A deployable and retractable photovoltaic awning assembly is formed from a flexible sheet of photovoltaic devices attached to a rotatable roll at one end and a boom at the other. A pair of side support tubes are provided with tracks that receive slides maintained on opposite ends of the boom. At least one of the slides is axially movable with respect to the boom, ensuring engagement of the slides in the tracks as the boom is moved away from and toward the roll during deployment and retraction of the flexible sheet. In this regard, the slides are mounted on pins through articulated joints of the spherical/universal type. The sheet of flexible voltaic devices is preferably transmissive as to light wave lengths in the range required for vegetation photosynthesis, and absorbert for all other ranges, allowing the awning to be deployed over vegetated areas, without interference with the photosynthesis process. Moreover, the awning may be retractable in periods of rain or the like, ensuring that the vegetation is properly and naturally attended.
