Description

Waterproof assembly of BIPV photovoltaic roof

Technical Field

The utility model relates to the technical field of photovoltaic buildings, in particular to a waterproof assembly of a BIPV photovoltaic roof.

Background

The photovoltaic roof is characterized in that a photovoltaic power generation system is arranged on the roof of a building, the principle of photovoltaic power generation is based on the photoelectric effect, direct current generated by a solar panel can be converted into alternating current by an inverter, the alternating current is regulated to 220 volts by a transformer, and the 220-volt alternating current is integrated into a power grid by a grid-connected point, so that the requirement of power supply for a user is met, and the aims of energy conservation and emission reduction are achieved. The photovoltaic building roof can be defined as two major categories, BIPV (building integrated photovoltaic) and BAPV (solar photovoltaic power generation system attached to a building) according to the installation system of the photovoltaic module. First, BIPV is a functional part of a building structure, incorporated into the design of a building, for example, to replace traditional roofing materials (tiles, windows, etc.), i.e., BIPV is both a power generation product and a building material, integrating two functions. The BAPV is an addition of a building, is not directly in functional connection with building materials, only has the function of generating electricity, and is mainly used in the current common use forms of a bracket type and a rack type array, and is arranged above the surface of a building roof by utilizing the bracket type array and is parallel to the gradient of an inclined roof; while the rack-mounted array is mounted above the flat roof in the orientation and inclination of the best application. In comparison, BIPV is built in the building construction process, while BAPV is built after the building construction is completed, and compared with BIPV which replaces the traditional roofing material, the BIPV needs to have higher strength and better waterproof effect.

The photovoltaic module used by BIPV comprises materials such as a sealing frame, a photovoltaic welding strip, a battery piece, a heat insulation backboard and the like. Because photovoltaic module installs in the roof, after photovoltaic module long-time through the wind and rain, can lead to photovoltaic module's waterproof ability decline, the gap appears in photovoltaic module promptly, leads to the rainwater to get into photovoltaic module through the gap, and the rainwater that gets into photovoltaic module can't discharge again for the rainwater receives the sun and forms steam after shining, and steam long-term accumulation can lead to photovoltaic module's insulation to reduce in photovoltaic module, and accelerates photovoltaic module's ageing speed, influences photovoltaic module's use. Therefore, there is an improvement in the photovoltaic roof, and it should be considered how the rainwater of the photovoltaic module is discharged while meeting the waterproof requirement, so as to meet the requirement of the photovoltaic roof.
