01
What this check covers
Property type, roof form, orientation and visible shading help frame an initial conversation. The result deliberately avoids false precision.
02
What it cannot see
Structure, roof covering condition, precise geometry, electrical capacity, asbestos, cable routes, fire access, planning constraints and network requirements need evidence or professional review.
03
Use the result well
Save the questions mentally or copy them yourself, then ask more than one competent installer to explain how the final design deals with each issue.
