Abstract: The present invention relates to a roof rack assembly and a hood light-blocking fabric assembly, the hood light-blocking fabric assembly capable of photovoltaic generation comprising: a lower photovoltaic generation plate fixedly installed to cover the hood of a vehicle and configured to prevent inflow of heat energy of sunlight into the vehicle, to absorb sunlight, and to produce electricity accordingly; and an upper photovoltaic generation plate installed on an upper portion of the lower photovoltaic generation plate and configured to change between a first position at which the upper photovoltaic generation plate overlaps the upper portion of the lower photovoltaic generation plate and a second position at which the upper photovoltaic generation plate covers a front glass of the vehicle.

Abstract: The present invention relates to a roof rack assembly and a hood light-blocking fabric assembly, the roof rack assembly comprising: a pair of roof racks coupled to the roof of a vehicle; a photovoltaic generation light-blocking module coupled to be able to move forward/backward along the pair of roof racks and configured to expose/cover the roof and to block sunlight; a light-blocking plate transfer portion for applying a driving force such that the photovoltaic generation light-blocking module moves forward/backward along the pair of roof racks and is unfolded over the roof of the vehicle or is folded; a converter for converting electric energy generated by the photovoltaic generation light-blocking module into power that can be used by the light-blocking plate transfer plate and the vehicle; an accumulator for storing power converted by the converter; and a controller for controlling supply of power by the converter and the accumulator.
