Greenhouses are crucial facilities for agricultural production. The efficiency of solar energy utilization can be enhanced by integrating photovoltaic panels (PV panels) into greenhouses as a type of agricultural photovoltaic (APV) system. An Intelligent Light-Management Photovoltaic Greenhouse (LMPG) system is proposed to overcome the shortcoming with low solar energy utilization and uneven solar irradiation distribution. This system consists of flexible PV panels, even-sunlight plates (ES plates) and light-emitting diodes (LED) luminaires. The core principle of the LMPG is “wavelength conversion and time transfer”, which can improve the lighting condition for crops in a whole day. In an actual planting experiment of lettuce and pepper, the average fresh weight of the lettuce under PV panels with supplemental lighting was 98.1% of that under normal plastic film, and the average fresh weight of the pepper under PV panels with supplemental lighting was 30.2% higher than that under normal plastic film.
