Abstract

A hybrid photovoltaic/illumination rooftop module is proposed for greenhouse environmental control. The design counterbalances seasonal irradiance and temperature extremes while simultaneously generating renewable energy. Oneaxis tracking is used to increase photovoltaic collection. The tracking system also provides a seasonal variation of shading and ventilation to control temperature in the greenhouse. A faceted illumination structure is added to the module, which modifies irradiance by changing the solar angle. Irradiance in the greenhouse is simulated throughout the year for a particular site latitude and facet angle. Adjustments in the design can be made to customize the rooftop for a specific site location, illumination range, and irradiance uniformity.
