Single axis tracking photovoltaic bracket

What is a flat single-axis solar tracking bracket?

A flat single-axis solar tracking bracket is a photovoltaic bracket that can follow the sun's sunshine trajectory. It rotates only on one axis, the horizontal axis, and is parallel to the ground, so it is called a "flat single axis". It allows the solar panel to rotate along one axis (usually east-west) within a day so that it always faces the sun, thereby maximizing the capture of sunlight.

The test results of the power generation efficiency of flat single-axis tracking photovoltaic brackets in different latitudes show that the power generation benefits of flat single-axis solar tracking systems in low latitudes are significantly higher than those in high latitudes. It is generally believed that this type of tracking bracket is more suitable for deployment in areas with a latitude below 30°. Compared with the tilt fixed bracket, it can increase the power generation by 20%-30%.
