Track for waterproof solar photovoltaic bracket

The utility model relates to a waterproof track for a solar photovoltaic support, which is characterized in that the bottoms of the two sides of the track horizontally extend outwards to form extending parts, the end parts of the outer sides of the extending parts are obliquely and upwards provided with side plates outwards, the extending parts and the side plates form a water guide groove, and the tops of the side plates extend inwards to form water guide plates; a first sliding groove is formed in the upper surface of the rail in the length direction, and a second sliding groove is formed inthe lower surface of the rail in the length direction. Lightening holes penetrating through the two ends of the rails are formed in the lower portions of the end side faces of the rails. According tothe waterproof track for the solar photovoltaic support, the amount of received rainwater is large, rainwater in the external environment can be effectively prevented from damaging a solar cell panel, and the service life of
