Can draw from upper table: the radiant quantity on constant cant angle inclined-plane increases by 14% than the radiant quantity of surface level
Radiant quantity on uniaxial horizontal tracing surface increases by 40% than the radiant quantity of surface level
The radiant quantity that single shaft inclines on angle of latitude inclined-plane increases by 50.8% than the radiant quantity of surface level
Radiant quantity on double-axis tracking inclined-plane increases by 56% than the radiant quantity of surface level
Reach a conclusion from above analysis:
1) double-axis tracking device complex structure, cost are high.
2) uniaxial horizontal follows the tracks of the low latitudes being only suitable for less than 30 °.
3) single shaft incline angle of latitude follow the tracks of be applicable to more than 30 ° latitude.
As for which kind of tracking mode of selection according to determining from different places.
