One sales plan counts roof area as a rectangle.
THE NOTTINGHAM FIELD GUIDE / SOLAR PANELS
Solar panel installers in Nottingham
A dormer changes more than the panel count: it can cast shade and interrupt mounting. Request a surveyed Nottingham roof plan before comparing output.
START WITH THE PROPERTY
Subtract the roof interruptions
A Nottingham roof with dormers or roof lights may have less uninterrupted area than its footprint suggests. Share clear photographs and ask for panel dimensions on a marked roof drawing.
BEFORE YOU ACCEPT A QUOTE
Check the count against the drawing
Every quoted panel should fit the final layout with realistic spacing and access. The generation estimate needs to be recalculated if the site survey removes a row or changes the inverter arrangement.
ILLUSTRATIVE QUOTE COMPARISON
Does the panel drawing fit around the dormer?
Another uses measured panel dimensions around the dormer and roof light.
THE DECISION
Ask for the surveyed array plan, usable roof area and updated annual estimate. A pre-survey panel count is a starting sketch, not a system specification.

NEXT STEP IN NOTTINGHAM
Investigate roof condition before fitting.
If the covering needs repairs, time them ahead of the panels. Ask how the mounting will be weatherproofed and who inspects any disturbed roof area.
