Abstract Integration of photovoltaic modules into greenhouse roofs is a novel and intriguing method. The cost products grown in greenhouses particularly high because their energy consumption for heating cooling, at the same time increase demand available land, increasing its creating spatial issues, integration photovoltaics on roof highly viable solution. Simultaneously, use solar radiation critical to maintain optimal crop development, while also being renewable source. However, reduce incoming greenhouse, due shade. Shading can be either beneficial crops or not, depending type, thus it vital find shading caused by both temporally spatially. In this study, model calculating roof-integrated developed, based Sun position, geometry position roof. Calculating coefficient variation data, shaded unshaded areas using proposed algorithm, was found lower than that least 76% time. Also, values under area are more uniform. tool PV designers, operators, owners, order optimize potential panel installations.
