Since the Earth's rotation relative to the sun is not the same all year, with an arc that will vary by season, a dual axis tracking system will consistently experience greater energy yield than its single axis counterpart since it can follow that path directly. The ZRD dual axis solar tracking system has two automatic axis tracking the azimuth angle and elevation angle of the sun automatically every day.

It has very simple structure, with a reduced number of parts and screw connections, no back shadows for bi-facial solar panels, very easy for installation and maintenance. Each set mounting 6 - 12 pieces of solar panels (about 10 - 26 square meters solar panels). The control system can control the driving system track the sun according to the longitude, latitude and local time data downloaded by GPS device, keeps solar panels at best angle for receiving sunlight.

This efficiency makes full use of sunlight, producing 30% to 40% more energy yield than fixed-tilt solar systems, reducing LCOE and bringing more revenue for investors. It is an independent support structure with best terrain adaptability, widely used in mountain projects, solar parks, green belt projects, etc. With over 10 years of research, all driving and control units are specially designed for solar tracking, utilizing brushless D/C motors for long service life and cost efficiency.
