   Stamped Engineer Letter (PE-sealed)

   Licensed Professional Engineer's letter attesting to structural adequacy of the roof for the proposed PV array.

   Flower Mound note: Hilly terrain + large-lot homes in Flower Mound sometimes hit exposure-category complications in the wind-load calc. Have the PE verify Exposure B vs C for the specific site.
