How much the roof could generate.
Usable area, orientation, shade, and a system sized to the goal. Not a percentage of the roof.
Guide
A commercial solar feasibility study tests whether a rooftop is worth pursuing before you pay for surveys, installer visits, or detailed design.
How the answer is built
Usable area is measured per roof, not assumed as a percentage, so the system that gets sized is one that fits.

Checklist, PDF
For estates, asset management and procurement teams weighing rooftop PV on UK commercial buildings, one roof or a portfolio. Enter a work email for the print-ready checklist. This is not a site enquiry.

Four questions, in writing
Usable area, orientation, shade, and a system sized to the goal. Not a percentage of the roof.
Payback, NPV, and a cash flow from assumptions you can challenge. A band for cost, not a single invented price.
Wind, structure, grid, and planning. Each with a next step. Screening, not sign-off.
Pursue, pursue with conditions, or park. A written call before survey, design, or an installer visit.
The study ends in pursue, pursue with conditions, or park. A board, a landlord, or an asset manager can read it without being a solar specialist. It is not detailed design, a structural certificate, or an installer proposal.
A structural report tells you whether a roof will hold a system you have already decided to buy. Feasibility tells you whether to buy anything, and at what size. Design and installation in the UK are already good. They start after this answer.
Send an address. The roof is rebuilt, the years are run, and the decision comes back with the workings attached. Park is a successful outcome when it stops spend on a roof that was never going to clear.
