When you have followed the operating instructions closely, found that your solar roof is malfunctioning and found out which solar roof tiles are broken, then the next most important thing is to replace the faulty tiles without delay.

Replacing photovoltaic tiles requires following safety procedures and the correct method to ensure that the new solar roof tiles are securely installed and that the system operates correctly. Here are the steps in detail:

1. Preparation

Ensure safety: Wear insulated gloves and have the required tools ready, including a heat gun, screwdriver, wrench, and electrician's tools.

Disconnect operation: Turn off the main switch of the PV system and disconnect the grid connection to ensure that the whole system is in a no-power state, to ensure the safety of the construction personnel and the electrical system.

2. Check the damaged solar roof tiles

Visual confirmation: reconfirm the solar roof tiles that need to be replaced and make sure that no other normal pv tiles will be operated by mistake.

Record the location: Record the location of the damaged pv tiles to facilitate subsequent installation.

3. Remove damaged solar tiles

Due to the special bottom-to-top tiling technique of the solar roof + screw fixing, it is not possible to remove individual solar roof tiles from the roof.

Removing the fixings: Using a hot air gun, melt the fixing adhesive between the PV module and the bottom support so that the PV module of the solar roof tiles can be removed.

Careful removal: Remove the damaged PV module carefully to avoid damage to the surrounding solar roof tiles.

4. Preparing the new PV module

Inspection of new tiles: Check that the new PV modules are in good condition and ensure that their quality and specifications are consistent with the original solar roof tiles.

Prepare for installation: Prepare the new PV modules according to the installation instructions for the PV modules, paying particular attention to the integrity of the modules by holding them gently.

5. Installation of new solar roof tiles

Installation of solar roof tiles: Apply special fixing adhesive on the bottom support and install the new PV module on the correct position of the bottom support, wait for the adhesive to dry and fix it firmly, the PV tiles will be replaced, make sure that the PV tiles are tightly fitted to the roof.

Check the firmness: Gently shake the solar roof tiles to make sure they are firmly fixed and will not move.

6. System restoration

Grid connection: Reconnect the PV system to the grid and make sure that all electrical connections are correct.

Restore power: Turn on the main switch of the PV system and restore power supply.

7. Inspection and testing

Initial inspection: Visually inspect the new solar roof tiles and their surrounding shingles to ensure that there is no damage or looseness.

System test: Check the power generation performance of the pv tiles and the overall operation of the system through the monitoring system or manual test to make sure there is no failure.

8. Regular Inspection and Maintenance

Regular visual inspection of the roof to confirm whether there is any foreign matter covering, breakage or obvious abnormality.

Regularly monitor the power generation through cell phone or computer PV system app to ensure that solar roof tiles maintain normal operation without obvious abnormalities.

Precautions

SAFETY FIRST: Ensure that safety protocols are followed throughout the operation, especially during electrical operation.

Professional operation: If you do not have professional skills, it is recommended to ask a professional technician to carry out the replacement operation.

Maintenance records: Record the details of the replacement operation, including the time of replacement, the reason and the specifications of the new shingle, to facilitate subsequent maintenance and management.

Prevention is better than cure. Solar roof is an investment with a long-term return rate, and as it is a long-lasting companion of the homeowner, regular monitoring and inspection is especially important.
