A solar cell louver assembly includes: a plurality of solar cell module units having a solar cell panel part, with a pair of terminal portions provided on both end parts, a pair of first electrode terminals electrically connected to the respective terminal portions, and a pair of first caps mounted on the solar cell panel part to surround the respective first electrode terminals; second electrode terminals electrically connected to the first electrode terminals, and second caps accommodating the second electrode terminals and having mounted thereon the first caps; a frame unit having an inner frame such that the second caps are mounted rotatably in the length direction, and an outer frame surrounding the inner frame; and a connector unit between the inner and outer frames and having a pair of third electrode terminals electrically connecting the second electrode terminals of adjacent module units when mounted in the frame unit.

Described is a louver having a frame that forms an enclosure defining an opening, and a plurality of louver blades disposed within the opening. Each of the plurality of louver blades include a catch member that longitudinally extends between a first blade end and a second blade end of a corresponding louver blade. The louver may also include a rotation assembly configured to rotatably couple with the plurality of louver blades and the frame. The plurality of louver blades may autonomously rotate about rotation members of the rotation assembly based on environmental elements captured in the catch member such that the plurality of louver blades are configured in an open position in response to no water in the catch member and are configured in a closed position in response to an amount of environmental elements in the catch member.

The invention discloses an unidirectionally swinging linkage shutter, a roof with the shutter and a louver blade. The shutter includes a frame and a louver blade, the frame includes a longitudinal keel, the longitudinal keel includes longitudinal keel body and a positioning bar, a pin hole is defined on the positioning bar and beyond the wall, one end of the louver blade close to the indoor is hinged on the pin hole via a pin shaft, the louver blade includes a protruding section protruding outward, a linkage connection position is defined on the protruding section. The roof with the shutter includes a transverse roof beam, a longitudinal roof beam and a louver blade, the longitudinal keel includes a longitudinal keel body and a positioning bar, the positioning bar is provided with a pin hole. The structure of the louver blade is the same as above. In the present invention, the linkage bar will not interfere after the louver blades are closed, and the sealing performance is good, and the water and wind shielding effects of the louver blades are good; it is convenient to install and disassemble the louver blades on site, and can avoid the arbitrary removal of the louver blades from the outside.
