildflower component in the SUNfarming mix is REWISA certified (Regional Wild Plant Seeds). Various grasses in the mixture increase forage quality and grazing suitability. They improve soil structure, suppress weeds and provide adaptation to dry or wet soil.

For biodiversity areas with natural species diversity, Agri-Photovoltaic plants are suitable, which are approx. 2.1m at the lowest edge. In general, sown wild herbs should reproduce themselves by seed. Cutting or mulching should therefore only take place after the seeds have set or not at all.

Due to the shading and the resulting cooler climate, evaporation under the panels is considerably reduced. Even between the rows of panels, the shadows cast by the module table counteract drying out. Under the panels, flowering plants develop more in the second year of standing and can flower for a very long time. The rainwater distribution technique has a positive effect; in this area, plants thrive better on light soil.

"From my point of view, it is worthwhile under Agri-PV systems to use a very versatile mix that can adapt to the environment (different shading, different soil, different climate depending on the location even within the system). Not only single grasses/flowering plants should be used. Drought-tolerant plants can be used as well as moisture-loving ones," explains Michael Bleiker, SUNfarming project manager at the Rathenow Research and Innovation Centre.

The wildflower mix produced for SUNfarming can now also be purchased under the trade name SUNfarming B1 from „Samen Schwarzenberger“.

Huge demand for SUNfarming Agri-PV solutions at Eurotier

The world's leading trade fair for professional animal husbandry and livestock management as well as the leading trade fair for decentralised energies, Energy Decentral, took place in Hanover from 15 to 18 November. SUNfarming was present in the Energy Decentral area with a large stand and showed its latest Agri-PV animal welfare system as well as the SUNfarming "Umbrella", which was specially developed for use on apple, pear and cherry orchards and in viticulture.

Several thousand farmers from Germany, but also from countries such as Poland, Hungary, Switzerland, Austria, Canada and the USA - came to the SUNfarming stand to find out about Agri-PV solutions for both animals and special crops. More than 1,000 hectares of potential Agri-Solar areas were included in the early SUNfarming planning in Germany.

For more than 10 years, SUNfarming has been developing Agri-PV solutions with glass-glass modules and rainwater distribution system under the modules with its own engineers and has been researching them for many years in different developing countries of the world under extreme climatic conditions as well as with different types of plants. Due to the climate changes as well as the energy crisis in Germany, farmers from all over Germany and neighbouring countries were very interested in the SUNfarming solutions. They were particularly enthusiastic about the well thought-out solution for keeping animals on pastures protected by Agri-PV all year round.

Due to the rainwater separation and the semi-transparent modules, which allow approx. 15 % light to pass through, plant growth is ensured under the modules, CO2 remains in the soil due to the areal moisture distribution. The agricultural status of the land is maintained with SUNfarming Agri-PV. As a partner of the farmer, SUNfarming places particular emphasis on the agricultural concept, which is developed together with the farmer and his agricultural advisor. SUNfarming Agri-PV is ideally suited for areas with low soil points as well as arable land for special crops (fruit/vegetables) and for animal welfare-oriented livestock farming, as well as for moorland that is to be re-wetted.

SUNfarming invests in 2.3 hectares of solar power area for Pirmasens

It will be the largest freefield photovoltaic plant within the boundaries of the city of Pirmasens.

As a contribution to the energy turnaround and energy supply with green photovoltaic electricity, SUNfarming is realising a photovoltaic plant on the 9-hectare site of the Ohmbach household waste landfill, which has been closed since 1 February 2022. With a module area of over 2.3 hectares, this is the largest open-space photovoltaic plant within the boundaries of the city of Pirmasens.
Andreas Flörchinger, Head of SUNfarming Project Development: "I am very pleased to be able to implement this project in my former home region of Palatinate, together with Ralf Gebhard, Head of SUNfarming South-West. The PV plant, which has been under construction since October 2022, offers an opportunity to create an additional use with added value for the environment and society on an ecologically damaged landfill site. The photovoltaic plant on the landfill site is scheduled for completion by March 2023. We at SUNfarming would like to express our gratitude for the very good cooperation with the city of Pirmasens."

Some facts about the plant:
- 2,470 t CO2 savings per year due to the photovoltaic plant Landfill Ohmbachtal, Pirmasens.
- 823 cars can offset their CO2 emissions with 20,000 km/year of driving or
- 2000 households can be supplied with 2,500 kWh/year of CO2-neutral PV electricity.
- Grid feed-in: approx. 5,083,440 kWh/year
