MTM Scientific, Inc... Solar Tracker Circuit Kit

The SOLAR TRACKER CIRCUIT KIT from MTM Scientific contains all the electrical parts you need to build a circuit which will automatically find and follow the sun across the sky. This tracker circuit finds the sun at dawn, follows the sun during the day, and then resets again the following morning. This kit is perfect for driving a single axis solar tracker with a 12 VDC gear motor that you provide. The kit includes 2 CdS photocells, an IC comparator, 8 resistors, 4 diodes, 2 limit switches, 2 DPDT relays and complete instructions. A printed circuit board is also included with the kit, which makes it easy to assemble and test the circuit quickly. The circuit is powered by the same 12 VDC that drives your motor. Single axis solar tracking is great for projects such as solar optical concentrators, solar ovens, fresnel lenses, and solar electric photovoltaic panels. The instructions explain how the circuit works, how single axis sun tracking works and how to select a DC gearhead motor. This kit is perfect for the person that wants a quick start on building a single axis solar tracker. This kit ships by 1st Class Mail in the U.S.A, and by Air Mail to anywhere else in the world for the same price.

Example of Solar Tracking for a Solar Panel

Solar Tracker Circuit Specifications: 3 Amp Max Motor Current, 12 VDC Supply

Please note: This circuit kit is for controlling a 12 VDC electric motor that you provide. To track the sun you will also need to build the mechanical drive for having your motor move your project. The instruction booklet gives some examples. Note also that construction of this kit requires soldering.
