As to know,the optimal operating conditions for a PV system are present if the irradiation on the solar generator area is continuously vertical.To realize this in practice the whole generator area must be continuously adjusted to the actual position of the sun.Solar panel tracking mounting systems can either utilized only one axis or two axis.

One axis solar tracking effects only one angle.The sun is perpendicular to the module only in one plane.The best conditions for one-axis tracking are obtained if the axis is parallel to the earth’s axis. An experimental study found that insolation on an array could be increased by 18% compared to a fixed array by azimuth tracking around a vertical axis or by 11% using a tilted-axis tracker.

With 2 axis solar panel mount tracking the sun is always perpendicular to the module.Power out put can be further increased by tracking the sun along both the north-south and east-west axis.Helwa (2000) measured a 35%~40% insolation improvement relative to a fixed-tilt array. However,both the capital and maintenance costs can be high and few large systems are currently installed.
