One array uses both the main roof and the newer lower slope.
THE BIRMINGHAM FIELD GUIDE / SOLAR PANELS
Solar panel installers in Birmingham
Two roof planes do not necessarily contribute equally. Ask for generation and shade assumptions by panel group on a Birmingham solar design.
START WITH THE PROPERTY
Separate the roof faces
If a Birmingham home has a main roof and a later extension, each slope may have different shade, pitch or wiring access. Photograph them separately instead of asking for one panel count against the whole address.
BEFORE YOU ACCEPT A QUOTE
Read the forecast by section
A good proposal explains why each panel group belongs where it does, how the inverter handles those groups and what the estimates assume. If one face is weak, ask whether its extra panels repay the added installation complexity.
ILLUSTRATIVE QUOTE COMPARISON
Should panels go on the extension roof?
A simpler scheme uses the stronger main slope alone.
THE DECISION
Ask what the extension group adds in annual kilowatt-hours and what it adds in mounting, cabling and inverter complexity. More panels need a measurable contribution.

Check whether the roof is ready.
Tell us about known leaks, ageing coverings or scheduled repair. A promising generation estimate is less useful if the array has to be removed soon for roof work.
