9 Inch Vertical Small Slewing Drive Gearbox For Horizontal Single Solar Tracking System
Description
According to their construction characteristics, solar trackers are divided to:
Tilt trackers are the simplest to make and rotate around the east - west axis. The solar panel rises or falls (usually manually twice a year) towards the horizon, so that the angle to the ground is statistically optimal according to seasonality. These trackers offer an increase in production of less than 10%, to rarely justify a servomechanism.
Flat Single trackers aim to follow the sun throughout the sky on their daily journey, regardless of the season of use. In this case, the axis of rotation is north-south, while the height of the Sun above the horizon is ignored. These trackers are particularly suitable for low-latitude countries, where the sun's path is, on average, wider during the year. The rotation required for these structures is wider than the inclination, sometimes up to ± 60 °.
These followers allows to increase energy production by approximately 15%, compared to a fixed photovoltaic system.
Solar trackers with two degrees of freedom
The most sophisticated solar trackers have two degrees of freedom, with the aim of perfectly aligning the orthogonal photovoltaic panels with the sun's rays in real time. The cheapest, but not the only, way to do them is to mount one tracker on another. With these solar trackers there are increases in the production of electricity that reach up to 35% -40%.

Advantages Of Slewing Drive Solar Tracker
The sun is a constantly moving target. Single axis slewing drive solar tracker move from east to west daily to get the most sunlight, while dual-axis solar trackers move with the sun from dawn to dusk from not only from east to west but also north to south to maximize energy production throughout the day.
