Further, drip the eaves and set up along the length direction of rubber strip, drip the one end fixed connection of eaves and set up in the one side of the transverse direction of rubber strip, its other end slope is downwards, introduces the rainwater in the water drainage tank.

Further, the rubber strip is of a hollow structure.

In the structure, the rubber strip is of a hollow structure, so that the rubber strip can be closely attached to the back of the photovoltaic module, and the sealing performance of the rubber strip is improved.

Further, rubber strip is inside to be equipped with first hollow portion and the hollow portion of second along its length direction, the hollow portion of second is located one side of keeping away from water drainage tank of first hollow portion, makes two rubber strips on water drainage tank both sides be the splayed and arranges.

Due to the adoption of the structure, the sealing effect of the rubber strip can be increased, and rainwater is prevented from moving along the back of the photovoltaic module and entering the house.

Furthermore, the lower part of the rubber strip is provided with a bulge along the length direction, and the bulge is embedded in a groove at the edge of the drainage groove in a matching manner.

Due to the adoption of the structure, the rubber strip can be connected to the edge of the drainage groove, the position of the rubber strip is prevented from deviating, the sealing effect of the rubber strip is ensured, the working steps of a construction site can be reduced, and the installation efficiency is improved.

Further, the rubber strip is made of silicon rubber.

In the structure, the silicon rubber belongs to inorganic rubber, has certain flame retardance, and can prevent fire from spreading when a house is in fire.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:

the utility model discloses in, the rubber strip is located between photovoltaic module's the limit portion and the trough of water drainage tank's groove limit for sealed between the two, inside the rainwater of avoiding by the infiltration of photovoltaic module joint gets into the house between photovoltaic module's the limit portion and the trough of water drainage tank's groove limit, one side of the horizontal direction of rubber strip is equipped with drips the eaves simultaneously, drips the eaves will be by inside the rainwater introduction water drainage tank of photovoltaic module joint infiltration, can effectual solution house problem of leaking.
