1, common double shaft type tracker needs two cover motions, respectively in order to follow the tracks of solar illumination angle change every day and to follow the tracks of the change of Various Seasonal sun irradiation angle, so this device causes installation investment larger because material cost is higher at present.
2, flat single axle tracking means only has a set of kinematic system, does not follow the tracks of the kinematic system of Various Seasonal declination angle change, so cannot be vertical with sunshine in high latitude area photovoltaic panel, makes annual conversion efficiency lower.
3, in flat axle tracing system, often each own a set of turning axle drive system of support followed the tracks of by cover, which adds photovoltaic plant investment and maintenance cost.
4, tiltedly single axle tracking means needs photovoltaic panel to lift certain angle, and in order to eliminate the change at part solar latitude angle, therefore need to consider mutual occlusion issue when arranging each tracker, cause effectively to utilize soil, floor area is larger.
