Dual Axis Solar Tracker STMAX

Build a Solar Tracker: How to Build a Dual Axis Sun Tracking System

Track the Sun with the STMAX dual axis solar tracker that you build using the detailed plans in this book. All aspects of the DIY project are covered: Mechanical, Electrical and Software. This modern design uses an onboard microcontroller and MEMS angle sensor technology. All project components are readily available per the detailed parts lists included in the book. The design includes a serial communication interface for remote monitoring and control. The basic 80/20 mechanical platform is easily adapted to your payload: such as solar ovens, optical concentrators, solar electric panels, etc. The 'smart' controller learns daily sun positions for faster aiming over time. Complete software source code for the Picaxe Microcontroller is included. Easy to set up. Multiple options for customization and adaption to your specific project. Check out the PCB and Kit descriptions (below) to get a really quick start. Offered by MTM Scientific, Inc... with over 10 years experience building and operating solar trackers. ISBN 978-0-9971958-0-4, 192 pages, 6"x9" paperback. (See below for electronic PDF version)

Printed Circuit Board

Printed Circuit Board: PCB for "Build a Solar Tracker"

Here is the bare PCB for the project "Build a Solar Tracker". This PCB allows you to get a jump start on the dual axis solar tracker project. Although it is certainly possible to design your own PCB (using the circuit schematics and parts list in the book) this PCB lets you focus on the other parts of the project. This PCB fits nicely inside the weatherproof enclosure we suggest using in the book. Notice that this PCB is designed to use regular-sized through hole electronic components... we did that so you can see what you're doing! A great companion to the plans in the book. Prefer to purchase a complete kit? See the complete electronic kit below.

STMAX : EXAMPLE PAYLOADS

Solar Photovoltaic Panel Solar Stirling Engine PayloadSolar Cooker Oven Payload

The photos above show 3 examples of payloads for the STMAX: A Solar Panel, a Solar Stirling Engine and a Solar Oven. All of these payloads benefit from tracking the sun, and are suitable for the STMAX dual axis solar tracker.   Here is a link to a short (~10 sec) video of the Solar Stirling Engine in operation: Solar Stirling Engine Video



We are working on a new project at MTM to connect a GPS module to the STMAX dual axis solar tracker controller and platform. In this new project the GPS acquires the time, date and location... and the Picaxe-20X2 calculates the sun's position. Here is a link to the details: GPS Solar Tracker
