Tunnelplan Sun tracker 3

The solar panels measures 1100 mm x 520 mm and is aimed at the sun with a cheap linear motor, a solar sensor and software (under 100 euro). The construction is further made of wood.

The panels are attached to the wooden beam with a hinge. This beam is attached with two hinges to a short wooden beam that is screwed against the wall with screws.

The sun tracker automatically follows the sun every day from east to west and then returns to its starting position. The angle to the sun of the panel is adjusted manually in the winter, spring / autumn and summer.

For sun angles see https://www.suncalc.org an idea from James Biggar
