VE7 Slew Drive Gearbox, Envelop Worm With High Torque For
Horizontal Single Axis Solar Trackers
Description
In photovoltaic power generation, the more light energy absorbed by
the interface layer of the solar panel, the greater the current
generated. When the sunlight hits the surface of the solar panel
vertically, the photovoltaic effect is the best, and the
photoelectric conversion efficiency is the highest. People can't
hold the sun to align the solar panel to keep the vertical
irradiation, but you can let the solar panel move with the movement
of the sun, from sunrise to sunset, always maintain the best
vertical state of receiving sunlight. This method is called
photovoltaic tracking technology, and a slewing drive is required
in photovoltaic tracking technology.
The slewing drive device is a product with simple structure, easy
installation, low cost, easy maintenance and improved reliability.
