The ZRP flat single axis solar tracking system has one axis tracking the azimuth angle of the sun. Each set mounting 10 - 60 pieces of solar panels, single row type or 2 - rows linked type, given a 15% to 30% production gain over fixed-tilt systems on the same size array.
At present, the flat single axis solar tracker in the market mainly has two solar array layout forms: 1P and 2P.
The 1P layout scheme is undoubtedly better in structural stability and has good wind and snow pressure resistance performance, but it uses a larger amount of steel and the number of pile foundations will inevitably increase, which will bring a small increase in the total construction cost of the solar power station. Another disadvantage is that its central main beam will bring more back shielding to the bifacial solar modules than the 2P layout scheme.
The 2P scheme is a scheme with more cost advantages, but the core is to solve how to ensure the firmness of the system structure when 500W+ and 600W+ large area solar modules are widely used. For the 2P structure, in addition to the traditional fishbone structure, a double main beam structure has been introduced, which can effectively support the solar panels, prevent the sagging at both ends of the solar modules and reduce the hidden cracks of the solar modules.
