Solar roof assessment: pitch, orientation, and shading notes

Good solar surveys capture context: what’s on the roof, what blocks it, and what a designer needs to interpret it.

1) Roof overview photos

• Wide photos that show each roof face
• Close-ups of key features (valleys, dormers, skylights) where relevant
• Reference photos that help scale measurements

2) Obstructions + shading notes

• Photograph obstructions clearly (chimneys, vents, satellite dishes)
• Add notes that explain how each photographed constraint affects the usable roof
• Keep evidence next to the decision it supports

3) Electrical evidence (where required)

Electrical evidence makes it easier to check compatibility without guesswork.

• Meter / cut-out / consumer unit photos
• Main fuse rating and spare ways captured
• Constraints flagged early in the report
