Applications
The solar tracker slew drive is mainly used for the following solar
tracking systems:
1.Horizontal single-axis solar tracking system. For horizontal
single-axis solar tracking system, the main beam of solar panel
will adjust the angle to precisely track the declination angle.
This kind of slewing drive is only applied for low latitudes area.
2.Tilted Single-Axis Tracking system. Tilted Single-Axis Tracker is
suitable for areas with latitudes higher than 40 degrees, which can
maximize the benefits of power yield.
3.Dual axis solar tracking system. Dual axis solar tracking system
is "altitude+azimuth" full-tracking system, it moves along two
rotation axes with two rotational degrees to completely track the
sun's orbit and maximize solar energy reception. This kind of
slewing drive is suitable for high-latitude areas and the
efficiency of power generation will be increased over 35%, which
significantly improve the efficiency of solar power generation
system.
Packaging and Shipping
Inner Packaging: anti-rust plastic film ; vacuum plastic bags.
Outer Packaging: hard carton; wooden case ; wood pallet.
Shipping Term: by express; by air; by land; by sea.
For samples, since the slew drive is with small dimension but heavy
weight weight, it's not cost effective shipping by sea while the
express shipping the cost-effective way, our logistitic staffs will
asked TNT, DHL, UPS, FEDEX, to compare the express price in order
to find the most cost effective way.
If in bulk order in the future, we recommend ship by sea.
