Analysis of Photovoltaic Agriculture Model Based on the Single Axis Tracking System

摘要

Due to the shading of PV panels, the normal growth of high-illumination-loving plants can not be met, only low-illumination-loving plants are planted in the greenhouse. Aiming at improving this phenomenon, this paper analyzes the characteristics of light demand of the plants, and reveals the principle of agricultural photovoltaic complementary by using the characteristics of light saturation. On this basis, the paper combines with the technical characteristics of the single axis tracking photovoltaic system, according to the light conditions to optimize the photovoltaic angle, to change the light characteristics of the greenhouse, so as to solve the coupling problem between agriculture and photovoltaic. Finally, this paper gives an optimization analysis by taking a 50kW photovoltaic greenhouse as an application scenario. The result shows that 31% improvement of the comprehensive benefits are achieved, which proves that the method in this paper is feasible.
