HELIOSTAT SUN TRACKER SOLAR POWER

This is our first attempt at a useable Heliostat for our Fresnel Lenses.

The trouble is this is not a heliostat.

A heliostat is generally a mirror that reflects sunlight onto a stationary target. Furthermore, there are exceptions, the geometry between the sun, mirror, and the target constantly changes throughout the day.

Here are some examples:
Examples of "Receiver Axis" heliostat mounts.

Vertical axis heliostat mounts.

And examples of historic mechanical heliostats and coelostats, (2 mirror heliostats).

Your tracker always aims at the sun and the geometry doesn't change throughout the day. This is a basically a conventional Fresnel lens solar tracking concentrator

Don't get me wrong, I applaud your work. Please keep it up.
