Does your roof need repairs or does your roof terrace need new waterproofing, while your solar panels are already operating? Before you schedule the roofing crew, plan the solar part of the work too. Temporarily removing the panels requires its own scope, a person responsible, and a plan for putting them back.
The goal is to receive a tested system back, with a clear record of what was kept or changed. The guide below will help you prepare for this process without taking on technical work yourself.
Start with a joint site inspection and a clearly defined scope of work
Ask the person responsible for the roofing work and the qualified solar installer to coordinate before you finalize the quote. They need to know which area will be repaired, how it will be accessed, and whether the roofing material, geometry, or mounting positions will change.
A localized repair and a complete roof reconstruction have different requirements. Ask whether part or all of the installation needs to be removed and who will document that decision. The need to remove panels and mounts during roof replacement is also noted by the U.S. Department of Energy.
For guidance on whether the finished surface is compatible with the mounts, you can consult our guide to roof terrace waterproofing and solar panels. With an existing system, there is one additional critical issue: how the equipment will be removed and put back.
Record what is there before anything is removed
Gather the original design, installation documentation, and maintenance history. Ask the installer to fill in any gaps in the records. An organized file includes:
- The number, models, and available serial numbers of the panels and inverter.
- The equipment layout and photos of its condition before work begins.
- A record of any existing damage and messages in the app.
- Saved production history and access to the monitoring account.
- Details of the mounts and any wiring plans you have.
You do not need to climb onto the roof to take photos or look for labels. Leave documentation that requires working at height to the professionals. Recording the system before it is removed helps clarify later what was handed over, what was reused, and what needed replacing.
Agree separately on removal, storage, and reinstallation
A quote that simply says “solar panel relocation” leaves several questions unanswered. Ask it to describe the safe shutdown by a qualified technician, removal, transportation, storage, reinstallation, and checks before the system is brought back into operation.
Clarify who arranges access and lifting equipment, who takes delivery of the equipment at the storage location, and who is responsible for protecting it at each stage. If any components are found to be damaged, agree that you will be told the reason and any additional cost before you approve a replacement.
Tesla’s documentation on temporary removal and reinstallation distinguishes between the two phases and provides for a secure storage area. It refers to Tesla’s own services and contracts; its procedures and timeframes are not a standard for a project in Greece.
Plan for storage before the crew arrives
Choose a suitable area with the installer, protected from work, impact, and unauthorized access. Ask what packaging and support method are planned for your specific panels, and how their connections will be protected.
Instructions vary by product. For example, the Trinasolar manual for specific module series includes requirements for dry, ventilated temporary storage and careful handling. Ask that the instructions for your equipment be followed rather than simply agreeing that the panels “will be put somewhere.”
Do not disconnect or move the panels yourself. The same manual points out that solar panels generate electrical voltage when exposed to light, even when they are not connected to the rest of the system. This work must be carried out by appropriately qualified professionals.
Plan for the period without production
Ask for a coordinated schedule showing the sequence of work and a point of contact. It should cover removal, the roofing work, confirmation that the roof is ready, and the return of the solar crew. Plan how you will be informed if the weather or hidden damage changes the schedule.
In a hypothetical example, the construction work may be complete, but confirmation that the new surface is ready for the mounts may still be pending. If it has not been agreed who will provide that confirmation, reinstallation may be delayed. There is no single waiting period that applies to all materials and structures.
For the time the system is offline, ask for an estimate of the production that will be unavailable, with the assumptions clearly stated. A system’s production on a previous day does not guarantee what it would have produced on different dates and in different weather conditions.
Do not assume the same final layout
If the roof pitch, covering material, heights, or obstacles on the roof change, request a new assessment of the mounting and layout. If the proposal includes different panels or a change in capacity, distinguish it from simply reinstalling the existing equipment.
Before approving changes, ask the responsible engineer to explain which technical, contractual, and administrative steps are required for your specific installation. Do not assume that every change is routine maintenance.
Have the system handed back to you with documentation
Returning the panels to the roof does not, by itself, complete the process. Ask for a record of the checks carried out by the responsible technician, the components replaced, and the final layout. Use our guide to the solar system handover.
Confirm that you have access to monitoring again and agree on who will review any alerts after the system restarts. Keep photos of the completed roof in your records, taken before critical areas are covered, along with the deliverables from both teams.
At Solar Home, you can discuss your solar system’s needs before scheduling work on your property. Contact us, with your system details and a description of the proposed renovation available, so we can review the photovoltaic aspects of the work.
