Photovoltaic system and solar tracking support thereof

Abstract

The present invention discloses a solar tracking support. The solar tracking support comprises a bearing portion configured to support and fix a photovoltaic module, a pedestal and a regulation portion configured to regulate the angle of the bearing portion relative to the pedestal; the first end of the bearing portion is hinged with the pedestal, two ends of the regulation portion are respectively connected with the bearing portion and the pedestal; the first end of the regulation portion can be moved and fixed in the length direction of the bearing portion, and / or, the second end of the regulation portion can be moved and fixed in the length direction of the pedestal so as to achieve angle regulation of the bearing relative to the pedestal. The solar tracking support is simple in structure, low in device cost and simple to operate, is suitable for usage of a small-type photovoltaic system, is not high in operator requirements and brings convenience for popularization and application.

Description

Technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a sun tracking bracket. Background technique [0002] In recent years, with the rapid development of photovoltaic power generation and the continuous improvement of popular environmental awareness, more and more people choose to install small photovoltaic systems. [0003] However, due to changes in the solar altitude angle, the benefits of fixed photovoltaic modules cannot be maximized; the so-called solar altitude angle, for a certain place on the earth, the solar altitude angle refers to the distance between the incident direction of sunlight and the ground plane Included angle, professionally speaking, the solar altitude angle refers to the angle between the sun's rays in a certain place and the surface section that passes through the ground and connects to the center of the earth. When the sun's altitude angle is 90°, the solar radiation intensity is at its m...

AI Technical Summary

Problems solved by technology

However, the photovoltaic tracking system is usually used in large-scale photovoltaic systems due to its complex structure and high installation and use costs; in small photovoltaic systems, there is no economic advantage at all, and it cannot make ends meet, and its complex structure makes operation and maintenance difficult. Higher, and some non-electric tracking devices in the prior art also have complex structures, which are inconvenient to manufacture, install and use
