Agrivoltaic combines crop planting and electricity generation on the same land, it is considered as an opportunity to resolve competition for land use between food energy production. In addition growing crops, farmers can gain with installation of agrivoltaic systems their farmland. They this clean agricultural production or sell extra income. The Chinese government considers important strategy “Targeted Poverty Alleviation”. However, current methods provide uneven low irradiance which...

The imbalance between precipitation and water evaporation has caused crop yield reduction, drought, desertification. Furthermore, most parts of the world are short water, including China. We proposed a low-cost polymer multilayer film to reduce by only passing through several sunlight wavelengths necessary for photosynthesis. A series experiments were conducted characterize influence partial on reduction evaporation. Evaporation containers pans placed in open-air (CK), under glass shed (GS),...

Agrivoltaics (AV) offers a promising solution to address both food and energy crises. However, crop growth under photovoltaic (PV) conditions faces substantial challenges due insufficient light transmission. We propose large-scale cost-effective spectral separated concentrated agricultural (SCAPV) system. The system utilizes concentrator modules, cell components, dual-axis tracking systems enhance power conversion efficiency (PCE), achieving maximum PCE of 11.6%. After three years successful...

Agricultural Photovoltaic (APV) has become more popular worldwide. Its core idea is to generate electricity and grow crops simultaneously on the same farmland. We developed two APV, Spectrum Splitting Concentrated APV (SCAPV) Even-lighting (EAPV). Our previous studies have investigated generation, enhanced growth of plants/crops, reduced water evaporation Furthermore, SCAPV EAPV examined better quality increased yield many plants, such as lettuce cucumber. However, effects sweet potato not...

In agrivoltaic (APV), photovoltaic (PV) panels are positioned above farmland to produce energy and food simultaneously. However, PV block most sunlight from reaching plants for photosynthesis. Plants require We proposed Spectrum-splitting Concentrated APV (SCAPV) address contradictions between photosynthesis production This study examines the effect of SCAPV on evapotranspiration growth peanuts soybeans. Peanuts soybeans were planted under open-air (CK) treatments, a weather station was...

Light is essential for plant growth, affecting morphology and physiology. Photovoltaic agriculture (APV) was proposed in the early 80s, but generating electricity on farm field without influencing growth of crops has been a challenge researchers. In this paper, we newly designed improved photovoltaic system which can solve problem optically. Using refraction from groove glass plates, APV provides appropriate light intensity uniform illumination. We plate by calculation simulation. To...

Light-emitting diodes (LEDs) are the 4th plant supplemental lighting source. Pulsed is benefit to increase energy utilization efficiency in greenhouse production. A pulsed-lighting LED luminaire with geometrical optical solution proposed overcome shortcoming pulse width modulation (PWM) solution. In addition, this also achieves uniform by designing surfaces. illumination area, frequency 117.6 Hz and illuminance uniformity 0.789, which better than 0.75 (+/- 12.5%). an actual planting...
