Photovoltaic roof and construction method thereof

The invention relates to a photovoltaic roof which comprises a roof panel and a photovoltaic panel installed on the top of the roof panel. The photovoltaic roof is characterized in that the roof panel is provided with a sunken part, the photovoltaic panel is arranged above the sunken part in a crossing mode, and a heat dissipation cavity is formed between the bottom of the photovoltaic panel and the roof panel. According to the photovoltaic roof, the photovoltaic panel is installed on the roof panel top, meanwhile, the sunken part is reserved to enable the photovoltaic panel to dissipate heat, better heat dissipation performance is achieved, and the power generation efficiency of the photovoltaic panel is improved. 本发明涉及一种光伏屋面，包括屋面板和安装在屋面板顶部的光伏面板；其特征在于，屋面板具有凹陷处，光伏面板跨设于凹陷处上方，使光伏面板的底部与屋面板之间形成散热空腔。本发明的光伏屋面在将光伏面板安装于屋面板顶的同时，还留有凹陷处使光伏面板散热，具有更好的散热性能，提高了光伏面板的发电效率。
