    Design Changes/Revisions

    Changes occur in the proposed solar system many a times. Design Presentation can step in at any stage and can provide the required drafting changes in the Rooftop Solar Drawings. We can work on changing racking, electrical equipment, mounting planes, etc.

    As-Built Drawings

    As-built drawings show how the system was actually installed and reflect any changes made to the design during installation. As-built Rooftop Solar Drawings provide a record of how the system was actually installed.

    To produce the as-built drawings we require either the hand sketch of the changes made during the installations or photographs so that we can amend the original Rooftop Solar Drawings.
