How did you come to a 10.9 degrees per hour?

Also; it would seem that the smaller the increment steps the better average angle on the collector.

If you have it mounted on good bearings it should not require a lot of torque to turn a 2.5 KG collector.

This very interesting topic was discussed in another thread.

I will try to find it.

Urgent replies cost extra. Can you afford it?

When is your project due?

The thread above discussed the advantages and disadvantaged of tracking collectors.

It included a lot of good links related to the topic.
