The utility model relates to photovoltaic technology field, concretely relates to a kind of building photovoltaic integrated system, including connecting mechanism and drainage mechanism, connecting mechanism is used to connect each photovoltaic module into photovoltaic row group in transverse direction, drainage mechanism is connected between the upper and lower two rows of photovoltaic row group, the interval of the two rows of photovoltaic row group is 0.5-5cm;The connecting mechanism includes the clamping piece of I-shaped, clamping piece includes detachably connected upper clamping plate and lower clamping plate, the drainage mechanism includes drainage assembly, drainage assembly is provided with water guide groove along its axial direction, the two side edges of drainage assembly are respectively installed in the lower surface of upper photovoltaic row group and the upper surface of lower photovoltaic row group. By implementing the present application, the waterproof effect of photovoltaic roof is improved.

The application discloses a photovoltaic module temperature control system, which is configured to be connected to a photovoltaic panel, the photovoltaic panel has a light-receiving surface and a back surface, and the photovoltaic module temperature control system comprises a frame body and a temperature control assembly. The frame body is provided with a through groove for nesting the back surface of the photovoltaic panel. The temperature control assembly comprises a plurality of temperature control pieces which are arranged at intervals and are distributed in an array along the surface of the back surface of the photovoltaic panel. The temperature control piece comprises a phase change energy storage part which is configured to be connected to the photovoltaic panel and abuts against the back surface of the photovoltaic panel, so that the temperature of the photovoltaic panel can be maintained within a preset temperature range. The application can effectively solve the problem that a person needs to clean the snow and ice on the photovoltaic panel after the photovoltaic panel is covered with snow or ice under cold conditions.
