Worm Gear Enclosed IP66 Slow Speed Slewing Drive For Single Solar
Tracking System
Worm Gea Slew Drive Description
Solar energy is one of the fastest growing industries in the world,
today more than 65 GW energy is produced by solar power. Since
solar energy is renewable, it is a good power source, especially
for developing countries. Especially, the solar tracking system is
growing rapidly with the developing advanced technology and the
stable and reliable machanical parts.
The solar panel tracker is designed to follow the sun movement so
that maximum light intensity hits on the solar panel, thus
increasing the power efficiency. Use of a solar tracker circuit in
the field of energy production will increase its efficiency by
almost 25%~40%. This system can also be successfully implemented in
other solar energy based projects water heaters and steam turbines.
There are basically two types of PV trackers. One of them is the
single axis solar tracker and the other is dual axis solar
trackers. Single axis solar tracking system moves the solar panel
from east to west in a day to point in the direction of the sun.
Dual axis solar trackers uses the motor to move the solar panel in
all four directions (North-South & East-West).
