Mounting frame and support of photovoltaic components and mounting method thereof

Abstract

The invention discloses a mounting frame and a support of photovoltaic components and a mounting method thereof. Required mounting angles of the photovoltaic components are adjusted by adjusting threaded hole connecting positions of support rods and connecting rods in the front and rear rows, two crossbeams penetrate connecting barrels at the upper end of the support rods from left to right or from right to left so as to sequentially connect the support rods in the front and rear rows, the photovoltaic components are fastened in first fastening grooves of a long frame body and second fastening grooves of a short frame body respectively and are adhered by silica gel; the two adjacent photovoltaic components are connected to each other via cant beams; the crossbeams are connected with two crossbeam connecting barrels at two ends of the bottom of the long frame body, and after the photovoltaic components are assembled, the photovoltaic components are fixedly connected with the threaded ends of the crossbeams and the cant beams via nuts. The mounting frame has high mechanical strength and stability, long-term and reliable running of the integral photovoltaic system can be guaranteed; mounting and detachment are facilitated, inclined mounting angles of the photovoltaic components can be adjusted at any time according to solar irradiance of seasonal variation, and accordingly, annual energy output of the photovoltaic components is increased.

Description

technical field [0001] The invention relates to a photovoltaic module, in particular to a photovoltaic module installation frame, a support frame and an installation method thereof. Background technique [0002] At present, the common photovoltaic module is rectangular in shape, and its structure from top to bottom is glass, encapsulation film, battery sheet, encapsulation film and back plate, and there are frames around it to enhance its mechanical strength and facilitate installation. In order to provide stable power supply for photovoltaic modules, they need to be installed and integrated into a photovoltaic system. Common photovoltaic systems include roof photovoltaic systems, photovoltaic curtain walls, and ground photovoltaic power plants. At present, photovoltaic modules in most photovoltaic systems are installed in a fixed way. The installation method is to first assemble and fix the photovoltaic support at a preset inclination angle, and then fix the frame of the p...

Problems solved by technology

With this installation method, the assembly and fixation of the bracket and the installation of the module are carried out in two steps, so the overall installation labor intensity is high; in addition, since the installation tilt angle cannot be changed after the support frame is fixed, the photovoltaic module can only be installed with The fixed tilt angle faces the sun to collect solar radiation, which will make its annual power generation lower

Because the power generation efficiency of photovoltaic modules can reach the highest when the sunlight directly shines on the photovoltaic modules, and for most regions, the solar altitude angle is very different in summer and winter in a year, and installing modules at a single fixed inclination angle will cause other The total annual solar radiation collected is low, resulting in a low annual energy production
