What should be agreed before removing and reinstalling solar panels for roof repairs?

What you will see

• Waterproofing work proposed beneath an existing array.
• A roofing contractor asking for cables or supports to be moved.
• Uncertainty about equipment storage and responsibility.
• No allowance for testing after reinstallation.

Why it happens

Commissioning provides evidence that an installed PV system is ready for operation. DOE guidance includes installation verification and commissioning within the system lifecycle; a disturbed installation needs an appropriate review of the work completed before handover.

Agree on the affected area, outage expectations, roof-repair sequence and responsibility for each activity. Record the condition of the equipment before removal and preserve its identification.

The reinstated arrangement should be documented. If the layout, supports, modules or cable routes change, ask which design checks and updated drawings are required. Roof-warranty questions should be resolved with the relevant roofing provider.

What you can check yourself

• Gather the existing layout, serial list and commissioning record.
• Confirm a suitable storage arrangement with the attending team.
• Ask what the removal and reinstatement quotation includes.
• Agree how pre-existing damage will be recorded.
• Plan essential electricity needs for the work period without assuming that backup will remain available throughout.

What not to do

• Do not let unqualified workers disconnect PV wiring or stack panels casually. Do not reconnect equipment just to check whether it still works. Avoid signing completion solely because generation has resumed.

• Contact us before roof work is scheduled so access, electrical work and reinstatement can be coordinated.
