Working principle:
Popular solar trackers in the market has 3 types:passive, active
and open loop trackers which is distinguished from drive and
sensing or positioning system that they incorporate.
Passive trackers: The tracker has a gas sensing device and the
tracker will move across the sky by using suns radiation to heat
gases.
Active trackers: The tracker has an electric or hydraulic drives
and some type of gearing or actuator. Good future 1P single row
solar panels tracker belongs to this type of active trackers. It’s
also the most popular type in the market right now.
Open loop trackers: Use no sensing but instead determines the
position of the sun through pre-record data for a particular site.
Functions:
The structure is simple, the parts are highly pre assembled, and
the construction time is saved.
Weight-lifting structure with 5 supporting points, shaped table
design combined with a four-link age structure,driven by slewing
drive.
Adapt to outdoor environment,working temperature -40~80C°.
Hot-dipped zinc galvanization will extend the work life of the
brackets
Independent driving single row design, no linkage rod, strong
terrain adaptability and high plot ratio.
Automatic control: The solar tracking system will provide
protection automatically for different weather (rain, snow, high
winds, etc. )
