DIY Heliostat Sun Tracker Solar Power Fresnel Lens


This is our first attempt at a useable Heliostat for our Fresnel Lenses. In future videos I will have all the information for a DIY system using very easy to find materials. We are developing a controller that is simple to program and can control any type of DC or even AC motors. Once completed I will share some open source information.

    I think Heliostat is the correct description of the device. A heliostat is something that tracks the position of the sun. It’s also used in Telescopes.

    When you’re done, it would be great if you posted a link to the source code for your heliostat. Also a parts list would be awesome!

    I like what you are doing.
    However I have a “nit pick”.
    You have described your Fresnel Lens Concentrator as a “heliostat”. This is not correct.

    1. A heliostat is a two axis solar tracking mirror that reflects sunlight onto a fixed receiver.

    2. Furthermore, the geometry between the Sun, Mirror, and Receiver are constantly changing throughout the day. (There is a special case, the coelostats, where light is sent along the polar axis and where the geometry is approximately fixed throughout the day.)

    3. In general the mirror is aimed normal to the bisector between the sun and receiver.

    In yours the geometry between the Sun, Lens, and Receiver is fixed.
