PHOTOGALVANIC INSTALLATION ELECTRIC CONNECTION DEVICE Russian patent published in 2019 - IPC H02S20/25 H02S40/34 E04D13/18 

FIELD: construction.

SUBSTANCE: group of inventions relates to an external facing panel of a building, a roofing coating, an electric connection unit for an external facing panel of a building, sets for connection with a converter of panels equipped with a photovoltaic device, an electrical device. External facing panel of building contains: upper transverse edge containing upper overlapping area, made with possibility to be overlapped by adjacent panel; a lower transverse edge comprising a lower overlapping area configured to overlap the adjacent panel; central part connecting transverse edges covered by at least one pair of columns of photovoltaic modules, each column includes an electric pole on one of its longitudinal ends and an electric pole of opposite polarity at the other end, and poles of two adjacent columns have opposite polarity; a slot in the lower overlapping area, through which the conductive tape passes, connecting one of the two electric poles of the photovoltaic module column to one of the two housings of the connecting unit, located on the back side of the panel in the lower overlapping area; a recess located in the upper overlapping area, in which the other of the two housings of the connecting unit is located, connected to the other electric pole of the photovoltaic module column. Connecting unit comprises first and second bodies configured to fit into each other. First housing comprises: a bottom comprising a hole, above which there is a sealing chamber, a side wall surrounding the bottom extending perpendicular to this bottom, with a detachable hatch for wire laying, an electric terminal connected to the bottom, the axis of which passes perpendicular to the bottom. Second housing comprises: bottom, sidewall surrounding bottom and extending perpendicular to said bottom, with wire passage, electric terminal with polarity opposite to polarity of electrical terminal of first housing. Electric terminal has an axis perpendicular to the bottom, is connected to the bottom and is located so that it is opposite to the electric terminal of the first housing, when the first and the second housings are inserted into each other.

EFFECT: technical result is easier assembly of panels and wire connection of photovoltaic modules.
