Photovoltaic assembly installation support and roof photovoltaic system

Abstract

The invention provides a photovoltaic assembly installation support and a roof photovoltaic system comprising the same, relating to the photovoltaic generating technology field. The photovoltaic assembly installation support comprises No.1 support rods, and No.2 support rods; the No.2 support rods are arranged between the No.1 support rods and are crossing with the No.1 support rods in a perpendicular manner; the No.2 support rod comprises a support rod main body with an insertion groove in the middle and a baffle arranged on the upper surface of the support rod main body; the cross section of the support rod main body is of an U shape; the tops of the No.1 support rods are provided with positioning grooves for bearing and positioning the No.2 support rods; the height of the left side wall of the positioning groove is equal to that of the support rod main body; the height of the right side wall is equal to that from the lower surface of the support rod main body to the lower surface of the insertion groove; the top of the No.1 support rod is provided with a glue injection groove which is arranged along the length direction of the No.1 support rod. The roof photovoltaic system comprises a photovoltaic assembly installation support, a frameless photovoltaic assembly and a roof crossbeam; the frameless photovoltaic assembly is installed on the photovoltaic assembly installation support which is fixed on the roof crossbeam.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a photovoltaic module installation bracket and a roof photovoltaic system. Background technique [0002] Among all kinds of renewable energy, solar energy covers a wide area and is an inexhaustible clean energy. Solar photovoltaic power generation technology is currently the fastest-growing and most cutting-edge research field in the field of solar energy utilization. [0003] In recent years, many photovoltaic power plants have been built in various parts of our country. The photovoltaic power generation system usually includes two types: roof photovoltaic system and ground photovoltaic system. Existing rooftop photovoltaic systems are difficult to promote due to the following problems: Most existing rooftop photovoltaic systems use framed photovoltaic modules (although framed photovoltaic modules are much heavier than frameless photovoltaic modules and cos...

Problems solved by technology

Existing rooftop photovoltaic systems are difficult to promote due to the following problems: Most existing rooftop photovoltaic systems use framed photovoltaic modules (although framed photovoltaic modules are much heavier than frameless photovoltaic modules and cost less It is also much higher, but frameless photovoltaic modules are rarely used in rooftop photovoltaic systems due to inconvenient fixation and complicated installation). The above-mentioned photovoltaic modules with frames are fixed on the roof beams through brackets, while photovoltaic Due to its heavy weight, it will directly lead to a large load on the roof. In order to ensure the safety and stability and reliability of the photovoltaic system, the building needs to have strong load rigidity and high bearing capacity. Therefore, the existing roof Photovoltaic systems are not only expensive but also have high requirements for buildings
