what this page does not tell you
Ballast quantities, wind loads and the imposed-load cases are not in the installation manual and are not guessed at here. They live in the declarations of performance — see the DoP tables and the rest of documents. What the 70° and 90° in step 7 mean is explained in 70° and 90° explained. For anything the documents do not answer, ask us.
