VE9 Horizontal Custom Worm Gear Slew Drive For PV Ground Solar
Energy Tracking System
Standard Worm Gear Description
Slewing drive is a new type of slewing product, which is usually
composed of worm, slewing bearing, housing, motor and other
components. Because the core component adopts slewing bearing, it
can bear axial force, radial force and overturning moment at the
same time.

Applications
1. tipping trackers
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.
2. horizontal single trackers
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 °.
This allows to increase energy production by approximately 15%,
compared to a fixed photovoltaic system.
3. dual axis trackers
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%.
