After publishing the agronomic ends in viticulture and arboriculture, the French agrivoltaic specialist Solar’Agri right now revealed a report on an eggplant plant grown within the Brinkhoff agrivoltaic greenhouse in Granges-sur-Lot, within the Lot area -et-Garonne.
Commissioned in September 2020, the 2500 m² facility responds to the operator’s must adapt manufacturing to better local weather dangers. A rise within the common temperature in greenhouses (30 C in spring and 40 C in summer season) causes burning of flowers and accelerates the event of latest pests.
One yr after commissioning, the primary outcomes present the next yield underneath the panels in comparison with a reference space with out modules. Greater than 800 kilos of greens have been harvested underneath the system in comparison with about 500 kilos for the reference space. As well as, the eggplants harvested underneath the panels have the next biomass, just like higher plant improvement.
“We’re happy that this suggestions from the Brinkhoff greenhouse confirms the sphere of advantages of dynamic agrivoltaics for market cultivation and greenhouse crops,” mentioned Cécile Magherini, director of Solar’Agri. “Past being a device for adaptation and resilience within the face of local weather challenges for the farmer, the clever administration of our know-how makes it doable to optimize agricultural manufacturing.”
The group outfitted the vegetation with three varieties of sensors for an in depth evaluation of their situation and bearing in mind meteorological components. Micro-meteorological sensors positioned at numerous plant heights measure air temperature, humidity, wind, and radiation.
As well as, Photosynthetically Lively Radiation (PAR) sensors measure lively radiation for photosynthesis, making it doable to estimate plant progress and its wants utilizing fashions. “Plant sensors” make it doable to watch plant conduct (water standing, operate, stress, organ temperature) and to optimize its profit in actual time.
“We plant totally different greens underneath these louvers with out having to whiten the greenhouses in the summertime. In two years of statement, there’s much less stress from pests equivalent to aphids. The long run harvests will permit us to substantiate and full the primary encouraging outcomes of this system,” mentioned Youp Brinkhoff, farm supervisor.
Because the greenhouse was commissioned, 9 vegetables and fruit have been grown: tomatoes, cucumbers, eggplant, peppers, celery, fennel, spinach, lamb’s lettuce and inexperienced beans.
