A greenhouse roof with an adjustable reflective film

Abstract

This utility model discloses a greenhouse roof with an adjustable reflective film, comprising multiple spaced pillars, with multiple roofs positioned between the tops of adjacent pillars. Each roof is composed of photovoltaic modules and a light-transmitting film. A reflective film is installed beneath each roof, and the reflective film has three switchable states: an arc shape, a straight shape, and a folded V-shape. In this application, when plants need sunlight, the reflective film is folded into a V-shape; when more sunlight is needed for power generation, the reflective film is unfolded into a near-arc, catenary-like shape; and during strong winds, the reflective film is straightened to prevent wind damage.
