Solar panels are more efficient when they face the sun correctly. Often, you need a complicated PLC, sensors and motors to orient the panel correctly. My solution is simpler. One motor drives the azimuth (ie/ horizontal plane) at a prescribed speed defined by time of day and time of the year. A stationary sleeve pushes a strut attached to the bottom of the PV Panel upwards, changing the altitude (ie/ vertical plane) at such a rate that the panel will always be facing the sun. The shape of the sleeve is dependant upon location. So we must 3D print each sleeve to suit the location of the PV panel. Of course, there will be seasonal variations - but this is actually insignificant. At solstice, a 23.4° offset will have an 8% reduction in electrical output. An 8° has only 1%. Combined with the reduced energy consumption of a single motor and simplified PLC controller with the advantages of a dual axis solar tracker, there are some significant benefits to this design. Please give me feedback if you have any.
