Description

[Detailed Description of the Invention] This invention relates to a roof covered with a solar cell roof panel in which solar cells are arranged in the panel.

Generally, currently used solar cells (for example, silicon single-crystal type) tend to reduce their power generation efficiency when exposed to high temperatures, so it is necessary to take some measures against high temperatures even on roofs equipped with solar cells.

This project provides a roof equipped with solar cells that can maintain the solar energy conversion efficiency of the solar cells and collect and utilize surplus or by-product thermal energy. An airflow passage is formed extending from the opening to the outside air provided in the ridge part through the back side of the solar cell roof panel to the opening to the outside air provided in the ridge part, and a heat exchanger is installed in the airflow passageway in the ridge part. It is located where it is placed. Embodiments of the present invention will be described below with reference to the drawings.

According to the roof equipped with solar cells of this invention, the solar cell roof panel is constantly cooled by the outside air flowing from the eaves side opening through the airflow passage to the ridge side opening, increasing the power generation efficiency of the solar cells. In addition to being able to maintain a good temperature, the heat energy received when air flows through the air flow path can be collected and used in the ridge using a heat exchanger, and the back side of the solar cell roof panel can be ventilated. This makes it possible to prevent dew condensation from forming on the roof panel.
