Oblique uniaxial photovoltaic bracket, because flat uniaxial tracking panel vertical line and sunlight always have an Angle.
Flat uniaxial pv mounts are suitable for low latitudes and usually track the sun's altitude Angle to increase the vertical component of solar rays in the battery panel to improve its power generation.
The biaxial photovoltaic bracket system, with two rotating axes moving at the same time, ensures that the solar panel is always perpendicular to the sun's rays...
