Various combinations of photovoltaic materials and structures were selected to test the feasibility of improving soybean yield and quality with agrivoltaics systems. It was found that 40% semi-transparent photovoltaic panels (3.2mm CDTe + 0.4mm EVA) could maintain soybean yield without reduction, with crude fat, soluble sugar and starch content .
We provide a comprehensive evaluation of the performance of traditional photovoltaic panels (monocrystalline silicon), 40 % semi-transparent photovoltaic panels (3.2 mm CDTe + 0.4mmEVA), and no photovoltaic panel treatment in soybean cultivation, including environmental factors, photosynthesis rate, phenotype and dry matter accumulation, yield .
The areas of APV facilities were 1980 m 2 for potato, 1815 m 2 for sesame, 1030–2800 m 2 for soybean, and 1180–3267 m 2 for rice. The areas of control plot for each crop were over 1000 m 2. The shading rates of the APV used in this study ranged from 25% to 32%. The panel height of the APV ranged from 4.0 to 4.5 m.
This study focuses on estimating the global area suitable for agrivoltaics (PV over crops) and rooftop PV by employing open-access data, existing literature and simple numerical methods in a.

6 FAQs about [Soybean planting under photovoltaic panels]
Which agrophotovoltaic systems are used to grow soybean?
Table 6. Growth and yield of soybean underneath agrophotovoltaic (APV) systems in Paju and Youngkwang, South Korea. Three APV facilities were used (Seungju, Boseong, and Naju) for the rice study.
Can agrivoltaics preserve cropland in a full-density PV system?
Compared to PV installations causing these croplands to be completely abandoned, agrivoltaics in a full-density PV system scenario could preserve up to 139 km 2 of cropland with a corresponding crop yield of 7.1 × 10 4 tons, which is 9 % of the crop yield in a no-PV scenario.
Do APV systems reduce soybean yields?
In two distant locations (Paju and Youngkwang), soybean crops grown underneath APV systems at both sites showed increased ungrained ratios per pod and a reduced yield of 18–20% compared to the control plot.
How do you manage vegetation under a solar array?
To date, the most common plans for vegetation management under solar arrays are mechanical control (mowing), grazing sheep, and pollinator habitat, or a combination of these three. In almost every scenario a mixture of different plant species will provide more desirable outcomes than a monoculture.
Does shade depth affect soybean yield negatively?
In this work, for the first time, a soybean crop was cultivated under a large-scale Agrivoltaic System, and the field results (morphological and physiological traits and yield) were used to validate a simulation model to forecast the soybean yield. The soybean yield was affected by the shade depth levels, as evidenced by the changes in morphological and physiological traits.
How to manage undesirable plants before a solar array is built?
In many cases management of undesirable plants will face less hurdles before the construction of the solar array. Mowing – if time permits prior to the start of construction, frequent mowing can reduce the presence of some weed species and encourage the growth of more desirable species.
