Power Generation System Restoration
1、Grid connection: Reconnect the PV system to the grid to ensure that all electrical connections are correct.
2、Restore power: Open the main switch of the PV system to restore power.
Inspection And Testing
1、Preliminary inspection: Visually inspect the new solar roof tiles and surrounding tiles to ensure that there is no damage or looseness.
2、System test: Check the power generation performance of the solar roof tiles and the overall operation of the system through the monitoring system or manual test to ensure that there is no failure.
Regular Inspection And Maintenance
1、 Regular inspection of the solar roof tile to ensure that the roof is not covered with any foreign matter, broken, or obvious abnormalities.
2、Regular monitoring of power generation through cell phone or computer PV system application to ensure that the solar roof tile saves normal operation and has no obvious abnormalities.
Preventive Measures
Safety: Ensure that the whole operation process, especially the electrical operation process, complies with the safety norms.
Professional: If you do not have professional installation skills and operating experience, it is recommended to ask a professional technician for a replacement.
Record: Record the details of the replacement operation, including the time of replacement, the reason, and the specifications of the new tile, to facilitate future maintenance and management Prevention is better than maintenance, solar roof tiles have a long-term and high return on investment, as a long-term companion with the owners of the living space, regular testing and inspection is particularly important!
