Positive: Good accessibility. Quick and useful answers to technical queries. Clear website. Good quality and good packaging of the components used.
Negative on the Balkony: The sliding nuts on the Balkony should have bent up corners or a spring band on all 4 corners. The aim is that the sliding nuts hook in the mounting groove and not align again longitudinally to the mounting groove when tightening, or slip completely out of it.
P.S. There are such sliding nuts.
The lower module clamp on the Balkony is open at the bottom.
If this lower module clamp is/is not properly tightened, the module could slip down out of the mount.
It would be nice if the spring, summer, fall and winter elevation to the sun was not only possible in the fixed steps, but variable. This could be realized by two parallel running aluminum rails, each with a longitudinal groove, which can be pushed further apart or more together and then fixed with a wing screw variable. This could then be offered as an optional accessory.
The dummy plug of the inverter must always be included in the accessory pack for the inverter and not be included in other places.

thank you very much for your evaluation.
Unfortunately, there are no approved mounts with ballasting for flat roofs that have more than a 20-degree slope. Larger installations usually have a 15-degree slope. A steeper slope would mean much too high a wind load, plus 20 degrees produces almost the same yield as 30 or 40 degrees. In this case, it is possible to choose a Yuma front as an alternative. In this case, however, the bracket must be properly screwed to the substrate. If you still have questions, please feel free to contact our customer support. We will be happy to advise you at any time during our business hours.
Have fun with your solar power production
Your team from Yuma
