Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic panels, and particularly relates to a photovoltaic module mounting bracket and a roof photovoltaic system. BACKGROUND

[0002] The photovoltaic module mounting bracket is a key structural component for fixing and supporting the photovoltaic cell panel in the solar photovoltaic power generation system, and its performance directly affects the installation stability, power generation efficiency and system life of the module. In the roof photovoltaic system, the bracket needs to adapt to different types of roofs (such as sloping roofs and flat roofs) and complex installation environments. At present, the common roof photovoltaic brackets on the market mainly include fixed type, seasonal adjustable type and a small amount of single-axis tracking type. The fixed type bracket has simple structure and low cost, but the installation inclination angle and azimuth angle cannot be changed once they are set, which cannot adapt to the position movement of the sun at different times of the day and in different seasons of the year, resulting in that the photovoltaic module cannot continuously receive the solar radiation at the best angle, which significantly reduces the annual power generation of the system. The seasonal adjustable bracket allows users to manually adjust the inclination angle several times according to the seasonal changes, which improves the average annual power generation efficiency to a certain extent, but still cannot solve the energy loss caused by the daily change of the sun's azimuth. Although the dual-axis tracking bracket applied to large ground power stations can realize real-time automatic tracking of the azimuth and elevation angles, maximize the power generation, but its structure is complex, the cost is high, the maintenance requirement is high, and it is often large in size and weight, which is difficult to adapt to the load bearing limit, space constraint and economic requirement of ordinary residential or commercial roofs.

[0003] Therefore, the photovoltaic installation and adjustment frame commonly used in the prior art in the roof scene can only be fixed at an angle or can only be adjusted at a limited and non-real-time inclination angle, and lacks an effective mechanism that can economically, reliably and conveniently adjust the azimuth and elevation angles of the photovoltaic module simultaneously or cooperatively under the limited space and load bearing conditions of the roof, so as to realize real-time tracking of the sun's azimuth and elevation changes to maximize the power generation. The lack of such adjustment capability has become one of the key technical bottlenecks restricting the further improvement of the power generation efficiency and the return on investment of the roof photovoltaic system.
