What Material Compatibility Evidence Should a Rooftop PV Buyer Request

Review the proposed materials as an interface set, not as isolated product names. Roof coatings, metals, adhesives and attachment components can have different compatibility limits. Ask the relevant manufacturers to identify the actual materials and the evidence supporting their proposed combination under the project's exposure conditions.

Practical review checklist

· Identify the substrate. Record the roof material, coating system, condition and any previous repairs or surface treatment.

· List contact pairs. Show which materials touch, where water may be retained and which details are still provisional.

· Request applicable evidence. Ask for written compatibility limits and the installation document revision for the offered combination.

· Assign acceptance. Identify the roof provider, component supplier and project reviewer who must resolve any disagreement.

When to request clarification

Do not treat a generic corrosion-resistance label as approval for every roof coating or attachment pair. Keep unidentified materials and unresolved manufacturer comments as open conditions.

Questions buyers ask

Does a certificate replace a compatibility review? A document supports only its stated scope; check whether the proposed material interface is actually addressed.

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 material identities, exposure information, proposed interface details and the exact question requiring written confirmation.

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.

屋顶光伏采购应索取哪些材料兼容性资料

应按接口组合审查屋面涂层、金属、胶粘材料与固定件，而不是仅核对产品名称。由相关制造商识别真实材料及项目环境，并说明组合适用的证据和限制。

实用核对清单

· 识别基材：记录材质、涂层、状态和既有维修或处理。

· 列出接触组合：标明接触材料、可能滞水位置及暂定详图。

· 索取适用证据：要求对应组合的书面兼容边界和安装文件版本。

· 明确确认责任：列出屋面、部件供应方及项目审阅者。

需要澄清的情况

不能把一般耐腐蚀标签视为所有涂层与材料组合的许可；未知材料和未解决意见应保留条件。
