Electric adjustable photovoltaic bipv supportTechnical Field
The invention belongs to the technical field of photovoltaic power generation, and particularly relates to an electrically adjustable photovoltaic bipv bracket.
Background
BIPV refers to a technology for integrating a solar power generation product onto a building, and the integration of the building is different from the attachment of a photovoltaic system onto the building, and the BIPV photovoltaic module needs to integrate the photovoltaic power generation function onto the building.
The angle of the sun in one day is changed constantly, the incident angle is the included angle between the incident light and the normal line of the plane, and when the incident angle of the sun light which is directed to the plane of the photovoltaic component is minimum, the solar radiation utilization rate of the photovoltaic panel is maximum, but because the incident angle changes with time, in order to minimize the incident angle of the sun light of the photovoltaic component in time, the method for enabling the photovoltaic panel to always track the sun light source and minimize the incident angle of the sun light is the most effective method.
In addition, as the existing photovoltaic panel is arranged on a building roof, severe weather such as heavy rain, heavy snow, sand dust and the like is inevitably encountered, under the environment, firstly, the photovoltaic power generation basically does not generate power generation efficiency, secondly, the photovoltaic power generation is damaged to different degrees, timely protection is needed, and the existing BIPV photovoltaic bracket does not have active risk avoidance and protection structures and functions;
In addition, the existing BIPV photovoltaic support is directly paved through the support, so that the reduction and the scaling of the space position cannot be realized, the roof is occupied by the photovoltaic panel all the time, and efficient emptying action cannot be realized under the conditions of overhauling, maintaining and other situations needing to vacate space unless the BIPV photovoltaic support is disassembled, so that the use efficiency is low. It is therefore important to provide an electrically adjustable photovoltaic bipv mount that addresses the above issues.
