Swedish researchers measured the yield of barney in a vertical agrivoltaic facility and located that regardless of the shade created by the modules the yields have been comparable to regulate circumstances within the open discipline, if not much less. excessive. Their methodology will be replicated for different websites and crops.
Researchers at Mälardalen University in Sweden are investigating the consequences of a vertical agrivoltaic (APV) system on barley yield and nutrient content material in Sweden throughout the 2023 rising season.
“The dataset exhibits that barley grown underneath the vertical APV system has comparable yields to open-field management circumstances regardless of elevated shading as a result of vertical panels,” the lead creator of the analysis, Silvia Ma Lu, mentioned. pv journal. “The dataset consists of particulars on kernel and straw yield, protein content material, and starch ranges, together with climate and photo voltaic irradiance information from the rising season.”
“The The 2023 summer time is marked by contrasting extremes with dry and scorching climate in June, and heavy rains in July and August.” co-author, Pietro Campana, added. “More particularly, it was noticed that the imply yield of barley in all of the totally different areas of the vertical agrivoltaic system was larger than the one within the management space, however not statistically important.
The scientists carried out their evaluation in a vertical agrivoltaic facility situated in Kärrbo Prästgård, close to Västerås, Sweden. For their evaluation of barley yield, they thought-about parameters corresponding to nitrogen content material, crude protein stage, kernel yield, straw yield, starch content material of kernels, and thousand kernel weight (TKW). The outcomes are in contrast with these of a reference plot and not using a PV system.
The samples have been taken by hand 5 centimeters from the bottom on September 7, 2023, with every pattern equivalent to a sq. space of 0.25 m.2. The recent weight of the samples was measured instantly after reducing. Afterwards, the samples have been dried at 60 C for twenty-four hours and reweighed to find out the dry matter (DM) content material.
“Grain and straw yields have been calculated accordingly,” the researchers defined. “An roughly equal quantity of water content material in grains and reducing straws is assumed.”
The group mentioned the proposed methodology could possibly be replicated for different websites and crops.
Their findings are introduced within the paper “Data on the consequences of a vertical agrivoltaic system on crop yield and nutrient content material of barley (Bardeum vulgare L.) in Sweden,” revealed in Data in Brief. “The findings help additional analysis on the APV system, for instance, for plant mannequin validation. They additionally encourage collaboration by sharing discipline experiment information,” mentioned Ma Lu.
Another analysis group at Mälardalen University has just lately developed an algorithm to optimize the electrical energy yield of agrivoltaic installations with vertically mounted bifacial PV modules.
Other researchers on the similar college have developed a way for figuring out and classifying appropriate areas for the set up of agrivoltaic programs.
