(Erkner/Berlin, 30 August 2018) On the sun terrace of the Estrel in Berlin, the largest hotel in Europe, SUNfarming has built its solar greenhouse at a height of 50 m. The greenhouse, which is covered by a 4 m wide light dome, has a size of approx. 42, 5m ² (5m x 8, 5m). The rooftops east and west of the light dome are equipped with SUNfarming modules, the generated solar power is used directly by the hotel.
The plant is used by SUNfarming GmbH as a model of larger SF Food & Energy plants and SF Urban Farming in Germany in order to present project partners, politicians and financial partners, including ambassadors from African States, SF Food & Energy in a practical manner. Under the partial shading of the greenhouse, a micro-climate with low evaporation is formed; This favours the growth of different types of vegetables as hydroponics. Irrigation is carried out by means of a water-saving drip irrigation. This makes it possible to cultivate plants at otherwise barren sites – such as house roofs or in resource-poor areas (crisis regions, developing countries).
Kitchen director Peter Griebel harvests fresh and regional organic vegetables and herbs for his restaurant kitchens. At present, tomatoes, zucchini, cucumbers, blueberries, chilies, bavarian figs and medicinal herbs are mainly harvested here.
On August 29th the project was inaugurated during the course of a rooftop party. Numerous guests from politics and business had followed the joint invitation of SUNfarming and Estrel and had the opportunity to visit the solar greenhouse, accompanied by specialized experts who were happy to answer all the questions.
In his opening speech, hotel director Thomas Brückner highlights the great interest of the Estrel hotel in healthy organic food products and its own spice production in cooperation with SUNfarming.
In his address, Peter Schrum,the main shareholder and founder of the SUNfarming Group, emphasizes the wide range of possible applications and possibilities for development policy: “The advantages for citizens and municipalities are endless. SUNfarming Urban Farming Plus contributes to the regional supply of cities. This project offers a wide participation of the municipalities with long-term ownership, sustainable food and energy production and job security with a strong training component also for schools and research institutions “.
Internationally, the SUNfarming multi-purpose light domes can make an important development policy contribution to the elimination of escape causes. With these projects, we not only save resources, but also create knowledge resources for the future through educational offerings”, concludes Peter Schrum.

We are very excited!
Our project “SUNfarming Food & Energy” was selected by an independent jury of experts among the TOP 3 finalists in the category Sustainable Development.
Since its founding in 2008, the GreenTec Awards have become the world’s most important environmental award. Together with more than 120 partners, they offer large and small companies the international stage to present the best projects for environmental protection.
SUNfarming Food & Energy:
Agro-solar greenhouses provide sustainable food, energy, jobs, education
SUNfarming´s unique technology makes it possible to produce economically attractive and resource-efficient food and energy at the same place. The project is providing knowledge transfer in train-the-trainer programmes for students and skills development for people from local communities.
15 agro-solar green-houses have been installed on the campus of the NWU University in South Africa. A team of experts from North-West University and SUNfarming is responsible for the running and training of agro-solar technologies and the research purposes to identify the right crops. The generated solar power is used directly by the university.

The first Food & Energy Training Centre in South Africa is a partnership project:
Operating project partner: North-West University Potchefstroom
Co-financing project partner: KFW DEG (Deutsche Investitions- und Entwicklungsgesellschaft mbH)
Coordinator of the project: ALENSYS (Alternative Energiesysteme AG)
The greenhouse, covered with a 4 m wide light dome, has a size of 42.5m² (5m x 8.5m). The roof tops, east and west of the light dome, are equipped with SUNfarming modules, the generated solar electricity is used directly by the hotel.
The “SF Urban Farming Concept”, developed by SUNfarming, produces sustainable solar energy and regional food – on the same place. In addition to the solar power, vegetables, fruits, flowers or fish can be gained between the modules of new or already built PV free-field plants or in special agro-solar Food & Energy greenhouses.
Here, from one of the highest points of the Estrel, Peter Griebel, the kitchen director, not only enjoys a magnificent view over Berlin, but here he is now harvesting herbs, cauliflower, chili, chard and physalis, to mention only a few. Regionally and sustainably produced finesse and highlights for the hotel kitchen.

Another SUNfarming solar park was successfully completed in Mühlenbeck in the Oberhavel region.
“Mühlenbeck” is a solar park of superlatives: on an area of 55,000 m² on the former landfill, 12,048 solar modules of the type SUNfarming SF-AT235-60P with 260 and 265 Wp power were installed. The SUNfarming quality modules and inverters used are all “Made in Germany”. The energy produced in this way of 3,229,800 kWh can supply 1,000 2-person households with clean solar power in the year. In addition, SUNfarming is contributing around 1,937.511 kg of CO2 emissions this year, which corresponds to the output of approximately 750 medium-class cars.
Up to 50 fitters and technicians have carried out a “small miracle” and rammed up to 5000 posts, sometimes up to 1.20 m deep, into the ground, 516 “tables” and the modules were mounted.
SUNfarming invests 3.5 million euros from planning to completion of the plant. The leasing contract for the landfill site is over 20 years with an extension option of 5 years.
„Thanks to the good cooperation of politics, management and the executive companies the solar park could be established in record time“, said Managing Director Martin Tauschke. This excellent teamwork was also necessary, since plants of this size will no longer be possible from 2017, according to lawmakers. The upper limit will then be 0.75 MW. 3 days before Christmas 2016 the building permission was granted.
For the building authority manager Hans-Werner Labitzki the use of the landfill site is a sensible and sustainable after-use, valuable agricultural areas are spared. Furthermore, the safety fence built around the solar system prevents the possibility that wild boars could exploit old rubbish, as happened in the past.
Mayor Fillipo Smaldino-Stattaus is also pleased with the completion of the plant:
“The municipality’s trade tax revenues are rising and the municipality is saving the costs of securing and maintaining the area. Again, a puzzle piece has been found on the way to the green community of Mühlenbecker Land “.
The use of near-natural sheep grazing as a nursing procedure complies with our ecological principles and is highly accepted by the population.
Since 2016 we have been using sheep herds to graze our solar parks in Mecklenburg-Vorpommern. A requirement for the functioning of the solar modules is the prevention of shading caused by plant growth. The regular care of the vegetation by sheep grazing prevents shading of the modules.In contrast to mechanical mowing, there is no dust development or damage caused by stone impact. The shepherd’s checks at irregular times also reduce the risk of theft.
The shepherd also benefits from this safe pasture, which is already provided with fencing. The modules are a good shade dispenser and draft shield and the substructures offer retreats for lambing sheep. The surfaces are unloaded since no fertilizers and pesticides are used.
The nature conservation association welcomes the double use of the land, the extensive grazing has positive effects on the biodiversity, through the practiced change of the pasture the sheep serve other animal and plant species as means of transport and thus increase the biodiversity. Due to the good experiences with this environmentally friendly and gentle care of the areas our sheep are now also in Falkensee in Brandenburg -the sheep seem to like it.
With the impressive output of 3.281,76 kWp the latest SUNfarming free-field plant in Wriezen is a showcase of how to produce, clean renewable energy power on a former dumpsite for municipal and industrial waste.
It can be avoided 2.012kg CO2 emissions per year.
A special engineering and technical challenges were the concreted piles for the foundation of the support structure for the solar modules. Not deeper than 60 cm were the piles framed into the restoration layer of the dumpsite.
“Our engineers and technicians completed the plant in just 3 months, including power supply, and it was successfully connected to the grid in July 2016. 12,400 SUNfarming modules AT 235-60P 265 Wp “Made in Germany “, have been installed, explains Martin Tauschke, CEO of SUNfarming.
All work has been strictly controlled by the supervision of the landfill operator. The successful acceptance successes from the State Office for the Environment in Brandenburg.
