位于Beckhoff的TwinCAT太阳定位电脑计算软件能够在不用感应器的条件下，准确的计算全球任何时间任何地点的太阳角度。这种灵活的解决方式对抛物线太阳能镜面，光伏太阳能系统以及其他太阳能系统的太阳追踪设计带来了极大的便利。这种自动的太阳定位追踪主要目的是获取太阳辐射的最大值，该软件的控制计算极为精确，对于太阳角度的误差计算精确度在+-0.001°，该软件也有着其他用途，例如，建筑物的自动控制系统或者风涡轮的阴影闪烁率计算。
High-precision PC-based solar tracking
15.07.2010: The TwinCAT Solar Position Algorithm software function block from Beckhoff enables exact calculation of sun angles anywhere in the world at any time, without the use of sensors. This flexible solution is ideal for parabolic mirror and photovoltaic systems as well as for other solar power plant designs that automatically track the sun's position for optimum utilisation of the sun's rays. The control algorithm, which calculates sun angles with a precision of ±0.001°, can also be used for other applications such as in building automation or with wind turbines for shadow flicker calculations
