DIY Handcrafted Solar Tracking System

The “Modular” design will allow you to construct any size solar tracker, single or dual axis, and adapt it to any type of device. Photovoltaic PV solar panels, Solar Concentrators, Solar Heaters Solar Cookers and even mobile and marine trackers are possible with our modular design. The new circuit designed by Mike Mladejovsky, PhD uses an inexpensive comparator integrated circuit and Darlington pair transistor outputs to drive up to a 1 amp DC motor. While this circuit can drive large motors it is also possible to build mini-trackers with input voltages as low as 3.6volts. The sun sensor is simplified using only six LEDs and the drive units are slew type designs driven by planetary geared drill motors which provide lots of torque and are self locking.
