The present invention relates to a roof-integrated photovoltaic system installed on a roof support structure to form a roof of a building structure.

Recently, interest in solar power generation as an alternative energy source according to the depletion of resources is increasing. Solar power generation is an integrated technology that converts sunlight incident on the earth into electrical energy. Not only is it eco-friendly, but once the device is installed and operated, even if there is no separate energy input, it can produce electricity if only sunlight exists. There is a trend that the scope of its application is gradually expanding.

In general, photovoltaic power generation is a unit photovoltaic module (photovoltanic module) consisting of a plurality of solar cells, a wire electrically connecting the solar cells, and a film or protective glass that protects the solar cells from the external environment in series. Alternatively, it is operated using a solar panel configured by connecting in parallel. In order to apply such a solar panel to a building, the most commonly used method from the past to the present is a method of mounting a solar panel on the roof of an existing building.

This method has the advantage that there is no need to dismantle an existing building or construct a new structure for the installation of a solar panel in that it can be implemented by simply fixing the solar panel to the roof. However, this method has a disadvantage in that the appearance of the building deteriorates in that the solar panel is installed on the roof of the existing building.
