Are the solar panels built correctly?

I have had a company build the frame for our garage with a lot of errors. Now I am wondering if I need to be worried about the construction of the trusses (see image). The plan and section drawings they received show W trusses.

This is an OK execution (and not entirely uncommon) for trusses with moderate span.

For longer spans, it usually transitions to trusses of the W or WW type.

Ok, the span is a little over 6m.
Thank you for a quick response.

I have a 4-meter span on the garage and the roof trusses look like the ones you sketched but without the diagonal braces.
So I assume that your design works.

Do you have strong reasons to distrust these trusses?
Calculation documentation should be included in the delivery. The building committee and/or the construction supervisor may require to see this.
