What Should a PV Cable Route Review Cover at Roof Interfaces

Review the route as part of the roof arrangement as well as the electrical design. The team should identify support, protection, movement, drainage and roof-entry interfaces for the selected cables and equipment. A line drawn between module and inverter is not a complete cable-routing proposal.

Practical review checklist

· Map the whole route. Show roof runs, transitions, entries and the inverter location on coordinated drawings.

· Identify support interfaces. Ask the electrical and roof reviewers how the proposed supports interact with the actual substrate.

· Record crossings. Flag drainage, access routes, movement joints and other services that require coordinated details.

· Retain equipment limits. Use the selected manufacturers' current cable and connector instructions in the design review.

When to request clarification

Escalate unsupported route sections or entries without an accepted roof detail. Do not infer connector compatibility from similar appearance or prescribe universal support spacing.

Questions buyers ask

Can a routing sketch replace the electrical design? No. It records interfaces for review, not cable sizing, protection or installation approval.

Who confirms the final project requirements? The appointed project reviewers and relevant manufacturers should confirm requirements for the actual product, roof and location.

Information to send with an enquiry

Send layout and electrical revisions, proposed cable and connector identities, entry details and roof constraints.

This is a project discussion checklist, not an installation instruction or an approval. The selected manufacturers, project engineer and local authority must confirm the applicable requirements.

光伏线缆路径审查需要覆盖哪些屋面接口

线缆路径既属于电气设计，也属于屋面协调。针对拟用线缆与设备识别支承、防护、变形、排水及入口接口；在组件与逆变器之间画一条线并不是完整路径方案。

实用核对清单

· 绘制全路径：协调屋面段、转换、入口及逆变器位置。

· 识别支承接口：由电气和屋面审阅者确认支承与基材关系。

· 记录交叉：标记排水、通行、变形缝及其他服务接口。

· 保留设备边界：设计审查采用所选线缆、连接器的当前说明。

需要澄清的情况

无支承路段或缺少确认屋面入口详图时升级处理，不凭外观认定连接器兼容，不给通用支承间距。
