Professor Wang from the College of Agriculture and Environment of a certain university was once worried about the cross-disciplinary research experiment on photovoltaic agriculture: "We study the growth patterns of crops under photovoltaic panels and need to precisely control the light intensity and spectral composition. However, traditional simulator light emphasizes a coarse node step size (5%), and the spectrum is fixed and unadjustable, which leads to the dispersion of crop photosynthetic efficiency test data and delays the project by two years." Moreover, the operating noise of the equipment exceeds 70dB, which affects the growth environment of plants. The small light spot splicing also causes uneven lighting on the pilot platform, making it impossible to scale up the experiment.
The research customization version of Saifan's 3A-level solar simulator makes cross-disciplinary research smoother. The equipment supports continuous adjustment of light intensity with an accuracy of 0.1%, and independent control of ultraviolet, visible and near-infrared bands (with an accuracy of 1%). It can simulate the lighting environment under different light transmittance rates of photovoltaic panels, and is suitable for various scientific research scenarios such as crop growth, photocatalysis and photoelectric conversion. Adopting low-noise light source driving technology, the operating noise is ≤55dB, close to the background noise of the laboratory, and does not interfere with the growth of organisms or the operation of precision instruments.
Now we have successfully developed the optimal lighting solution for photovoltaic agriculture. Last year, we published three papers in top SCI journals and applied for four national invention patents. After the project was implemented, the income per mu increased by 2,000 yuan. Professor Wang gave a thumbs-up, saying that a single unit of the equipment can cover a 200-square-meter pilot platform, with a light uniformity of 97% and the repeatability of experimental data increased from 65% to 99%. "Through the upper computer software, the light change curve can be preset, and it can be linked with temperature, humidity, and CO₂ sensors to achieve closed-loop control. Previously, four people took turns to operate, but now one person can complete the entire process of the experiment."
