Installer Pre-Brief Checklist

Three documents before the quote.

Send these three items and we issue a fee proposal within 24 to 48 hours, with a confirmed site visit date the same week. Most installers carry all three as standard.

01

Roof boundary image or PV design file

Either option carries the same weight. Send whichever you have ready.

Option A Google Earth screenshot, Apple Maps satellite image, or an aerial photo with the roof boundary marked and the proposed array zones outlined.
or
Option B PV design file from any software: Pylon, PV*SOL, OpenSolar, Aurora, HelioScope, PVsyst, or an AutoCAD or PDF layout export.
02

Mounting system specification

The mounting manufacturer specification sheet showing uplift, static, and snow load values, plus the fixing method (penetrating screws, clamps, ballast, or hybrid). Confirms what loads the roof needs to accept and whether the warranty constraints permit penetrating fixings. A link to the manufacturer's online datasheet for the specific rail or clamp model is acceptable.

03

Panel datasheet

The panel manufacturer datasheet showing module dimensions, weight in kg, glass thickness, frame profile, and electrical characteristics. Gives us per-panel mass and wind-coefficient inputs for BRE Digest 489 calculations. Manufacturer PDF preferred; a make and model number alone is enough to start.

Helpful, not required

The items below are not mandatory. Where available they sharpen the report and reduce the engineering assumptions we have to make. If you have none of them, that is fine: we work to the brief you provide.

Existing structural drawings (as-built or original-design)
Original structural design calculations or design statement
Roof construction details (sheet manufacturer, profile, age)
Recent thermal or condition surveys of the roof
Site access plan, RAMS, or relevant CDM information
Building consent or listed building status, where applicable
Previous roof repair or replacement history
Asbestos register entry where the roof is pre-2000
