After publishing the agronomic ends in viticulture and arboriculture, the French agrivoltaic specialist Solar’Agri at present 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 12 months after commissioning, the primary outcomes present the next yield beneath the panels in comparison with a reference space with out modules. Greater than 800 kilos of greens have been harvested beneath the gadget in comparison with about 500 kilos for the reference space. As well as, the eggplants harvested beneath 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,” stated Cécile Magherini, director of Solar’Agri. “Past being a instrument for adaptation and resilience within the face of local weather challenges for the farmer, the clever administration of our expertise makes it potential to optimize agricultural manufacturing.”
The crew geared up the crops with three kinds of sensors for an in depth evaluation of their situation and considering meteorological components. Micro-meteorological sensors positioned at varied plant heights measure air temperature, humidity, wind, and radiation.
As well as, Photosynthetically Energetic Radiation (PAR) sensors measure energetic radiation for photosynthesis, making it potential to estimate plant development and its wants utilizing fashions. “Plant sensors” make it potential to look at plant habits (water standing, perform, stress, organ temperature) and to optimize its profit in actual time.
“We plant totally different greens beneath these louvers with out having to whiten the greenhouses in the summertime. In two years of remark, there may be much less strain from pests resembling aphids. The longer term harvests will enable us to verify and full the primary encouraging outcomes of this gadget,” stated Youp Brinkhoff, farm supervisor.
For the reason that greenhouse was commissioned, 9 vegatables and fruits have been grown: tomatoes, cucumbers, eggplant, peppers, celery, fennel, spinach, lamb’s lettuce and inexperienced beans.
