Pressing block and roof photovoltaic system comprising same

Abstract

The invention discloses a pressing block and a roof photovoltaic system comprising the same. The pressing block comprises a pressing plate and two side plates arranged on two opposite sides of the pressing plate; the two side plates are abutted against the same surface of the pressing plate, and a clamping groove is formed by the pressing plate and the two side plates in a surrounding mode; the outer side wall on one side, far away from the clamping groove, of the side plate is provided with a pressing piece used for pressing a photovoltaic module; the outer side wall on one side, far away from the clamping groove, of the side plate is provided with a clamping part used for clamping the photovoltaic module; the pressing piece is arranged close to the bottom of the clamping groove; and theclamping part is arranged close to the opening of the clamping groove. According to the pressing block, the upper surface of the photovoltaic module does not need to be perforated and damaged, so thata water leakage phenomenon is avoided, and the phenomenon that the photovoltaic module breaks down due to rainwater entering caused by the perforation is avoided; and the construction cost and the later maintenance cost are lowered, firmness and reliability are achieved, and the wind resistance is excellent.

Description

technical field [0001] The invention relates to the field of roof photovoltaic technology, in particular to a compact and a roof photovoltaic system comprising the same. Background technique [0002] In modern society, people's pursuit of a comfortable building environment is getting higher and higher, which leads to the increasing energy consumption of building heating and air conditioning. In developed countries, building energy consumption has accounted for 30% to 40% of the country's total energy consumption, which has formed a certain restrictive effect on economic development. Therefore, Building Integrated Photovoltaic (BIPV, Building Integrated PV (Photovoltaic)) came into being. [0003] The photovoltaic modules in the existing rooftop photovoltaic system are generally fixed on the roof of the building by screws, but when installing the photovoltaic module on the roof of the building, due to processing errors or substandard construction, water leakage is prone to o...
