A solar roof installation is not simply a PV job and it is not simply a roofing job. It requires a coordinated roof-side, electrical and documentation plan. The manufacturer can define the product package and provide the available technical material; the local roofing and electrical teams are responsible for confirming the building, code, weatherproofing, safety and grid-connection requirements for the actual project.
This guide helps buyers, distributors, installers and contractors understand the planning sequence before requesting a quotation or training material. It is not a substitute for local design, permitting, structural review or electrical commissioning.
1. Confirm that the project suits an integrated solar roof
Start by establishing whether the project is a new build, a re-roofing project or an existing-roof retrofit. An integrated solar roof is usually evaluated when the roof surface itself is being designed or renewed and when appearance, coordinated roof coverage or a complete package matter to the buyer.
The first discussion should identify the project country, building type, estimated roof area, roof form, intended product line, delivery location and programme. Drawings are useful, but clear roof photos and a basic sketch can be enough for an initial product-fit conversation.
2. Define the roof layout before ordering components
A complete system normally includes active power-generating elements and matching inactive elements. The roof layout needs to show which areas generate power and which areas require inactive coverage, along with the roof edges, ridges, valleys, penetrations, skylights and other transitions.
This stage helps avoid a common procurement mistake: ordering only a quantity of active tiles or sheets before the roof-completion scope has been considered. See Solar Roof System vs Solar Roof Tiles for the difference between a product and a complete roof package.
3. Agree the responsibilities before work starts
A project works best when responsibilities are explicit. The exact split depends on the buyer, market and contract, but the following framework is useful.
| Party | Typical responsibility to clarify |
|---|---|
| Manufacturer | Product data, available components, supply scope, packing information and manufacturer-side installation notes. |
| Distributor or project buyer | Product selection, commercial scope, delivery coordination and the information needed for quotation. |
| Roofing team | Roof substrate, local waterproofing method, fixing execution, flashings, ventilation and workmanship under local requirements. |
| Electrical professional | System design, cable routing, protection, inverter compatibility, testing, commissioning and grid requirements. |
| Project owner / developer | Local approvals, building inputs, programme coordination and final project decisions. |
4. Prepare the roof base and roof-side details
The roof should be assessed by the local roofing team before active elements are installed. The team needs to confirm the substrate condition, roof geometry, drainage, weatherproofing layers, ventilation approach, battens or supporting structure where applicable, and the treatment of penetrations and transitions.
Product imagery can demonstrate components, but it cannot replace a site-specific waterproofing or structural decision. A buyer should request the relevant component schedule and review it with the local team before beginning work.
5. Install active and inactive elements as one roof layout
Once the base and layout are confirmed, active elements are installed with the matching inactive elements and roof-completion parts specified for the product line. The objective is a continuous roof surface with defined transitions, not a collection of separate PV modules.
The installation sequence, fixing method and component details must follow the current manufacturer documentation for the supplied system and the local roofing plan. If the project includes unusual geometry, a skylight, a vent, a valley or a wall connection, those conditions should be discussed before materials are shipped.
6. Coordinate electrical work with the roof installation
Active roof elements require an electrical design that is appropriate for the project and local regulations. Cable routing, connectors, string configuration, protection, inverter interface and commissioning should be planned by qualified electrical professionals. Electrical work should never be improvised from a generic web article.
A manufacturer can explain the available product connection concept and data. The local electrical team must confirm the final design and all code, safety, inspection and utility requirements.
7. Complete checks, documents and handover
Before handover, the project team should confirm the roof-side workmanship, electrical tests, documentation, product records and any local inspection or grid-connection process. The exact checklist belongs to the target market and contract. A clear handover record helps the buyer understand which documents are product documents, which are installation records and which remain the responsibility of the local team.
Buyer checklist for the first manufacturer discussion
Bring the following to the first conversation where available:
- Project country and delivery destination.
- Building type, new-build/re-roofing status and approximate roof area.
- Roof photos, sketches or drawings.
- The desired product direction: glass tile appearance, metal sheet coverage, or a comparison of both.
- Known roof conditions such as skylights, valleys, penetrations or complex geometry.
- Buyer role, expected timeline and whether the local roofer/electrical team has already been selected.
