One forecast depends on the street-facing slope before heritage checks are complete.

Solar panel installers in Cambridge
A roof drawing does not settle a heritage or consent question. Check the exact Cambridge property's restrictions before treating the array as final.

START WITH THE PROPERTY
Resolve heritage questions at the address
For a Cambridge property with possible conservation or listed-building restrictions, send the exact address and any known status before finalising a visible roof layout. The technical drawing and permission route are separate decisions.
BEFORE YOU ACCEPT A QUOTE
Put approvals into the programme
The proposal should show who checks restrictions, who applies where needed and what happens if the preferred roof face is ruled out. Ask for a revised design and output estimate after that decision.
ILLUSTRATIVE QUOTE COMPARISON
What if the visible roof face cannot be used?
Another models a less visible face and marks approvals as pending.
Check the address's restrictions, then request a new output and price for the consented layout. Do not value panels that cannot be fitted.

Give the designer a consumption brief.
Once planning feasibility is clear, recent bills and daytime use help decide how much array is sensible. A consented roof position is only one part of an economic design.
