Has anyone used these to mount solar panels on rv roof ?

That's a good question. This track for sure accept 1/4 hex bolts in the T track side. All depends how big are the solar panels. The matter here is when you are on the road.You dont want those solar panels being taken off the roof by the wind.

What are the exact dimensions? The diagram is incorrect including the metric conversions. The interior height can't be 16.8mm if only 10mm high.

6.67 mm interior . width outside is 18.95. height outside is 9.42

Très bons petits rails pour de petits montages ou gabarits. Prépercés et fournis avec leurs vis. Pour ce prix-là, pas moyen de faire mieux, je crois.
