Description

Photovoltaic system

Technical Field

The invention belongs to the field of photovoltaic devices, and particularly relates to a photovoltaic system.

Background

Compared with a traditional fixed photovoltaic system, the photovoltaic system has the advantages that the time for the components to face the sun is longer, the received sunlight illumination is more sufficient, and the power generation efficiency is remarkably improved.

The photovoltaic system mainly comprises a horizontal single-axis tracking mode and a double-axis tracking mode, and the difference between the horizontal single-axis tracking mode and the double-axis tracking mode is that the horizontal single-axis tracking mode is used for tracking in a single direction and only tracking in the east-rising-west-falling-west direction of the sun. The double-axis tracking is to perform tracking in two directions, namely tracking in an east-west direction and tracking in a north-south direction with different sun altitude angles along with different seasons. The effect of the tracking in the north-south direction is more obvious along with the higher latitude. Therefore, compared with the flat single-axis tracking, the double-axis tracking system has the remarkable improvement of the power generation amount.

The multi-stand double-shaft tracking system is a novel tracking system combining advantages of a flat single shaft and advantages of a traditional T-shaped double-shaft system, and is divided into a main beam and an auxiliary beam of each subunit in the multi-stand double-shaft tracking system, photovoltaic assemblies are arranged on the auxiliary beams, the auxiliary beams are hinged with the main beam through connecting pieces, and the auxiliary beams can rotate in the axis direction of the main beam. The main beam drives the components on all the secondary beams to rotate and track in one direction through the circle center of the main beam, and the secondary beams drive the photovoltaic components to rotate and track in the other direction.

Generally, as shown in fig. 1, the photovoltaic modules 102 are located on both sides of the main beam 101 in the width direction and lower than the upper plane of the main beam 101, and the sub-unit link is located above the main beam. When the double-axis system performs sun tracking in the structural mode, the main beam, the connecting rod support and the sub-unit connecting rod form a shadow on the surface of the component, so that the power generation amount of the component is reduced.
