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.
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 of ZRD dual axis solar tracking 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, so that it can makes full use of sunlight, it produces 30% to 40% more energy yield than fixed-tilt solar systems., reduces LCOE and bring more revenue for investors.
It is independent support structure, with best terrain adaptability, widely used in mountain projects, solar park, green belt projects, etc.
We have been committed to the research of dual axis tracking system for more than 10 years. All the driving and control units are developed by our technical team, special designed for solar tracking system. Therefore, we can control the cost of the dual axis tracking system in a very low area, and we are using brushless D/C motor for driving system which has a very long service time.
